GitHub is a website that lets you post your code so you can keep it organized and share it with other people. It’s a little bit like social media for coders, and it’s a great way to show off your code and to see what other folks are working on.
We’ll be using GitHub to share code with each other. Before you get started, sign up for a GitHub account.
Git is a tool that lets you store your files so you can work from multiple computers, or with other people. It’s commonly used by people working on code projects together, since it lets everybody work with the same files. It’s also handy when you’re working on your own, because it lets you track your changes over time.
Git is a version control system which is a fancy way of saying that Git helps you track different versions of files. If you’ve ever written a paper and then saved a file called
my-paper-final.txt and then realized you needed to change it, so you saved a file called
my-paper-final-2.txt and then made even more changes, eventually saving a file called
my-paper-final-really-final-this-time-3.txt, then that’s another kind of version control system. Git is a way of automating that.
We won’t use Git directly in this class, but I’m mentioning Git because GitHub uses it behind the scenes.
GitHub organizes code into repositories, or repos, which you can think of as a directory full of files.
The Intro to Web Dev repo contains starter code and instructions for each week’s project.
This should create another repo called
GitHub Pages lets you take a GitHub repository and turn it into a website.
Enable GitHub Pages for your project repo. Starting at your repo’s homepage, go to the
Settings tab, and then select
Pages in the left nav.
Source section, select the
main branch. Then click the
When you’re done, GitHub will give you a URL like
YourUsername.github.io/intro-to-web-dev. This URL won’t work yet, but remember it because you’ll need it in a minute.
When you’re finished, continue working through week 1:
