+`racket-langserver` is a [Language Server Protocol](http://langserver.org/) implementation for Racket. This project seeks to use [DrRacket](https://github.com/racket/drracket)'s public APIs to provide functionality that mimics DrRacket's code tools as closely as possible.
 
-## Installation
+## Installation and usage
 
-Install via the command line with `raco pkg install racket-langserver`
+A Racket runtime is a prerequisite, so before using `racket-langserver`, ensure that a Racket runtime is installed. You can install an from the [official download page](https://download.racket-lang.org) or install one from your package manager.
 
-If you plan on using this package with Atom, you should install [atom-ide-racket](https://github.com/cfinegan/atom-ide-racket) instead. This package will be installed automatically by the *atom-ide-racket* installer (although the Racket runtime should be installed prior to this).
+### Atom
+
+You can use the [atom-ide-racket](https://github.com/cfinegan/atom-ide-racket) package. The language server will be automatically installed when `atom-ide-racket` installs.
+
+### Other editors and IDEs
+
+First, install an LSP runtime for your editor.
+
+Next, install the package via `raco`:
+
+```
+raco pkg install racket-langserver
+```
+
+Once it is installed, you can configure your editor to use a custom LSP client for Racket files (`.rkt`), and set the command for the custom client to
+
+```
+racket -l racket-langserver
+```
+
+You may need to restart your LSP runtime or your editor for `racket-langserver` to start.
