This demo users angular, ng-flow-standalone, boostrap and the demo application from the ng-flow github repo: https://github.com/flowjs/ng-flow/tree/master/samples/basic
This is only needed if you mess with the static assets embedded in the demo, which probably isn't worth it anyway.
prompt: go get https://github.com/jteeuwen/go-bindata prompt: $GOPATH/bin/go-bindata html/...
The output will be a fresh new bindata.go with the static assets inside of it -- then you can recompile and enjoy.
