You should use git to tag your final project before your Career Day presentations, especially if you plan to continue working on it. This will allow you to go back to the commit you were at for your Career Day presentation. This is especially helpful if you would like to show employers what you've worked on/changed since they saw your presentation.
A tag is kind of like a branch, but unlike branches they’re meant to be static. They’re usually used for releases (e.g. v2.0 for a library like AngularJS).
To make an ‘annotated tag’, (i.e. a tag with a message) run the following command in your project's directory:
git tag -a v0.5 -m 'Career Day’You can then use git push —tag to push your tag up to Github.
