1. Set your username and email address in Git: Setup the Git user details on your machine, which is used as your identity by the Github or other repository providers. To set up a username and email address system-wide, execute the following command. Make sure to change your name and email address with yours.

   git config --gloabl user.name "Your Name"
   git config --gloabl user.email "[email protected]"
   

   To configure identity for a specific repository, remove --global from the above command and run it from your repository directory.

2. Set your default text editor:

   git config --global core.editor vim 
   

   Replace “vim” with your preferred text editor.

3. Generate an SSH key and add it to your GitHub account (or any other Git hosting service you are using):

   ssh-keygen -t rsa -b 4096 -C "[email protected]" 
   

   This will generate an SSH key and prompt you to enter a file to save the key. Press Enter to accept the default file location. Then, it will ask you to enter a passphrase. You can either leave it empty or enter a passphrase, depending on your preference.
