Drew Furgiuele explains the process of contributing to an open source project, specifically dbatools:
Step 2: Check out the Github project page what’s in development.
Next, you should visit the project issues page. Here, you’ll find a list of all the features requested, in development and completed on the project. You can also filter the pages to look at current bugs or requested enhancements. Once you see what’s what, if you think of something you want to work on or help with, make a note of it. You should also look at examples of things in development and things that have been completed so you get an idea of the creative and technical process that goes into the project.
Step 3: Speak up!
Head on back to the Slack channel and let everyone know you want to help out. Someone (probably Chrissy) will add your Github account to to the project as a contributor so you can have things assigned to you. Congrats, you’re now on the hook!
I’m happy that the dbatools community has sprung up and hope it’s a gateway to further open source development in the SQL Server community.
