Where can I start commiting in engine sources?

Hello.

UE4 is first open source project I interested in. So, here is the question - how and where can I start my work on it’s sources? Should I just choose bug in issues tracker and start working on it or do I need to tell someone what I want to fix? Where can I find something about workflow on UE4 sources?

English isn’t my native language, so forgive me my mistakes, if you find ones.
Thank you in advance!

Hey there to find the engine source code you just go here (you must be signed in). After that you pull a version of the code and then if there is something you want to improve you do a pull request, that you can find out about it here.

Thank you! Now I got how it works c:
