-One of the strengths of **nvf** is convenient aliases to quickly configure LSP
-servers through the Nix module system. By default the LSP packages for relevant
-language modules will be pulled into the closure. If this is not desirable, you
-may provide **a custom LSP package** (e.g., a Bash script that calls a command)
-or **a list of strings** to be interpreted as the command to launch the language
-server. By using a list of strings, you can use this to skip automatic
-installation of a language server, and instead use the one found in your `$PATH`
-during runtime, for example:
-
-```nix
-vim.languages.java = {
-  lsp = {
-    enable = true;
-
-    # This expects 'jdt-language-server' to be in your PATH or in

-    # if the command provided is valid.
-    package = ["jdt-language-server" "-data" "~/.cache/jdtls/workspace"];

+LSP presets provided by NVF via `vim.languages.*.lsp` can be further customized

+discover LSP servers from {env}`PATH`.

   vim.lsp.servers = {
