We're always looking for people to help make Lidarr even better, there are a number of ways to contribute.
Setup guides, FAQ, the more information we've got on the wiki the better.
Lidarr is written in C# (back end) and JS (frontend). The back end is built on the .NET6 (and soon .NET8) framework, while the frontend utilizes Reactjs.
Please see CONTRIBUTING.md for details.
