+## Requirements
+
+- [Neovim](https://neovim.io/) 0.6 or later
+- Lint task requires [luacheck](https://github.com/luarocks/luacheck#installation) and [stylua](https://github.com/JohnnyMorganz/StyLua). If using nix, you can use `nix develop` to install these to a local nix shell.
+- Documentation is generated by `scripts/docgen.lua`.
+  - Only works on linux and macOS
+
+## Scope of lspconfig
+
+The point of lspconfig is to provide the minimal configuration necessary for a server to act in compliance with the language server protocol. In general, if a server requires custom client-side commands or  off-spec handlers, then the server configuration should be added *without* those in lspconfig and receive a dedicated plugin such as nvim-jdtls, nvim-metals, etc.
+
+## Pull requests (PRs)
+
+- To avoid duplicate work, create a draft pull request.
+- Avoid cosmetic changes to unrelated files in the same commit.
+- Use a [feature branch](https://www.atlassian.com/git/tutorials/comparing-workflows) instead of the master branch.
+- Use a **rebase workflow** for small PRs.
+  - After addressing review comments, it's fine to rebase and force-push.
+
+## Adding a server to lspconfig
+
+The general form of adding a new language server is to start with a minimal skeleton. This includes populated the `config` table with a `default_config` and `docs` table.
+
+When choosing a server name, convert all dashes (`-`) to underscores (`_`) If the name of the server is a unique name (`pyright`, `clangd`) or a commonly used abbreviation (`zls`), prefer this as the server name. If the server instead follows the pattern x-language-server, prefer the convention `x_ls` (`jsonnet_ls`). 
+
+`default_config` should include, at minimum the following:
+* `cmd`: a list which includes the executable name as the first entry, with arguments constituting subsequent list elements (`--stdio` is common).
+Note that Windows has a limitation when it comes to directly invoking a server that's installed by `npm` or `gem`, so it requires additional handling.
+
+```lua
+local bin_name = 'typescript-language-server'
+local cmd = { bin_name, '--stdio' }
+
+if vim.fn.has 'win32' == 1 then
+  cmd = { 'cmd.exe', '/C', bin_name, '--stdio' }
+end
+```
+
+* `filetypes`: a list for filetypes a 
+* `root_dir`: a function (or function handle) which returns the root of the project used to determine if lspconfig should launch a new language server, or attach a previously launched server when you open a new buffer matching the filetype of the server. Note, lspconfig does not offer a dedicated single file mode (this is not codified in the spec). Do not add `vim.fn.cwd` or `util.path.dirname` in `root_dir`. A future version of lspconfig will provide emulation of a single file mode until this is formally codified in the specification. A good fallback is `util.find_git_ancestor`, see other configurations for examples.
+
+Additionally, the following options are often added:
+
+* `init_options`: a table sent during initialization, corresponding to initializationOptions sent in [initializeParams](https://microsoft.github.io/language-server-protocol/specifications/specification-3-17/#initializeParams) as part of the first request sent from client to server during startup.
+* `settings`: a table sent during [`workspace/didChangeConfiguration`](https://microsoft.github.io/language-server-protocol/specifications/specification-3-17/#didChangeConfigurationParams) shortly after server initialization. This is an undocumented convention for most language servers. There is often some duplication with initOptions.
+
+A minimal example for adding a new language server is shown below for `pyright`, a python language server included in lspconfig:
+
+```lua
+-- Only `configs` must be required, util is optional if you are using the root resolver functions, which is usually the case.
+local configs = require 'lspconfig.configs'
+local util = require 'lspconfig.util'
+
+-- Having server name defined here is the convention, this is often times also the first entry in the `cmd` table.
+local server_name = 'pyright'
+
+configs[server_name] = {
+  default_config = {
+    -- This should be executable on the command line, arguments (such as `--stdio`) are additional entries in the list.
+    cmd = { 'pyright-langserver' },

+
+## Commit style
+
+lspconfig, like neovim core, follows the [conventional commit style](https://www.conventionalcommits.org/en/v1.0.0-beta.2/) please submit your commits accordingly. Generally commits will be of the form:
+
+```
+feat: add lua-language-server support
+fix(lua-language-server): update root directory pattern
+docs: update README.md
+```
+
+with the commit body containing additional details.
+
+## Lint
+
+PRs are checked with [luacheck](https://github.com/mpeterv/luacheck), [StyLua](https://github.com/JohnnyMorganz/StyLua) and [selene](https://github.com/Kampfkarren/selene). Please run the linter locally before submitting a PR:
+
+    make lint
+
+## Generating docs
+
+Github Actions automatically generates `server_configurations.md`. Only modify `scripts/README_template.md` or the `docs` table in the server config (the lua file). Do not modify `server_configurations.md` directly.
