SUMMARY Once you have given one of the Open Source Licenses to your project you can use quite a lot of tools, services for free. The Open Source Community is diverse and you can become a member. Open Source projects and their developers are visible to the whole community A Pull / Request workflow makes it easy to collaborate. Once requested a review of potential changes can be done. Testing and test coverage is important and saves a lot of time. 250 Issues on the MSS tracker resolved MSS has currently 21K lines of code by 8 authors Member of the Helmholtz Association 2.
