Things we need to document here:

• Creating a new package using the template
  • Install cookiecutter
  • Run cookiecutter
  • Answering questions, what they all mean etc
  • git init
  • How to use the CI configs, RTD and pre-commit
  • pre-commit (it runs as part of tox so needs to be run to make sure it passes).
• Updating a package with a new version of the template
  • .sunpy-template.yml
  • Run cookiecutter --no-input --config-file .sunpy-template.yml
  • review diff, drop some changes, stage others.
  • How to detect files removed by the template?
• Removal of astropy_helpers + upgrade from old templates.
  • https://docs.astropy.org/projects/package-template/en/latest/ape17.html
  • also _sunpy_init.py and other files no longer used.