+
+To preview the generated `server_configurations.md` locally, run `scripts/docgen.lua` from
+`nvim` (from the project root):
+
+    nvim -R -Es +'set rtp+=$PWD' +'luafile scripts/docgen.lua'

+# lspconfig
+
+A [collection of common configurations](doc/server_configurations.md) for Neovim's built-in [language server client](https://neovim.io/doc/user/lsp.html).
+
+This plugin allows for declaratively configuring, launching, and initializing language servers you have installed on your system. 
+**Disclaimer: Language server configurations are provided on a best-effort basis and are community-maintained. See [contributions](#contributions).**
+
+`lspconfig` has extensive help documentation, see `:help lspconfig`.
+
+# LSP overview
+
+Neovim supports the Language Server Protocol (LSP), which means it acts as a client to language servers and includes a Lua framework `vim.lsp` for building enhanced LSP tools. LSP facilitates features like:
+
+- go-to-definition
+- find-references
+- hover
+- completion
+- rename
+- format
+- refactor
+
+Neovim provides an interface for all of these features, and the language server client is designed to be highly extensible to allow plugins to integrate language server features which are not yet present in Neovim core such as [**auto**-completion](https://github.com/neovim/nvim-lspconfig/wiki/Autocompletion) (as opposed to manual completion with omnifunc) and [snippet integration](https://github.com/neovim/nvim-lspconfig/wiki/Snippets).
+
+These features are not implemented in this repo, but in Neovim core. See `:help lsp` for more details.
+
+## Install
+
+* Requires [Neovim v0.6.0](https://github.com/neovim/neovim/releases/tag/v0.6.0) or [Nightly](https://github.com/neovim/neovim/releases/tag/nightly). Update Neovim and 'lspconfig' before reporting an issue.
+
+* Install 'lspconfig' like any other Vim plugin, e.g. with [vim-plug](https://github.com/junegunn/vim-plug):
+
+    ```vim
+    Plug 'neovim/nvim-lspconfig'
+    ```
+
+## Quickstart
+
+1. Install a language server, e.g. [pyright](doc/server_configurations.md#pyright)
+
+    ```bash
+    npm i -g pyright
+    ```
+
+2. Add the language server setup to your init.vim. The server name must match those found in the table of contents in [server_configurations.md](doc/server_configurations.md). This list is also accessible via `:help lspconfig-server-configurations`.
+
+    ```lua
+    lua << EOF
+    require'lspconfig'.pyright.setup{}
+    EOF
+    ```
+
+3. Create a project, this project must contain a file matching the root directory trigger. See [Automatically launching language servers](#Automatically-launching-language-servers) for additional info.
+
+    ```bash
+    mkdir test_python_project
+    cd test_python_project
+    git init
+    touch main.py
+    ```
+
+4. Launch neovim, the language server will now be attached and providing diagnostics (see `:LspInfo`)
+
+    ```
+    nvim main.py
+    ```
+
+5. See [Keybindings and completion](#Keybindings-and-completion) for mapping useful functions and enabling omnifunc completion
+
+## Automatically launching language servers
+
+In order to automatically launch a language server, 'lspconfig' searches up the directory tree from your current buffer to find a file matching the `root_dir` pattern defined in each server's configuration.  For [pyright](doc/server_configurations.md#pyright), this is any directory containing ".git", "setup.py",  "setup.cfg", "pyproject.toml", or "requirements.txt").
+
+Language servers require each project to have a `root` in order to provide completion and search across symbols that may not be defined in your current file, and to avoid having to index your entire filesystem on each startup.
+
+## Enabling additional language servers
+
+Enabling most language servers is as easy as installing the language server, ensuring it is on your PATH, and adding the following to your config:
+
+```vim
+lua << EOF
+require'lspconfig'.rust_analyzer.setup{}
+EOF
+```
+
+For a full list of servers, see [server_configurations.md](doc/server_configurations.md) or `:help lspconfig-server-configurations`. This document contains installation instructions and additional, optional, customization suggestions for each language server. For some servers that are not on your system path (e.g., `jdtls`, `elixirls`), you will be required to manually add `cmd` as an entry in the table passed to `setup`. Most language servers can be installed in less than a minute.
+
+## Keybindings and completion
+
+'lspconfig' does not map keybindings or enable completion by default. Manual, triggered completion can be provided by neovim's built-in omnifunc. For autocompletion, a general purpose [autocompletion plugin](https://github.com/neovim/nvim-lspconfig/wiki/Autocompletion) is required. The following example configuration provides suggested keymaps for the most commonly used language server functions, and manually triggered completion with omnifunc (\<c-x\>\<c-o\>).
