Once you have all the information about the available locations, you can check out the name of existing registries. The name you choose should be available and must not be already in use.
Note:
Your chosen name must be available for the registry.
All registry names must be unique.
Make sure the name is suitable for use in the new registry: it only uses the characters "a-z", "0-9" or "-", starts with a letter and ends with a letter or number, and can be from 3 to 63 characters long and is accessible.
You can retrieve all the existing registries to check out the available names.
