I know Introduction.md is contentious (https://bugs.webkit.org/show_bug.cgi?id=217017), but I figure we can move the docs added in this patch elsewhere later if we want.

FWIW, I find Introduction.md to be really helpful (though I am not the targeted first patch audience anymore).  Usually I open it with an easily Ctrl-F'able purpose ("How does logging work?").  This workflow might be a little bit harder if things were split up.

Yes, the first thing to do is to move all the necessary information in this document. We can then decide whether splitting up is the right thing to do. Given how bad existing documentation on websites and wiki have gotten, I'm skeptical of that approach. The issue is that nobody would remember to update all the places documents are out of date because it's so hard to find all the references to a given concept, policy, or process.

Right. In fact, Introduction.md is really meant for anyone contributing to WebKit who needs to figure out how to do certain things or venturing into new territory. e.g. if you had never written ref tests, there is explanation for that. If you had never dealt with GC, then there should be a section about that too. As you touch on more areas & technical concepts in WebKit, you should be able to go back to this intro doc to learn the basics.
