Most of the files in public/ are downloaded from various sources. Here is a list of outside libraries:

1. public/js/angular.min.js: Minified angular.js 1.2.9
2. public/js/less.min.js: Minified less compiler, because this is not intended to be used with any type of production code. Since it's only intended to be run as a demo on a development server, it just uses the javascript client-side less compiler.
3. public/js/bootstrap*.js: Bootstrap javascript files.
4. public/less: Bootstrap less files.
5. public/fonts: Bootstrap fonts.
6. public/partials: Bootstrap html files (I wasn't paying too much attention to their contents, which might not have been a good idea ... I'll clean them up if I ever add real partials).

The main files that make up the demo are:

1. Any file that ends in .go: These are the Go source files for the API.
2. public/app.html: The main html file, which static.go maps all unknown paths to.
3. public/js/app.js: The angular controller that handles the demo.

Pretty standard for a Go project:

1. Install the Go tool
2. Create a directory for Go development, e.g. $ mkdir -p ~/dev/golang
3. Set up the GOPATH environment variable to point to the above directory, e.g. $ export GOPATH="~/dev/golang"
4. Add $GOPATH/bin to your $PATH: $ export PATH="$GOPATH/bin:$PATH"
5. Run go get: $ go get github.com/nelsam/goweb_angular_demo
6. Run the application: $ PORT=5000 goweb_angular_demo
7. Visit localhost:5000 in your web browser.
