+Language Server for F# provded by FsAutoComplete (FSAC).
+
+Download a release of FsAutoComplete from [here](https://github.com/fsharp/FsAutoComplete/releases).
+Instructions to compile from source are found on the main repository.
+
+FsAutoComplete requires the [dotnet-sdk](https://dotnet.microsoft.com/download) to be installed.
+
+You may also need to configure the filetype as Vim defaults to Forth for `*.fs` files:
+
+`autocmd BufNewFile,BufRead *.fs,*.fsx,*.fsi set filetype=fsharp`
+
+This is automatically done by plugins such as [vim-polyglot](https://github.com/sheerun/vim-polyglot), [PhilT/vim-fsharp](https://github.com/PhilT/vim-fsharp) or [fsharp/vim-fsharp](https://github.com/fsharp/vim-fsharp).
+
+**By default, this config doesn't have a `cmd` set.** This is because nvim-lspconfig does not make assumptions about your path. You must add the following to your init.vim or init.lua to set `cmd` to the absolute path ($HOME and ~ are not expanded) of your unzipped and compiled fsautocomplete.dll.
+
+```lua
+require'lspconfig'.fsautocomplete.setup{
+  cmd = {'dotnet', 'path/to/fsautocomplete.dll', '--background-service-enabled'}
+}
+```
+    ]];
+  };
+}
