Do you mean your Pulumi.<stack>.yaml? Yes, that goes into git along with everything else. Though since you're talking about provider versions, that's defined by your yarn.lock / package-lock.json (or equivalent for your language). You can choose to version that too, there are arguments both ways on that one.
No matter how you like to participate in developer communities, Pulumi wants to meet you there. If you want to meet other Pulumi users to share use-cases and best practices, contribute code or documentation, see us at an event, or just tell a story about something cool you did with Pulumi, you are part of our community.
