Use actual GitHub alternatives
Hellow! I was rechecking the website and understood that 'GitHub' alternatives do not seem as an alternatives at all...
For example, instead of saying 'Gitea' we could provide an actual working alternative with existing community - Codeberg. Instead of provoding a list of random GitLab instances we could use Framagit as an ACTUAL alternative.
Those lists could be provided in 'Self-host' section so they wouldn't be excluded and would provide information for both sides: amateur and professional developers with their needs.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
