git | tag with annotation

I always want a long description for my git branch. Not sure how best to do it. https://stackoverflow.com/questions/4750845/how-do-you-annotate-a-branch has some suggestions.

— Git tag can have an annotation:

git tag -a newTag some_commit #create
git show newTag #reveal the annotation, creation time etc
git tag -d newTag #deletes the tag

Two ways to edit annotation:

1. We can remove and re-tag with a modified annotation.
2. git tag <tag name> <tag name> -f -a
