Hi!

Rocket.Chat is built using modern JavaScript/TypeScript technologies, so editing it directly requires a bit more familiarity with the codebase and those technologies ([https://github.com/RocketChat/Rocket.Chat/](https://github.com/RocketChat/Rocket.Chat/))

If you want to help developing, we have a great channel for receiving new coming developers:

If you want to customize it, there are some tools that will help you on that.

Thanks and welcome 🙂
