so what would the experience be for someone new joining the project, particular if you have many repositories? having to search across numerous repositories? In practice I've found this (source control commit messages as ADR's) doesn't work. Unless I have mistaken what you have said? I just keep a repository for ADR's, which can then be published to a wiki or else where.
- your centralised wiki lists all the repositories and explains what they’re for;
- each repository has a detailed commit history, allowing you to understand the thinking behind each line of code.
Edit to add: you can search across multiple repos with Github’s “search in organization” feature, and it actually works very well. I usually find that much more useful than searching through a wiki that’s separate from the code (although maybe I just haven’t ever seen a wiki that was sufficiently well organized?)
