Lean installation instructions can be found

[here](https://leanprover-community.github.io/get_started.html#regular-install).

The Lean 4 language server is built-in with a Lean 4 install
|
||
|
|
(and can be manually run with, e.g., `lean --server`).
|
||
|
|
|
||
|
|
Note: that if you're using [lean.nvim](https://github.com/Julian/lean.nvim),
|
||
|
|
that plugin fully handles the setup of the Lean language server,
|
||
|
|
and you shouldn't set up `leanls` both with it and `lspconfig`.
