Local/Remote Image Templates

In general, there are two separate repositories. The first one is the local repo, where the local image templates can be found and are immediately available for use.The second repo is the remote repository (offered by Sunlight.io) which contains the image templates that are stored in a cloud repository and can be downloaded locally by the user.

As the images below illustrate, in the Local repo all distributions are indicated as Local in contrast to the Remote repo where templates are indicated as Remote and could be downloaded locally for use.
