A quick primer on GitHub

GitHub, and the language Git, are collaboration tools for software engineers and data scientists that provide a framework for version control. We do not need to know everything about how they work to use Streamlit Sharing, but we do need to be able to create our own repositories (which act like shared folders) and update them as we update our applications. There are two options for dealing with Git and GitHub, via the command line and via a product called GitHub Desktop. Primarily in this book, so far, we have stayed on the command line, and this tutorial will stick there. However, if you would like to use GitHub Desktop instead, head over to https://desktop.github.com and follow along with the instructions provided there. 

Now, use the following steps to get started with Git and GitHub on the command line:

1. First, go to https://www.github.com and make a free account there.
2. Then, we need to download the language Git onto our own computer...
