Bot documentation on English Wikipedia: https://en.wikipedia.org/wiki/Wikipedia:Bots has a nice flow to it. The sections are well-explained, it's "How to create a bot" section also points to a thorough guide and lists Pywikibot framework, but this document is specific to English Wikipedia (especially the policy and the approval process listed on it).
And, then we have https://meta.wikimedia.org/wiki/Bot and https://www.mediawiki.org/wiki/Manual:Bots which seem to be incomplete or lacking a structure. Probably, both the docs should be linked and have the same information. The intended audience for this doc should be all Wikimedia wikis, both bot users and developers, etc.
This task would require someone to review all the three tutorials and use the good pieces from English Wikipedia to improve the other two. For example, in the doc on meta-wiki, the "Frameworks and interfaces for bot development" section could be reviewed to ensure that all the frameworks listed are still used/useful. The section "Current and proposed bots" feels unnecessary and it is also missing the bot creation process.
