See JabRef's contribution guide for a howto to contribute code.

In case you aim for contributing user documentation, head to the JabRef user documentation repository.

For improving developer's documentation, go on at the docs/ subdirectory of JabRef's code and edit the file. GitHub offers a good guide at Editing files in another user's repository.

In case you use some gitbook special features and you want to test them, checkout JabRef's code locally, and execute following steps:

  1. npm install -g gitbook

  2. cd docs

  3. gitbook serve

Then, you can see a near-to-reality rendering of the development documentation at http://localhost:4000.
