+---
+--- Written in Go, compilation is needed for `nomad_lsp` to be used. Please see the [original repository](https://github.com/juliosuieras/nomad-lsp).
+---
+--- Add the executable to your system or vim PATH and it will be set to go.
+---
+--- No configuration option is needed unless you choose not to add `nomad-lsp` executable to the PATH. You should know what you are doing if you choose so.
+---
+--- ```lua
+--- vim.lsp.enable('nomad_lsp')
+--- ```
+---
+--- However, a `hcl.nomad` or `nomad` filetype should be defined.
+---
+--- Description of your jobs should be written in `.nomad` files for the LSP client to configure the server's `root_dir` configuration option.
