+    - The first time you run dockerized, it will compile itself.
+      - Compilation is done within docker, no dependencies needed.
+    - To re-compile after changing the source code, run:
+      - `dockerized --compile` (runs within docker)
+      - `dockerized --compile=host` (runs on your machine, requires Go 1.17+)
+    - You do not need to re-compile to add commands. See [Add a command](DEV.md).
