The [SDL slide-out navigation pane][1] lets us view multiple SDL applications from the same panel (via the slide out "hamburger" menu).

I see how we can [extend the slide-out navigation Welcome screen][2] ([requires login](http://docportal.sdl.com/sdltridion)) and a recent SmartTarget update shows `Targeting` in the slide-out Navigation in our environment.

Where can I find instructions to show SDL Media Manager for a given SDL Tridion setup?

**Edit**:

Following John's example, I was able to set the following working example for external URLs (example with SDL Live Content).

**Notes**:

 * Attribute `domain` starts with `http://`
 * Attribute `url` starts with `/`
 * I matched `domainId` to the `applicationDomain` node with the matching `id` attribute 
 * Sites that restrict being embedded in iFrames throw an error in the console (`Load denied by X-Frame-Options: http://tridion.stackexchange.com/ does not permit cross-origin framing.`).
