 Doesn't look fantastic at the moment, so feel free to submit a pull request where you just rm -rf. (That probably won't be approved, but a UI improvement would be much appreciated).
 The license is what is says on the tin, fork off and have fun with the code.
 
+## Local development

 To run it locally:
 
 ```bash
 yarn
 yarn start
 ```
 
+## Disclaimer

 As always, be extra careful when downloading and running scripts from the internet. Even though all this does is make silly git repositories for you to ruin your git contribution board, and the source code is available here for you to scrutinise, you should **always** read through any script you download before you run it.
