 # Jackal EVM Bridge
 
-To start, fill in the `.env` file.
+## Init
+To init your system, you can get a new address like this.
+```shell
+mulberry wallet address
+```
+This will also create the `~/.mulberry` directory and all the config files. You can adjust where this goes with the `home` flag.
+
+## Config
+You will get a new config file that looks something like this, feel free to change out the entries as you see fit.
+```yaml
