+--- The recommended way is to install guile-lsp-server is using Guix. Unfortunately it is still not available at the official Guix channels, but you can use the provided channel guix.scm in the repo:
+--- ```sh
+--- guix package -f guix.scm
+--- ```
+---
+--- Checkout the repo for more info.
+---
+--- Note: This LSP will start on `scheme.guile` filetype. You can set this file type using `:help modeline` or adding https://gitlab.com/HiPhish/guile.vim to your plugins to automatically set it.
