 ## Pull requests
 **Please ask first** before embarking on any significant pull request (e.g. implementing features, refactoring code), otherwise you risk spending a lot of time working on something that developers might not want to merge into the project. To avoid that, you can join the official [Unigram Insiders](https://t.me/joinchat/AAAAAD851oqVwhp9oy9WbQ) group and talk with the team.
