This guide is for developers who are working on the various Zope-related software projects, rather than for developers who work with those projects’ released software to build applications. Developers in the latter category should visit the general Documentation section instead.
The projects under the zopefoundation GitHub organization are open source and welcome contributions in different forms:
code improvements and bug fixes
pull request reviews
For any changes in the repository besides trivial typo fixes you are required to sign the contributor agreement. See Becoming a Contributor for details.
Visit https://github.com/zopefoundation to see and browse all repositories maintained by the Zope developer community.
The overview at https://zope3.pov.lt/py3/gha.html lists the supported Python versions and the build status for all Zope Foundation projects (the overview is not guaranteed to be complete and accurate).
