    SSH keypair setup for GitHub (or GitHub/GitLab/BitBucket, etc, etc)

Create a repo.

Make sure there is at least one file in it (even just the README.md)
Generate a SSH key pair (private/public):

ssh-keygen -t rsa -C "your_email@example.com"

or even better:
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

It also possible to use ed25519. There are pros and cons, but personally I've had some issues and that is the reason I've chosen to stick to 4096 rsa for now.
Copy the contents of the public SSH key

macOS:
pbcopy < ~/.ssh/id_rsa.pub

GNU/Linux (requires the xclip package):
xclip -sel clip < ~/.ssh/id_rsa.pub

Windows Command Line:
type %userprofile%\.ssh\id_rsa.pub | clip

Git Bash on Windows / Windows PowerShell:
cat ~/.ssh/id_rsa.pub | clip

or ofcourse copy it via your favorite editor, cat, or whatever suits your needs :)
Copy the public SSH key to GitHub

Copy the contents of the to your SSH keys to your GitHub account settings (https://github.com/settings/keys).
Test the SSH key:

ssh -T git@github.com

Change directory into the local clone of your repository (if you're not already there) and run:
git remote set-url origin git@github.com:username/your-repository.git

Now try editing a file (try the README) and then do:
git add -A
git commit -am "Update README.md"
git push

Add the key to the ssh-agent
ssh-add ~/.ssh/id_rsa

You should not be asked for a username or password. If it works, your SSH key is correctly configured.
