History cleanup is project about adding/removing information into "History" section, that can be found in almost all pages about blocks, entities, etc..
Why?[]
"History" sections in pages usually have lack of information. Also, some pages have wrong information in it (for example bad version).
How to help?[]
Firstly, add your signature to the members list below using ~~~. Then open article about some version which is not in "Checked Versions" category below and look over the page. When you find some change/bug fix/addition, see if the information is also on the "History" category about the thing. It's also recommended to check official patch note or test it to prove if the information is true. However, if there is missing information about bug fix, add information and then add link after it redirecting to the bug tracker using <ref> (also if there is no "References" category, add it and then add {{Reflist}} in the "References" category). Also, if there is false information, remove it/correct it. Then, add it into "Checked Versions" category below. If you don't know how to use history template, see Template:History.
