How to use Galeri? Can we have a setup guide?

Is your feature request related to a problem? Please describe.
When someone downloads and installs Galeri for theset-up time (like me), they have no clue how to use it. A set up direction would be great. The application is in my Applications, but clicking on it doesn't do a thing. How to change my background?

Describe the solution you'd like
A clear and concise FAQ on how to install and use it. Maybe, even with other feature details. It can be hosted as a GitHub Wiki, with links on the website.

Describe alternatives you've considered
Maybe a screencast on YouTube would also be great.

Additional context
Nothing specific.

Hello! Unfortunately there's currently no working version of Galeri. If I get enough time I'm going to attempt a re-write in the next few months, and will update this issue once there's a working download link.
