+[Radicle CI broker]: https://app.radicle.xyz/nodes/radicle.liw.fi/rad:zwTxygwuz5LDGBq255RA2CbNGrz8
 
+This crate also includes the program `rad-ci`, which runs the commands
+the adapter runs when invoked by the CI broker. To use: install it on
+your `$PATH` (using `cargo install`) and run:
+
+```sh
+rad ci
+```
+
+This will read `.radicle/native.yaml` and run the shell commands
+specified there.
+
+(No command line arguments or options needed, nor any environment
+variables for this.)
