I worked on the documentation of the Plone add-on ‘collective.addons‘ in my spare time during the last two weeks. I finished this user documentation some days ago and compiled a version in HTML file format and in the pdf file format. I also worked on the Python modules of the Plone add-on and got its build on Travis-CI ‘green’, thus it builds without issues and didn’t throw any flake8 errors anymore.
I published the first stable release of collective.addons on the ‘Cheeseshop’ (Pypi.org) today: https://pypi.org/project/collective.addons/. The add-on provides an ‘Add-on Center’, where contributors could create add-on or extension projects and publish their releases (especially Free Software releases). The Add-on Center make it possible to adapt it to nearly any software project. For detailed information have a look into the user documentation on Github: https://github.com/collective/collective.addons/blob/master/docs/collective.addons.pdf