+Note: **you must pass the defined `on_attach` as an argument to every `setup {}` call** and **the keybindings in `on_attach` only take effect after the language server has started (attached to the current buffer)**. 
+
+```lua
+lua << EOF
+local nvim_lsp = require('lspconfig')
+
+-- Use an on_attach function to only map the following keys
+-- after the language server attaches to the current buffer
+local on_attach = function(client, bufnr)
+  local function buf_set_keymap(...) vim.api.nvim_buf_set_keymap(bufnr, ...) end
+  local function buf_set_option(...) vim.api.nvim_buf_set_option(bufnr, ...) end
+
+  -- Enable completion triggered by <c-x><c-o>
+  buf_set_option('omnifunc', 'v:lua.vim.lsp.omnifunc')
+
+  -- Mappings.
+  local opts = { noremap=true, silent=true }
+
+  -- See `:help vim.lsp.*` for documentation on any of the below functions
+  buf_set_keymap('n', 'gD', '<cmd>lua vim.lsp.buf.declaration()<CR>', opts)
+  buf_set_keymap('n', 'gd', '<cmd>lua vim.lsp.buf.definition()<CR>', opts)
+  buf_set_keymap('n', 'K', '<cmd>lua vim.lsp.buf.hover()<CR>', opts)

+  buf_set_keymap('n', '<space>wl', '<cmd>lua print(vim.inspect(vim.lsp.buf.list_workspace_folders()))<CR>', opts)
+  buf_set_keymap('n', '<space>D', '<cmd>lua vim.lsp.buf.type_definition()<CR>', opts)
+  buf_set_keymap('n', '<space>rn', '<cmd>lua vim.lsp.buf.rename()<CR>', opts)
+  buf_set_keymap('n', '<space>ca', '<cmd>lua vim.lsp.buf.code_action()<CR>', opts)
+  buf_set_keymap('n', 'gr', '<cmd>lua vim.lsp.buf.references()<CR>', opts)
+  buf_set_keymap('n', '<space>e', '<cmd>lua vim.diagnostic.open_float()<CR>', opts)
+  buf_set_keymap('n', '[d', '<cmd>lua vim.diagnostic.goto_prev()<CR>', opts)
+  buf_set_keymap('n', ']d', '<cmd>lua vim.diagnostic.goto_next()<CR>', opts)
+  buf_set_keymap('n', '<space>q', '<cmd>lua vim.diagnostic.setloclist()<CR>', opts)
+  buf_set_keymap('n', '<space>f', '<cmd>lua vim.lsp.buf.formatting()<CR>', opts)
+
+end
+
+-- Use a loop to conveniently call 'setup' on multiple servers and
+-- map buffer local keybindings when the language server attaches
+local servers = { 'pyright', 'rust_analyzer', 'tsserver' }
+for _, lsp in ipairs(servers) do
+  nvim_lsp[lsp].setup {
+    on_attach = on_attach,
+    flags = {
+      debounce_text_changes = 150,
+    }
+  }
+end
+EOF
+```
+
+The `on_attach` hook is used to only activate the bindings after the language server attaches to the current buffer.
+
+## Debugging
+
+If you have an issue with 'lspconfig', the first step is to reproduce with a [minimal configuration](https://github.com/neovim/nvim-lspconfig/blob/master/test/minimal_init.lua).
+
+The most common reasons a language server does not start or attach are:
+
+1. The language server is not installed. 'lspconfig' does not install language servers for you. You should be able to run the `cmd` defined in each server's lua module from the command line and see that the language server starts. If the `cmd` is an executable name, ensure it is on your path.
+
+2. Not triggering root detection. The language server will only start if it is opened in a directory, or child directory, containing a file which signals the *root* of the project. Most of the time, this is a `.git` folder, but each server defines the root config in the lua file. See [server_configurations.md](doc/server_configurations.md) or the source for the list of root directories.
+
+3. Misconfiguration. You must pass `on_attach` and `capabilities` for **each** `setup {}` if you want these to take effect. You must also **not call `setup {}` twice for the same server**. The second call to `setup {}` will overwrite the first.
+
+:LspInfo provides a handy overview of your active and configured language servers.  Note, that it will not report any configuration changes applied in `on_new_config`.
+
+Before reporting a bug, check your logs and the output of `:LspInfo`. Add the following to your init.vim to enable logging:
+
+```lua
+lua << EOF
+vim.lsp.set_log_level("debug")
+EOF
+```
+Attempt to run the language server, and open the log with:
+```
+:lua vim.cmd('e'..vim.lsp.get_log_path())
+```
+Most of the time, the reason for failure is present in the logs.
+
+## Built-in commands
+
+* `:LspInfo` shows the status of active and configured language servers.
+
+The following support tab-completion for all arguments:
+
+* `:LspStart <config_name>` Start the requested server name. Will only successfully start if the command detects a root directory matching the current config. Pass `autostart = false` to your `.setup{}` call for a language server if you would like to launch clients solely with this command. Defaults to all servers matching current buffer filetype.
+* `:LspStop <client_id>` Defaults to stopping all buffer clients.
+* `:LspRestart <client_id>` Defaults to restarting all buffer clients.
+

+## Contributions
+
+If you are missing a language server on the list in [server_configurations.md](doc/server_configurations.md), contributing
+a new configuration for it would be appreciated. You can follow these steps:
+
+1. Read [CONTRIBUTING.md](CONTRIBUTING.md).
+
+2. Choose a language from [the coc.nvim wiki](https://github.com/neoclide/coc.nvim/wiki/Language-servers) or
+[emacs-lsp](https://github.com/emacs-lsp/lsp-mode#supported-languages).
+
+3. Create a new file at `lua/lspconfig/SERVER_NAME.lua`.
+
+    - Copy an [existing config](https://github.com/neovim/nvim-lspconfig/blob/master/lua/lspconfig/server_configurations/)
+      to get started. Most configs are simple. For an extensive example see
+      [texlab.lua](https://github.com/neovim/nvim-lspconfig/blob/master/lua/lspconfig/server_configurations/texlab.lua).
+
+4. Ask questions on our [Discourse](https://neovim.discourse.group/c/7-category/7) or in the [Neovim Gitter](https://gitter.im/neovim/neovim).
+
+You can also help out by testing [PRs with the `needs-testing`](https://github.com/neovim/nvim-lspconfig/issues?q=is%3Apr+is%3Aopen+label%3Aneeds-testing) label) that affect language servers you use regularly.

+INTRODUCTION                                                         *lspconfig*
+
+`lspconfig` is a collection of community contributed configurations for the
+built-in language server client in Neovim core. This plugin provides four
+primary functionalities:
+
+ - default launch commands, initialization options, and settings for each
+   server
+ - a root directory resolver which attempts to detect the root of your project
+ - an autocommand mapping that either launches a new language server or
+   attempts to attach a language server to each opened buffer if it falls
+   under a tracked project
+ - utility commands such as LspInfo, LspStart, LspStop, and LspRestart for
+   managing language server instances
+
+`lspconfig` is not required to use the built-in client, it is only one front-end
+interface for when a language server specific plugin is not available.
+
+See |lspconfig-server-configurations| by typing `K` over it for the complete
+list of language servers configurations.
+
+==============================================================================
+LSP OVERVIEW                                                     *lspconfig-lsp*
+
+Nvim supports the Language Server Protocol (LSP) via the built-in language
+server client. LSP facilitates many features, some of which include:
+
+- go-to-definition
+- find-references
+- hover
+- completion
+- rename
+- format
+- refactor
+
+These features are implemented in Neovim core, not `lspconfig`. See `:help lsp`
+for more details.
+
+NOTE: Feature availability depends on the implementation details of the
+server. A server may implement only a subset of these features. Always
+consult the server documentation before filing a bug report on a missing
+feature.
+
+==============================================================================
+QUICKSTART                                                *lspconfig-quickstart*
+
+- ensure the server is installed and executable from the command line
+
+- enable the server in your Neovim configuration (Lua example):
+>
+    require'lspconfig'.clangd.setup{}
+<
+- create a new project, ensure that it contains a root marker which matches the
+  server requirements specified in |lspconfig-server-configurations|.
+
+- open a file within that project, such as `main.c`.
+
+- If you need more information about a server configuration, read the corresponding
+  entry in |lspconfig-server-configurations|.
+
+==============================================================================
+THE SETUP METAMETHOD                                           *lspconfig-setup*
+
+`lspconfig` consists of a collection of language server configurations. Each
+configuration exposes a `setup {}` metamethod which makes it easy to directly
+use the default configuration or selectively override the defaults. 
+`setup {}` is the primary interface by which users interact with `lspconfig`.
+
+Using the default configuration for a server is simple:
+>
+    require'lspconfig'.clangd.setup{}
+<
+The available server names are listed in |lspconfig-server-configurations| and
+match the server name in `config.SERVER_NAME` defined in each configuration's
+source file.
+
+The purpose of `setup{}` is to wrap the call to Nvim's built-in 
+`vim.lsp.start_client()` with an autocommand that automatically launch a 
+language server.
+
+This autocommand calls `start_client()` or `vim.lsp.buf_attach_client()` 
+depending on whether the current file belongs to a project with a currently
+running client. See |lspconfig-root-detection| for more details.
