After initialising a new local repo there is a description file present.
What is it used for and how should I format it? Or is it simply a local helper file.
This thread Accessing git’s `description’ file suggests one style, but no man page or other reference to why it should be the way it is.
descriptionfile is only used by the GitWeb program ( to display the description of the repo on the GitWeb page)https://git-scm.com/book/en/v2/Git-Internals-Plumbing-and-Porcelain
Otherwise, how you use it is left to you and I don’t see a point in a “style” for it.
