Start here and follow the links, including to the project ideas page and the PR database (bugzilla):

Get involved in the mailing lists, try things out and see what interests you. If you find (or fix!) bugs, submit problem reports to Bugzilla. You can also contribute patches to existing PRs.

As mentioned you can use Bugzilla to submit problem reports and patches. You can also use it to submit new ports.

The mailing lists are appropriate for discussion of new features and small patches. Larger patches can be submitted to Phabricator ( for review. Phabricator is also a good place to look at other work in progress.

The official FreeBSD code repositories are Subversion, but there is a growing number of people using git. There are now official github repos for FreeBSD, which are updated regularly from the SVN repos:
