Make sure that your operating system is updated!

  • Install Git

Depending on your operating system you install or upgrade git differently, so follow the steps in the link below until you have an updated git version

Setting Up Git | The Odin Project

git --version
  • Configure Git
git config --global user.name "Your Name"
git config --global user.email "yourname@example.com"

Set default branch to main

git config --global init.defaultBranch main

See if you already have a SSH key

ls ~/.ssh/id_rsa.pub
  • Generate a SSH key
ssh-keygen -C <youremail>

When it prompts you for a location to save the generated key, just push Enter.

Next, it will ask you for a password; enter one.

cat ~/.ssh/id_rsa.pub
  • Configure Github

After you created your github account, follow these steps:

  1. Copy that text from ssh to the end of your email address
  2. Go to github.com/settings/ssh
  3. Click on the green button New SSH key
  4. Fill in the Title with your computer name (Macbook Pro for instance)

Two ways to get a folder:

  • Clone it
git clone
  • Make your own folder
git init

Other useful commands

git commit → saves the file or files added. You also put a -m " " to put a message explaining your changes

git log → shows you all the commit history in the folder

gst → git status shortcut

Remote basically means somewhere else than your computer where you can save your work. It could be github or any other platform. 

git remote -v tells us the links that any folder or file has

Fork is when you take a folder in github and you make a copy on your online profile. You do it online.

Clone means that you downloaded that folder into your computer

git clone + ssh key → you take the ssh key from your git hub profile and you use it to clone a repository to yout computer

Push is the command to save your work remotely

git push origin main → origin is the nickname of the github repo and main is the main branch

Pull brings the changes online to your computer to update the folder or file where you are working

git pull origin main
