Developing HOL

As git is a distributed version control system, it is easy for you to make your own local commits to your copy of the repository. If you’d additionally like to have those commits incorporated into the official repository, you need to issue what is known as a “pull request”. You will first need to push your version of the repository onto GitHub (which you may already have set up if you forked our code there). Then you follow the process described here (GitHub documentation). Developers might like to subscribe to the developers' mailing list in addition to the hol-info users' list.
