1. Download latest binary for your platform from GitHub releases

2. Run it from Terminal or Command Prompt

   Optionally you can run it with -h flag to see what can be configured.

3. Set Application URL for device in Visionect Server to http://<server_address>:<server_port>/screen (default port is 4000)

4. You can use http://<server_address>:<server_port>/screen?x=<offset_x>&y=<offset_y> to display only a part of the screen. This enables you to tile multiple displays together and designate one to display a certain part of the image. The parameters disable the automatic image scaling.

The whole backend is written in digitalsignage.go. It contains RESTful(ish) API for uploading, removing and selecting images. It also contains a template view that will display the current image.

We use bindata to package static files in the binary. For faster development you should use make debug that will only link files and not embed them in the binary (so you don't need to recompile every time you change files in static folder).

Front end is done with Polymer. Everything custom is in files static/index.html and static/elements/visionect-images.html.