+
+The `setup{}` function takes a table which contains a superset of the keys
+listed in `:help vim.lsp.start_client()` with the following unique entries:
+
+- {root_dir}
+
+    `function(filename, bufnr)`
+
+    Returns either a filepath (string) or nil. The language server will only
+    start if the function returns a filepath.
+
+    If a root directory (string) is returned which is unique from any
+    previously returned root_dir, a new server will be spawned with that
+    root directory. See |lspconfig-root-detection| for more details
+
+- {name}
+
+    `string`
+
+    Defaults to the server's name (`clangd`, `pyright`, etc.).
+
+- {filetypes}
+
+    `list[string] | nil`
+
+    Set of filetypes for which to attempt to resolve {root_dir}.
+
+    May be empty, or server may specify a default value.
+
+- {autostart}
+
+    `bool` (default: true)
+
+    Controls if the `FileType` autocommand that launches a language server is
+    created. If `false`, allows for deferring language servers until manually
+    launched with `:LspStart` (|lspconfig-commands|).
+
+- {single_file_support}
+
+    `bool` (default: nil)
+
+    Determines if a server is started without a matching root directory.
+    See |lspconfig-single-file-support|.
+
+- {on_new_config}
+
+    `function(new_config, new_root_dir)`
+
+    Function executed after a root directory is detected. This is used to
+    modify the server configuration (including `cmd` itself). Most commonly,
+    this is used to inject additional arguments into `cmd`.
+
+    If overriding `on_new_config`, ensure that you read the
+    `on_new_config` defined in the source file of the default configuration
+    in `lspconfig`. The original `on_new_config` snippet for a given server
+    should likely be included in your new override. Some configurations
+    use `on_new_config` to dynamically set or modify `cmd`.
+
+Note: all entries passed to `setup {}` override the entry in the default
+configuration. There is no composition.
+
+All `config` elements described in `:help vim.lsp.start_client()` can
+additionally be overridden via the `setup {}` call. The most commonly
+passed overrides to `setup {}` are:
+
+- {capabilities} `table <string, string|table|bool|function>`
+
+  a table which represents the neovim client capabilities. Useful for
+  broadcasting to the server additional functionality (snippets, off-protocol
+  features) provided by plugins.
+
+- {cmd} `list[string]`
+
+  a list where each entry corresponds to the blankspace delimited part of
+  the command that launches the server. The first entry is the binary used
+  to run the language server. Additional entries are passed as arguments.
+
+  The equivalent `cmd` for: 
+>
+  foo --bar baz
+<
+  is:
+>
+  {'foo', '--bar', 'baz}
+<
+- {handlers} `list[functions]`
+
+  a list of handlers which override the function used to process a response
+  from a given language server. Applied only to the server referenced by
+  setup. See |lsp-handler|.
+
+- {init_options} `table <string, string|table|bool>`
+
+  a table passed during the initialization notification after launching
+  a language server. Equivalent to the `initializationOptions` field found
+  in `InitializeParams` in the LSP specification.
+
+  See upstream server documentation for available initialization
+  options.
+
+- {on_attach} `function(client, bufnr)`
+
+  Callback invoked by Nvim's built-in client when attaching a buffer to a
+  language server. Often used to set Nvim (buffer or global) options or to
+  override the Nvim client properties (`resolved_capabilities`) after a
+  language server attaches. Most commonly used for settings buffer
+  local keybindings. See |lspconfig-keybindings| for a usage example.
+
+- {settings} `table <string, string|table|bool>`  
+
+  The `settings` table is sent in `on_init` via a
+  `workspace/didChangeConfiguration` notification from the Nvim client to
+  the language server. These settings allow a user to change optional runtime
+  settings of the language server. 
+
+  The script that automatically generates `server_configurations.md` converts
+  the `package.json` referenced in a server configuration source file
+  into a list of optional settings listed in |lspconfig-server-configurations|.
+
+  As an example, to set the following settings found in the pyright
+  documentation:
+
+  `pyright.disableLanguageServices`: `boolean`
+  `pyright.disableOrganizeImports`: `boolean`
+
+  Nested keys need to be translated into a nested table and passed to
+  the settings field in `setup {}` as follows:
+>
+  require('lspconfig').pyright.setup{
+    settings = {
+      pyright = {
+          disableLanguageServices = true,
+          disableOrganizeImports  = true,
+        }
+    }
+  }
+<
+  
+  Note that the autogenerated settings occasionally include VS code specific
+  settings. If a setting is not respected by a language server, consult
+  upstream documentation.
+
+
+==============================================================================
+OVERRIDING GLOBAL DEFAULTS                           *lspconfig-global-defaults*
+
+The global defaults for all servers can be overridden by extending the
+`default_config` table.
