+
+## Get Started
+html-battle is based on [Node.js](https://nodejs.org/) and uses [npm](https://www.npmjs.com/). Make sure you have installed it.
+
+Once you have cloned `html-battle`, install the packages by running
+
+```bash
+$ cd html-battle
+$ npm install
+```
+
+You will notice a new directory `node_modules` containing the installed packages. Next, you may have to install the dependencies using [Bower](https://bower.io/) (which has been installed in the previous step). Therefore, run
+
+```bash
+$ cd public
+$ bower install
+```
+
+Finally,
+```bash
+# Start the server, e.g. node server.js -p 8888 -h localhost
+$ node server.js [-p <port>, default: 8080] [-h <hostname>, default: 192.168.178.55]
+```
+will start the server on the given `port` and `hostname`.
