I found some documentation about PWB on Wikiversity and Wikibooks: https://en.wikiversity.org/wiki/Pywikipediabot https://en.wikibooks.org/wiki/Pywikibot They're mostly obsolete, and should redirect to the up-to-date manual on MediaWiki.org. But since the license allows it, we can copy some content from there ;-) https://www.wikidata.org/wiki/Wikidata:Creating_a_bot#Pywikibot is somewhat newer, but still duplicates MW.org.
