Install a development environment

To work on GitLab itself, we recommend setting up your development environment with the GitLab Development Kit. If you do not use the GitLab Development Kit you need to install 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 the getting started section of the GitLab Development Kit.
