Description of feature

As discussed in Slack (this and following posts) the option to create workflows without using git will be removed if no compelling use cases come to our attention.

Quote from @ewels about how the git-less creation came to be:

I think it was requested for people who had already initialised a git repo themselves previously
But it's generally A Bad Thing, as the fresh repo is needed for automated template synchronisation
