You cannot do this unless you are a registered Github.com user. Therefore your
first task is to create a new Github account.
Solution
Start your web browser and visit Github.com . Follow the link “Sign up for GitHub”.
Fill in the registration form and submit it. When you finish log in using your newly cre-

If you want to use an avatar for your Github account, go to the ht-
tp://gravatar.com website. Create an account in Gravatar.com , upload your
avatar, and associate it with the email you used for your Github account.
When you have finished configuring an avatar on Gravatar.com , go to
Github.com , log out, and then log in to your account again. Your account should
now use the new avatar.
How It Works
The signing-up procedure is trivial and should be easy to use. The point of this recipe is

$ git clone [e-mail]:jquery/jquery.git
fails, producing the following message:
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
This error is produced:
• If you don't have Github account.
• If your account is not configured to use SSH keys.
