About

We are a team working on creating haskell-language-server which is the standard LSP server for Haskell. 

This summer there is a team of us all concentrating on working on the project so that hopefully by the end of the summer the Haskell interactive experience is fast, robust and easy to use.

Now you can also do your part by contributing through OpenCollective. The funds will be used in order to incentivise important work on the project and as an additional source of funding for developers not already funded.
