Contributing to Geant4

To contribute patches to Geant4, users can submit normal GitHub Pull Requests (PR) such that:

• A single PR refers to a single particular topic (fix or suggested enhancement); PRs including uncorrelated changes in codes in different areas or modules will not be considered.

A PR will be examined by a responsible and eventually extracted for a patch in the development repository of Geant4, to be included in a future release or patch.

For simple bug-fixes, it is still recommended to use the official Bugzilla problem reporting system to report the issue, linking back to the Pull Request if created:

• Problem reports: Bugzilla problem reporting system.

Questions on Geant4 itself or feature requests should be made through our User Forum, and full documentation on use of the toolkit is online.
