GitLab is an open source project and we are very happy to accept community contributions. Please refer toContributing to GitLab page for more details.

To work on GitLab itself, we recommend setting up your development environment withthe GitLab Development Kit (GDK).If you do not use GDK, you need toinstall and configure all the dependencies yourself, this is a lot of work and error prone.One small thing you also have to do when installing it yourself is to copy the example development Puma configuration file:

cp config/puma.example.development.rb config/puma.rb

Instructions on how to start GitLab and how to run the tests can be found in thegetting started section of the GitLab Development Kit.
