+### Developing
+To support the development of the application, a few extra tools have been built, the most useful one being `dev-proxy`.
+This script, located in `scripts/dev-proxy`, is invoked without any parameters (to simplify daily usage) and all its configurations are hard coded into the actual code it executes: `scripts/proxy/main.py`.
+
+The aim of this proxy is to mask the actual location of frontend JS files from the actual backend handling requests.
+
+When executed, this script will start listening on localhost:8888.
+
+All 'backend' requests (whose path starts with either `/json` or `/dump`) will be forwarded to the actual backend, that is configured as a `ReverseProxyResource` (in the current code: `proxy.ReverseProxyResource('localhost', 8084, '/java-backend')`).
+All other requests (html files, Javascript code, CSS stylesheets and other resources) will be handled by reading the resource from the filesystem; the proxy is aware of the layout of the project, so it will be able to locate the right resource in the right place.
+
+The only file that needs to be `build`, and not read directly from the file system, is the `index.html` file.
+
+In order to build this file, the following command should be executed:
+
+	./scripts/build --frontends beta gamma gamma.mobile --backends dev
+
+
+Once the index.html files have been built (one for each frontend) and a backend is running and has been correctly configured in the proxy script, it is possible to access the different versions of the application at the following URLs:
+	- `http://localhost:8888/beta/index.html`
+	- `http://localhost:8888/gamma/index.html`
+	- `http://localhost:8888/gamma/index.mobile.html`
