 If you have a [python3-pip-skeleton](https://github.com/DiamondLightSource/python3-pip-skeleton) based project then it is best to adopt the `1.0.0` release of this template, then `copier update` to get to the latest. This is because `copier update` will try and merge file changes across renames done between releases, while `copier copy` cannot. This looks like:
