 ## Getting Started
 
+### With packages
+
+##### Using Sensu repositories
+See [Sensu documentation](http://sensuapp.org/docs/0.13/dashboards_uchiwa)
+
 ### From source
 
-* Checkout the source: `git clone https://github.com/sensu/uchiwa.git`
-* Install bower on your system: `npm install -g bower`
-* Install the dependencies:
+**Prerequisites**
+* Recent version of **git**
+* Recent version of **npm** ([guide](https://github.com/joyent/node/wiki/installing-node.js-via-package-manager))
+* Recent version of **go** ([guide](https://golang.org/doc/install))
+
+**Installation**
+* Checkout the source: `go get github.com/sensu/uchiwa && cd $GOPATH/src/github.com/sensu/uchiwa`
+* Install third-party libraries:
+  * With standard user: `npm install --production`
   * With root user: `npm install --production --unsafe-perm`
-  * With normal user: `npm install --production`
 * Copy **config.json.example** to **config.json** - modify your Sensu API information. See configuration section below
-* Start the dashboard: `node app.js`
+* Start the dashboard: `go run uchiwa.go`
 * Open your browser: `http://localhost:3000/`
 
-### With packages
-
-See [Sensu documentation](http://sensuapp.org/docs/0.13/dashboards_uchiwa)
-
-### Use nginx as proxy
-
-The first thing you need is Nginx **1.3.13** or higher, since previous versions do not support websocket connections.
-
-Then, you simply need to open up the Nginx configuration file and add the following route to your virtual server:
-```
-location / {
-  proxy_pass http://localhost:3000;
-  proxy_http_version 1.1;
-  proxy_set_header Upgrade $http_upgrade;
-  proxy_set_header Connection "upgrade";
-  proxy_set_header Host $host;
-}
-```
-
-In case you want the dashboard to be accessible within a certain path on the proxy, let's say /uchiwa, simply use the following block instead:
-```
- location ~ (/uchiwa/|/socket.io/) {
-  proxy_pass http://localhost:3000;
-  proxy_http_version 1.1;
-  proxy_set_header Upgrade $http_upgrade;
-  proxy_set_header Connection "upgrade";
-  proxy_set_header Host $host;
-
-  rewrite /uchiwa/(.*) /$1 break;
-}
-```
