A the title says this is a starting point for building a Go on the Intel Edison using resin.io.
The project uses the awesome GB tool to build and package the project
within the Dockerfile. This way all the dependencies are built along with the source.
To include a dependencies all you need to do is add the source of that dependency
in the vendor/src folder and import it in your Go code. In this example we import
github.com/gorilla/mux.
The example code itself is very simple and just runs a basic server on port :8080.
With this as a starting point you should be able to build a whole myriad of Go powered IoT devices. Have fun!!
