### Querying the engine via the website
You can query the engine by going to [the HTML page itself](http://127.0.0.1:9700).
## Contributing
You can setup a `git-hook` to stop you from making a commit too fast. It'll stop you if:
- Any of the workspaces does not build
- Your code is not well-formatted
These two things are also checked in the CI, so ignoring the hook won't help you merge your code.
But if you need to, you can still add `--no-verify` when creating your commit to ignore the hook.
To enable the hook, run the following command from the root of the project:
```
cp script/pre-commit .git/hooks/pre-commit
```
