Scenario 1 - Sharing a new project
You make a new project on your computer that you want to save to GitHub
Remote repos
Sharing your version history through a server
Remote repositories in Git are repositories stored elsewhere than on your computer, usually on a site like GitHub or a private enterprise server for your company. Remote repositories have a few key purposes:
- Remote repositories are the mechanism by versions can be shared between computers, e.g., between a lab and home computer or between the computers of multiple teammates collaborating on code.
- Remote repos maintain a copy of your version control history so that if disaster strikes your computer, you have a backup of your project.
Remote repositories are a hub to which multiple local repositories are linked. They function the same as a local repo, but the user takes extra steps to share changes with the remote and to retrieve changes, perhaps made by teammates, from the remote.
git push
Manually sending changes from the local to the remote
Scenario 2 - Clone an existing project
The remote already exists and you want the project
Scenario 3 - Retrieving changes
