git config --global user.email "YOUR_EMAIL"

Create a New Repository on GitHub

Create a new repository from the GitHub web page of your account.

Set Up SSH Keys

To authorize GitHub, it is recommended that you set up SSH keys on your PC and add them to your GitHub account.

ssh-keygen -t ed25519 -C "YOUR_EMAIL"

To connect to host github.com the following is usually used

ssh -T [email protected]

If you had some issues or timeout errors it is may be due to the related wifi connection try to change the wifi connection, if still or no other internet source available try the following commands:

ssh -vT [email protected]
ssh -T -p 443 [email protected]

Please see the SSH keys subtitle below for instructions.

Initialize a New Repository Locally and Push to GitHub

After setting up your SSH key as explained, follow the steps below to commit the changes and push them to GitHub:

To Create a New Repository on the Command Line

echo "# test3" >> README.md
git init
git add README.md
git commit -m "first commit"
git branch -M main
git remote add origin [email protected]:USERNAME/YOURREPONAME.git
git push -u origin main

echo "# test3" >> README.md: Creates a README.md file with the text "# test3". This is typically done to initialize the repository with a readme file.
git init: Initializes a new Git repository in the current directory. This creates a .git folder to track all changes.
git add README.md: Adds the README.md file to the staging area.
git commit -m "first commit": Commits the changes in the staging area with a message "first commit".
git branch -M main: Renames the current branch to main.
git remote add origin [email protected]:USERNAME/YOURREPONAME.git: Adds a remote repository called origin pointing to your GitHub repository.
git push -u origin main: Pushes the changes to the main branch of the remote repository and sets the upstream tracking for the main branch.

To Push an Existing Repository from the Command Line

git remote add origin [email protected]:USERNAME/YOURREPONAME.git
git branch -M main
git push -u origin main

git remote add origin [email protected]:USERNAME/YOURREPONAME.git: Adds a remote repository called origin pointing to your GitHub repository.
git branch -M main: Renames the current branch to main.
git push -u origin main: Pushes the changes to the main branch of the remote repository and sets the upstream tracking for the main branch.
