Right now we have: https://github.com/WebKit/WebKit/wiki https://trac.webkit.org/ https://webkit.org/getting-started/ https://github.com/WebKit/WebKit/blob/main/Introduction.md Brandon’s solution is designed to replace the first 2, and he has buy in from the maintainers of the first two, when his solution is deployed, our existing wikis will die. I think https://webkit.org/getting-started/ and https://github.com/WebKit/WebKit/blob/main/Introduction.md are both designed to be too narrow to be a dumping ground for all our documentation. >> >> Ryosuke: Your document is outstanding, and is a large part of the content we >> pulled into the current repo.

Mixing together documentation commits with commits which change product code is not great, it makes tracking down regressions more difficult for the same reasons we like monotonically increasing commit numbers. I think this is a trade off well worth it for Introduction.md, but not for something like https://github.com/WebKit/WebKit/wiki/Source-Control#identifiers. It’s also worth calling out that Jon Davis and I have had a similar discussion about https://github.com/WebKit/WebKit/tree/main/Websites/webkit.org, that’s probably something we shouldn’t be committing to the same repository with all our product code. > > (2) is particularly important because many people who are new to WebKit often > don?t know what they don?t know.

We have many things which need to be documented that should not be in Introduction.md, though. An example I know I’ve dealt with recently is the management of EWS bots. This isn’t something that belong at the top-level of the WebKit repository, but it’s clearly important.

That very much depends on the section of Trac’s Wiki you’re looking at. https://trac.webkit.org/wiki/TestExpectations is ancient, but pretty accurate, for example. Same for https://trac.webkit.org/wiki/LayoutTestsSearchPath (despite the references to ancient MacOS versions). We need to do some serious clean up (which probably involves a lot of deletion), but blind deletion seems unwise.