+
+>
+  local lspconfig = require'lspconfig'
+  lspconfig.util.default_config = vim.tbl_extend(
+    "force",
+    lspconfig.util.default_config,
+    {
+      autostart = false,
+      handlers = {
+        ["window/logMessage"] = function(err, method, params, client_id)
+            if params and params.type <= vim.lsp.protocol.MessageType.Log then
+              vim.lsp.handlers["window/logMessage"](err, method, params, client_id)
+            end
+          end;
+        ["window/showMessage"] = function(err, method, params, client_id)
+            if params and params.type <= vim.lsp.protocol.MessageType.Warning.Error then
+              vim.lsp.handlers["window/showMessage"](err, method, params, client_id)
+            end
+          end;
+      }
+    }
+  )
+<
+`setup {}` can additionally override these defaults in subsequent calls.
+
+==============================================================================
+SERVER CONFIGURATIONS                                 *lspconfig-configurations*
+
+See |lspconfig-server-configurations| by typing `K` over it for the complete
+list of language servers configurations.
+
+While the `setup {}` function is the primary interface to `lspconfig`, for
+servers for which there is not a configuration, it is necessary to define a
+configuration directly. This can be useful if there is an outstanding PR that
+is in review, or when developing a language server that is unavailable
+publicly. This can be done through the `configs` module.
+
+The `configs` module is a singleton where configs are defined. The schema for
+validating using `vim.validate` is:
+>
+    configs.SERVER_NAME = {
+      default_config = {'t'};
+      on_new_config = {'f', true};
+      on_attach = {'f', true};
+      commands = {'t', true};
+      docs = {'t', true};
+    }
+<
+where the structure of the docs table is as follows:
+>
+    docs = {
+      description = {'s', true};
+      default_config = {'t', true};
+    }
+<
+`commands` is a map of `name:definition` key:value pairs, where `definition`
+is a list whose first value is a function implementing the command, and the
+rest are either array values which will be formed into flags for the command,
+or special keys like `description`. Example:
+>
+  commands = {
+    TexlabBuild = {
+      function()
+        buf_build(0)
+      end;
+      "-range";
+      description = "Build the current buffer";
+    };
+  };
+<
+The `configs.__newindex` metamethod consumes the config definition and returns
+an object with a `setup()` method, to be invoked by users:
+>
+    require'lspconfig'.SERVER_NAME.setup{}
+
+After you set `configs.SERVER_NAME` you can add arbitrary language-specific
+functions to it if necessary.
+
+Example:
+
+>
+    configs.texlab.buf_build = buf_build
+<
+==============================================================================
+ADDING NEW SERVERS                                    *lspconfig-adding-servers*
+
+The three steps for adding and enabling a new server configuration are:
+
+- load the `lspconfig` module (note that this is a stylistic choice)
+>
+   local lspconfig = require 'lspconfig'
+<
+- define the configuration
+
+>
+   local configs = require 'lspconfig.configs'
+
+   -- Check if the config is already defined (useful when reloading this file)
+   if not configs.foo_lsp then
+     configs.foo_lsp = {
+       default_config = {
+         cmd = {'/home/neovim/lua-language-server/run.sh'};
+         filetypes = {'lua'};
+         root_dir = function(fname)
+           return lspconfig.util.find_git_ancestor(fname)
+         end;
+         settings = {};
+       };
+     }
+   end
+
+- call `setup()` to enable the FileType autocmd
+>
+   lspconfig.foo_lsp.setup{}
+<
+==============================================================================
+ROOT DETECTION                                        *lspconfig-root-detection*
+                                                            *lspconfig-root-dir*
+
+A project's `root_dir` is used by `lspconfig` to determine whether `lspconfig`
+should start a new server, or attach a previous one, to the current file.
+
+`lspconfig` automatically launches language servers by defining a filetype
+autocommand based on the `filetypes` specified in the default configuration of
+each server, optionally overridable by the `filetypes` table passed to
+`setup`.
+
+This autocommand triggers a search from the current file position in the
+filesystem hierarchy up to the top level directory of your filesystem. The
+`root_dir` entry of each configuration is a function that returns true if the
+current directory in this traversal matches a given root pattern.
+
+The following utility functions are provided by `lspconfig`. Each function call
+below returns a function that takes as its argument the current buffer path.
+
+- `util.root_pattern`: function which takes multiple arguments, each 
+  corresponding to a different root pattern against which the contents of the
+  current directory are matched using |vim.fin.glob()| while traversing up the
+  filesystem.
+>
+   root_dir = util.root_pattern('pyproject.toml', 'requirements.txt')
+<
+- `util.find_git_ancestor`: a function that locates the first parent directory
+  containing a `.git` directory.
