Having multiple Git repositories

Question

This seems like the simplest Git question, but I can't find ANYTHING on it.

So for a newbie to Git, I know how to add, commit, and then push files to my GitHub account. But how do I then create a new project and switch between working on that repository and my old repository? Will cd'ing to the appropriate directory and then remote adding each time work, or could I just cd and push immediately? That seems really tedious. I think I'm missing a fundamental point of Git.

Answer 1

A git project is fully self-contained within its root directory, so cding to another directory with its own git project is switching to another project.

As to the Github part:

Github hosts a copy of the repository for each project, so it makes sense that you have to setup the remote links for each project - they have nothing in common with each other, so they each need the remote link to the repository on Github.

Answer 2

It's just as everyone else described it. A git project contains all sub-directories and files in the directory that has the .git folder (well, all the files that aren't ignored, anyway). There are times, however, when you'll want to have a git repository inside another one though. The way to go about this is to use submodules.
