There is a well-done video on Git and Github on YouTube, link below.
Here are a few notes before you watch the video.
The video concentrates on the use of Git / Github for programmers, but all the same things apply to scientists and academics writing collaborative projects and papers.
It starts very basic, but bear with, it quickly gets on the specific stuff we have not covered elsewhere, on using Git with Github.
The author is using the old-style default branch naming in Git, where the default branch is called
master. The default branch, for modern Git, is now called
main. Just read
I would set up your Github account with an SSH key following the Github instructions before you start the video. Although the video suggests that having no passphrase for your SSH key is OK, we would not recommend that. We suggest you do in fact have a reasonably long (but memorable) SSH key passphrase.
The video starts using the terminal from within VSCode. The author says this later, but this is just the same as using terminal outside VSCode, so if you are not using VSCode, just type the same commands in the terminal. In fact, I would recommend using the terminal outside VSCode even if you are using VSCode, at least at first.
The video uses the
-m flag to
git commit to provide a commit message and maybe a description. We suggest you don’t do that, and you set up your editor to work with Git, so when you type
git commit, Git will open your editor for you to type a message. See below for how to do this.
The usual default editor for Git is Vim, so if you want that, you don’t need to change anything. If you don’t then:

To make sure you understand most of the material in the video, do the following:
- Fork the repository at https://github.com/nipraxis/first-pull-request using the “Fork” button towards the top right.
- Clone your fork of this repository to your computer.
- Make and checkout a new branch called
- Make the changes given in the instructions at the top of the
git addthese changes, then
git committhe changes.
- Push the changes from this branch up to your fork. Make sure you are pushing the new branch.
- Do a Pull request from this new branch to the original (base) repository
masterbranch at https://github.com/nipraxis/first-pull-request
- We will review your pull request!
Markdown is the standard way of writing nicely formatted text on many platforms, including on Github, and in the Jupyter notebook. You will see it in many places, and you will find yourself using it often — for example, in Jupyter text cells. Get used to writing Markdown by doing the Markdown tutorial.