+>
+   root_dir = util.find_git_ancestor
+
+- `util.find_node_modules_ancestor`: a function that locates the first parent
+  directory containing a `node_modules` directory.
+>
+   root_dir = util.find_node_modules_ancestor
+<
+
+- `util.find_package_json_ancestor`: a function that locates the first parent
+  directory containing a `package.json`.
+>
+   root_dir = util.find_json_ancestor
+<
+Note: On Windows, `lspconfig` always assumes forward slash normalized paths with
+capitalized drive letters.
+
+==============================================================================
+ADVANCED ROOT DIRECTORY DETECTION                      *lspconfig-root-advanced* 
+                                                    *lspconfig-root-composition*
+
+The `root_dir` key in `config` and `setup` can hold any function of the form
+>
+  function custom_root_dir(filename, bufnr)
+  returns nil | string
+>
+This allows for rich composition of root directory patterns which is necessary
+for some project structures. Example (for Kotlin):
+>
+  local root_files = {
+    'settings.gradle', -- Gradle (multi-project)
+    'settings.gradle.kts', -- Gradle (multi-project)
+    'build.xml', -- Ant
+    'pom.xml', -- Maven
+  }
+
+  local fallback_root_files = {
+    'build.gradle', -- Gradle
+    'build.gradle.kts', -- Gradle
+  }
+  root_dir = function(fname)
+    local primary = util.root_pattern(unpack(root_files))(fname)
+    local fallback = util.root_pattern(unpack(fallback_root_files))(fname)
+    return primary or fallback
+  end
+<
+Browsing the source of the default configurations is recommended.
+
+==============================================================================
+SINGLE FILE SUPPORT                              *lspconfig-single-file-support*
+
+Language servers require each project to have a `root` in order to provide
+features that require cross-file indexing. 
+
+Some servers support not passing a root directory as a proxy for single file
+mode under which cross-file features may be degraded.
+
+`lspconfig` offers limited support for an implicit single-file mode by:
+
+- first trying to resolve the root directory pattern
+- then, if `single_file_support` is enabled for a given language server
+  configuration, starting the server without sending `rootDirectory` or
+  `workspaceFolders` during initialization.
+- attaching subsequent files in the parent directory to the same server
+  instance, depending on filetype.
+
+Cross-file features (navigation, hover) may or may not work depending on the
+language server. For a full feature-set, consider moving your files to a
+directory with a project structure `lspconfig` can infer.
+
+Note that in the event that the LSP specification is extended to support a
+standard for single-file mode, lspconfig will adopt that standard.
+
+==============================================================================
+COMMANDS                                                    *lspconfig-commands*
+
+- `:LspInfo` shows the status of active and configured language servers. Note
+  that client id refers to the Nvim RPC instance connected to a given
+  language server.
+
+The following commands support tab-completion for all arguments. All commands
+that require a client id can either leverage tab-completion or the info
+contained in `:LspInfo`:
+
+- `:LspStart <config_name>` launches the requested (configured) client, but only
+  if it successfully resolves a root directory. Note: Defaults to all
+  configured servers matching the current buffer filetype.
+- `:LspStop <client_id>` stops the server with the given client id. Defaults to
+  stopping all servers active on the current buffer.
+- `:LspRestart <client_id>` restarts the client with the given client id, and
+  will attempt to reattach to all previously attached buffers.
+
+==============================================================================
+EXAMPLE KEYBINDINGS                                      *lspconfig-keybindings*
+
+`lspconfig`, and the core client, do not map any keybindings by default. The
+following is an example Lua block which demonstrates how to leverage
+`on-attach` to selectively apply keybindings after a language servers has
+attached to a given buffer.
+>
+    local nvim_lsp = require('lspconfig')
+
+    -- Use an on_attach function to only map the following keys
+    -- after the language server attaches to the current buffer
+    local on_attach = function(client, bufnr)
+      local function buf_set_keymap(...) vim.api.nvim_buf_set_keymap(bufnr, ...) end

+      -- Mappings.
+      local opts = { noremap=true, silent=true }
+
+      -- See `:help vim.lsp.*` for documentation on any of the below functions

+COMPLETION SUPPORT                                        *lspconfig-completion*
+
+Manually triggered completion can be provided by Nvim's built-in omnifunc.
+See `:help omnifunc` for more details.

+For autocompletion, Nvim does not offer built-in functionality at this time.

+DEBUGGING                                                  *lspconfig-debugging*
+
+While using language servers should be easy, debugging issues can be
+challenging. First, it is important to identify the source of the issue, which
+is typically (in rough order):
+
+- the language server itself
+- a plugin
+- overrides in a user configuration
+- the built-in client in Nvim core
+- `lspconfig`
+
+The first step in debugging is to test with a minimal configuration (such as
+`../test/minimal_init.lua`). Historically, many users problems are due to
+plugins or misconfiguration.
+
+Should that fail, identifying which component is the culprit is challenging.
+The following are the only categories of bugs that pertain to `lspconfig`.
+
+- The root directory inferred for your project is wrong, or it should be
+  detected but is not due to a bug in the `lspconfig` path utilities.
+- The server is launching, but you believe that the default settings,
+  initialization options, or command arguments are suboptimal and should be
+  replaced based on your understanding of the server documentation.
+
+All bugs Nvim's built-in client should be reported to the Nvim core issue
+tracker. All bugs pertaining to plugins should be reported to the respective
+plugin. All missing features in a language server should be reported to the
+upstream language server issue tracker.
+
+For debugging `lspconfig` issues, the most common hurdles users face are:
+
+  - The language server is not installed or is otherwise not executable.
+    `lspconfig` does not install language servers for you. Ensure the `cmd`
+    defined in `server_configurations.md` is executable from the command
+    line. If the absolute path to the binary is not supplied in `cmd`, ensure
+    it is on your PATH.
+  - No root detected. `lspconfig` is built around the concept of projects. See
+    |lspconfig-root-detection| for more details. Most of the time,
+    initializing a git repo will suffice.
+  - Misconfiguration. Often users will override `cmd`, `on_init`, or
+    `handlers`. Ensure that you debug by using a stock configuration to ensure
+    your customizations are not introducing issues.
+
+|LspInfo| provides an overview of your active and configured language servers
+which can be useful for debugging.
+
+Note that it will not report any configuration changes applied in
+`on_new_config`.

+LOGGING                                                      *lspconfig-logging*
+
+When debugging language servers, it is helpful to enable additional logging in
+the built-in client, specifically considering the RPC logs. Example:
+>
+  vim.lsp.set_log_level 'trace'
+  if vim.fn.has 'nvim-0.5.1' == 1 then
+    require('vim.lsp.log').set_format_func(vim.inspect)
+  end
+<
+Attempt to run the language server, and open the log with:
+
+>
+    :lua vim.cmd('e'..vim.lsp.get_log_path())
+<
+Note that `ERROR` messages containing `stderr` only indicate that the log was
+sent to `stderr`. Many servers counter-intuitively send harmless messages
+via stderr.
+
+==============================================================================
+SCOPE                                                         *lspconfig-scope*
+
+`lspconfig` is a community effort to create default configurations that fit
+within the scope of an official plugin for Nvim. All features that are not
+strictly providing default configurations for language servers will be removed
+from `lspconfig` in time. The power of the Neovim LSP ecosystem is in the
+composability and flexibility of integrating multiple plugins which maximizes
+user choice and freedom.
+
+`lspconfig` also opts to adhere strictly to the LSP specification, with some
+small allowances when small modifications to a server configuration are
+necessary to enable features critical to its usability. For more featureful
+options, the `lspconfig` wiki lists community created plugins that build upon
+the built-in client to provide functionality tailored to specific language
+servers.

+
+Since Sphinx is highly extensible you will get best results if you install the language server in the same

+```lua
+require'lspconfig'.esbonio.setup {
+  cmd = { '/path/to/virtualenv/bin/python', '-m', 'esbonio' }
+}

+```lua

+The Idris 2 language server.
+
+Plugins for the Idris 2 filetype include
+[Idris2-Vim](https://github.com/edwinb/idris2-vim) (fewer features, stable) and
+[Nvim-Idris2](https://github.com/ShinKage/nvim-idris2) (cutting-edge,
+experimental).
+
+Idris2-Lsp requires a build of Idris 2 that includes the "Idris 2 API" package.
+Package managers with known support for this build include the
+[AUR](https://aur.archlinux.org/packages/idris2-api-git/) and
+[Homebrew](https://formulae.brew.sh/formula/idris2#default).
+
+If your package manager does not support the Idris 2 API, you will need to build
+Idris 2 from source. Refer to the
+[the Idris 2 installation instructions](https://github.com/idris-lang/Idris2/blob/main/INSTALL.md)
+for details.  Steps 5 and 8 are listed as "optional" in that guide, but they are
+necessary in order to make the Idris 2 API available.
+
+You need to install a version of Idris2-Lsp that is compatible with your
+version of Idris 2. There should be a branch corresponding to every released
+Idris 2 version after v0.4.0. Use the latest commit on that branch. For example,
+if you have Idris v0.5.1, you should use the v0.5.1 branch of Idris2-Lsp.
+
+If your Idris 2 version is newer than the newest Idris2-Lsp branch, use the
+latest commit on the `master` branch, and set a reminder to check the Idris2-Lsp
+repo for the release of a compatible versioned branch.
