Engaging with the community

LLVM features a set of mediums to engage with the rest of the community. Things such as asking/answering questions, discussing software design, planning the next release, etc., all happen in the open and you can be part of that starting right now!

Join the Discord server at https://discord.com/invite/xS7Z362 (or go to https://llvm.org and click on Discord) to watch and participate in interactions between members and grow into a part of the community yourself. Start by doing things such as asking questions and offering pointers. Slowly but surely, you will gain the confidence and knowledge to engage in deeper conversations.

Similarly, join the Discourse forum (https://discourse.llvm.org/) to get to know what is happening in the project. Start, for instance, with the Announcements channel to see when the releases are coming out or when the next developers’ meeting is being held. Then, dive into the topics that interest you by following the...
