After installing RegistryUI in Docker, the first time you connect to it, you will be prompted to create the first user account. This first account is an Administrator account. This account can create groups, users, projects and repositories and perform all administrator functions.
Enter the desired user name. The default is "admin".
The email address should be valid as it is used for password recovery in case you misplace the password. You can reset your account by receiving an email at that email address with a reset link.
The password must be entered twice for verification.
Once the form is completed click Save to create the new account. This account (user name, password) is available on this instance of RegistryUI. The RegistryUI.com site doesn't use this account information.
After creating the new account, the following page is shown, inviting you to enter the subscription information.
