+### Node & NPM
+
+You first need to install **node** and **npm**.
+
+At the time of writting this documentation, latest Etherpad Lite (1.2.11) wasn't working with latest stable node.js version (v0.10.16).
+
+You can download precompiled *node.js v0.8.25* from http://nodejs.org
+
+<pre>
+$ wget http://nodejs.org/dist/v0.8.25/node-v0.8.25-linux-x64.tar.gz
+$ tar -vxzf node-v0.8.25-linux-x64.tar.gz
+$ rm node-v0.8.25-linux-x64.tar.gz
+$ mv node-v0.8.25-linux-x64 /opt
+$ ln -s /opt/node-v0.8.25-linux-x64/bin/node /usr/local/bin/node
+$ ln -s /opt/node-v0.8.25-linux-x64/bin/npm /usr/local/bin/npm
+</pre>
+
+You can check node's version:
+
+<pre>
+$ node --version
+v0.8.25
+</pre>
+
+### Etherpad Lite
+
+You can get the latest version from github, configure and deploy as a service.
+
+<pre>
+# Install etherpad-lite
+$ git clone git://github.com/ether/etherpad-lite.git /usr/share/etherpad-lite
+$ sh /usr/share/etherpad-lite/bin/installDeps.sh
+
+# Configure Etherpad settings
+$ nano /usr/share/etherpad-lite/settings.json
+
+Usually you set a mysql database for etherpad here.
+
+# Create a user called etherpad-lite
+$ useradd -r -d /bin/false etherpad-lite
+
+# Create a log folder for the service /var/log/etherpad-lite
+$ mkdir /var/log/etherpad-lite
+
+# Ensure the etherpad-lite user have full access to the log and the git folder
+$ chown -R etherpad-lite /var/log/etherpad-lite
+
+# Copy following script to /etc/init.d/ and configure the variables
+$ cp ep-daemon /etc/init.d/etherpad-lite
+
+# Make sure the script is marked as executable
+$ chmod +x /etc/init.d/etherpad-lite
+
+# Enable it with
+$ update-rc.d etherpad-lite defaults
+</pre>
+
+Provided **ep-daemon** if for Debian and Ubuntu, you can get more daemons in the [Etherpad Lite Wiki](https://github.com/ether/etherpad-lite/wiki/How-to-deploy-Etherpad-Lite-as-a-service).
+
+You can run Etherpad Lite with:
+
+<pre>
+service etherpad-lite start
+</pre>
+
+Etherpad Lite should be running on http://localhost:9001/
+
+### Reverse Proxy
+
+You can read [How to put Etherpad Lite behind a reverse Proxy](https://github.com/ether/etherpad-lite/wiki/How-to-put-Etherpad-Lite-behind-a-reverse-Proxy) from Etherpad Wiki to know how to serve resources from 9001 port to / path.
+
+To integrate Etherpad with Elgg, we need it served in a /pad subpath, becuase whey are sharing cookies.
+
+This is an example for apache2:
+
+<pre>
+  Redirect /pad /pad/
+
+  LoadModule  proxy_module         /usr/lib/apache2/modules/mod_proxy.so  
+  LoadModule  proxy_http_module    /usr/lib/apache2/modules/mod_proxy_http.so
+  LoadModule  headers_module       /usr/lib/apache2/modules/mod_headers.so
+  LoadModule  deflate_module       /usr/lib/apache2/modules/mod_deflate.so
+
+  ProxyVia On
+  ProxyRequests Off
+  ProxyPass /pad/ http://localhost:9001/
+  ProxyPassReverse /pad/ http://localhost:9001/
+  ProxyPreserveHost on
+  <Proxy *>
+      Options FollowSymLinks MultiViews
+      AllowOverride All
+      Order allow,deny
+      allow from all
+  </Proxy>
+</pre>
+
+### Elgg Plugin
+
+Once you have Etherpad Lite running, it's the turn to Elgg. Go to the admin area and activate the plugin. Then, in it's configuration write the API KEY you can find in API-KEY.txt.
+
+<pre>
+$ cat /usr/share/etherpad-lite/APIKEY.txt
+</pre>
+
+Enjoy your new installation!
