Add information about publishing an extension to FAQ
There is a page: https://extensions.typo3.org/faq/publish-an-extension/
Can you add an item and link to that page to the FAQ list (preferably at the top)?
It is available in the menu on the top, but that is not the first place I would look.
Also, there is general information about publishing extensions in TYPO3 Explained: https://docs.typo3.org/m/typo3/reference-coreapi/master/en-us/ExtensionArchitecture/PublishExtension/Index.html
