Do not "hack the core". If you have any issues with **Cupper**, please report them to [the **Cupper** Github repository](https://github.com/ThePacielloGroup/cupper/issues) and they will be dealt with ASAP.
Cupper is undergoing constant development, so keep an eye out for new releases. To update to a new version of **Cupper**, simply run the `update` command from inside your local project folder.
This will save a timestamped backup of the current version, and download the latest version. Your theme folder will now look something like the following.
If you experience breaking changes and are having trouble fixing them, you can rename the old folder and revert to using it. In the meantime, you can [submit an issue](https://github.com/ThePacielloGroup/cupper/issues) with the "help" tag describing your problem.
The described update process relies on SVN because Github does not support downloading individual repository folders. If you have a Mac, SVN should be installed already. If not, or if you are on Windows, you can either install SVN or download the latest [**Cupper** theme folder](https://github.com/ThePacielloGroup/cupper/tree/master/themes/cupper) manually, using the Github web interface.
