DevelopersHandbook's Shadow on the Wiki

As I have stated elsewhere before, wikitext, or rather wiki pages, cannot be converted to markdown because they have much richer content (templates, etc.). However, the opposite is very possible. Accordingly, a shadow of the DevelopersHandbook repo can be created on the wiki. So the pages here are transferred to the wiki regularly. In the wiki, these pages are closed for changes to prevent problems. In this way, integrity is ensured in the documentation ecosystem. It is also preserved in two places. It also has the better aspects of the wiki, such as translation and API.
