I apologize in advance for being such a pain-in-the-neck, but could you add links to the contribution guides in the future? The core contribution guide is linked from team page on forge, but still might be useful to include a link to it directly on this page.
For core: https://docs.typo3.org/typo3cms/ContributionWorkflowGuide/
for docs: https://docs.typo3.org/typo3cms/HowToDocument/WritingDocsOfficial/Index.html
You could alternatively link to docs team page but that is currently outdated, so I think linking to contribution section is better choice.
