+# Hooks
+
+Each `*.sh` file here runs when the container starts, with your project available
+at `/code`. They run in name order, so prefix them with numbers (`10-`, `20-`)
+to control the sequence.
+
+Because they run every launch, keep them quick and make them safe to re-run —
+check whether the work is already done before doing it. If one fails, startup
+stops rather than continuing half-configured.
+
+Edits take effect on the next launch (no rebuild needed). Rename a
+`*.sh.example` file to `*.sh` to turn it on.
