 ## Set up Haskell dev environment
 
+Complete Haskell dev environment consists of Haskell toolchain (compiler, language server, build tool) and editor with good haskell support. The quickest way to get this set up is to:
+
+1. Use GHCup to install and manage Haskell toolchain.
+2. Use VSCode as the editor, with the Haskell extension installed.

 ### GHCup: universal installer
 
 [GHCup](https://www.haskell.org/ghcup/#) is a universal installer for Haskell that will install for you everything you need to program in Haskell, and then will also help you manage those installations in the future (update, switch versions, ...).

 **Visual Studio Code** is a popular choice with well supported editor integration. Install the [Haskell extension](https://marketplace.visualstudio.com/items?itemName=haskell.haskell) and you are all set. It should work out of the box and use your installation of HLS.
 
-Of other editors that have good Haskell extensions, the most popular ones are Vim and Emacs.
+To learn about support for other editors, check out [HLS docs for editor configuration](https://haskell-language-server.readthedocs.io/en/latest/configuration.html#configuring-your-editor).
