This guide assumes that you've completed the steps described in Prerequisites.

1. If you're using nix-shell, make sure you can launch the editor from the command line so it inherits your $PATH. Follow the instructions here.
2. Install LSP: Open the command palette and run Package Control: Install Package, then select LSP.
3. Open LSP settings: Preferences -> Package Settings -> LSP -> Settings and add this

   {
    "clients": {
        "haskell-language-server": {
          "command": ["haskell-language-server", "--lsp"],
          "scopes": ["source.haskell"],
          "syntaxes": ["Packages/Haskell/Haskell.sublime-syntax"],
          "languageId": "haskell",
          "enabled": true
        },
    }
   }
   

4. Close the editor and re-open it in the project folder

   cd <your-projects-dir>
   subl .
   

   Note: if you're using nix-shell, make sure to run it first.

If everything is fine you should get auto-completion and other features working 🎉
