For a new project at home, I set up a local git repo. One I feel
the basics work, I'll move it to github.

For projects on github, if the code is in a lot of flux while I am
in the middle of <laughing> designing it, I use a dated zip file
to hold changes until I get to a point of metastability (the code
builds and basically runs, usually some issues to work on).
Then I'll do a commit.

Been burned by the zip method a few times :-D
