+**Protip:** You can use `soroban completion` to generate shell completion for `bash`, `elvish`, `fish`, `powershell`, and `zsh`. You should absolutely try it out. It will feel like a super power!!
+
+To enable autocomplete in the current bash shell, run:
+
+```bash
+source <(soroban completion --shell bash)
 ```
 
+To enable autocomplete permanently in future bash shells, run:
+
+```bash
+echo "source <(soroban completion --shell bash)" >> ~/.bashrc
+```
+
+Users of non-bash shells may need to adapt the above commands to suit their needs.
