Hey everyone, I’m happy to announce that we’re now accepting OSS contributions to the Mojo compiler and tools! We are starting slowly, with bug fixes accepted first, and we will gradually work towards taking more substantial contributions. Please go ahead and start opening the PRs! Here are some [good first issues](https://github.com/modular/modular/issues?q=state%3Aopen%20label%3A%22good%20first%20issue%22) to get you all started. And here are the [contributing guide](https://github.com/modular/modular/blob/main/Mojo/docs/contributing/README.md) and some [helpful details](https://github.com/modular/modular/blob/main/Mojo/docs/contributing/contribution-areas.md). Looking forward to working together with all of you! – Mojo Compiler team ---

Worth noting that we’re all at a company offsite next week so will appreciate your patience on any PRs that you put together! Please keep in mind our new [issue and PR etiquette guide](https://mojolang.org/community/contributing/issue-pr-etiquette/) when making contributions. We’re all getting to grips with AI tools but need to be mindful of the burden we place on others if we don’t take the time to clean things up 🙂 ---
