+# t5de-hub
+
+T5DE's hub (see docs/design.md, a draft under discussion with the user). Related repositories, usually checked out
+beside this one: `t5de` (patches), `t5de-proxy` (local proxy), later `t5de-catalog` and `t5de-api`.
+
+## Rules
+
+- Never commit IMVU's code or captured traffic with account data. Our own declarations of IMVU's protocols and notes
+  in our own words are fine.
+- Test with a throwaway IMVU account, never a real one.
+- Commits: author "dhkatz <dev@t5de.dev>"; never the user's real name or email.
+- The user prioritizes backend performance (Go), and wants moderation centered on the hub's website.
+- IMVU session keys never leave the user's machine; the hub never asks for them.
