+Typically, you'll want to start by creating an account on Docker Hub (if you haven't

+already) and logging in. You can create your account directly on 

+[Docker Hub](https://hub.docker.com/account/signup/), or by running:

+

+    $ sudo docker login

+

+This will prompt you for a user name, which will become the public namespace for your 

+public repositories.

+If your user name is available, Docker will prompt you to enter a password and your

+e-mail address. It will then automatically log you in. You can now commit and

+push your own images up to your repos on Docker Hub.

-## Private Repositories

+### Private Repositories

 Sometimes you have images you don't want to make public and share with

 everyone. So Docker Hub allows you to have private repositories. You can

 sign up for a plan [here](https://registry.hub.docker.com/plans/).

 them only with members of your organization or team. Docker Hub lets you
