   <title>Installation</title>
   <para>The installation chapter provides information on how to install DHIS 2 in various contexts, including online central server, offline local network, standalone application and self-contained package called DHIS 2 Live.</para>
   <para>DHIS 2 runs on all platforms for which there exists a Java Runtime Environment version 6 or higher, which includes most popular operating systems such as Windows, Linux and Mac. DHIS 2 also runs on many relational database systems such as PostgreSQL, MySQL, H2 and Derby. DHIS 2 is packaged as a standard Java Web Archive (WAR-file) and thus runs on any Servlet containers such as Tomcat and Jetty.</para>
-  <para>The DHIS 2 team recommends Ubuntu 10.10 operating system, PostgreSQL database system and Tomcat Servlet container as the preferred environment for server installations. The mentioned frameworks can be regarded as market leaders within their domain and is heavily field tested over many years.</para>

   <para>This chapter provides a guide for setting up the above technology stack. It should however be read as a guide for getting up and running and not as an exhaustive documentation for the mentioned environment. We refer to the offical Ubuntu, PostgreSQL and Tomcat documentation for in-depth reading.</para>

     <title>Server setup</title>
-    <para>This section describes how to set up a server instance of  DHIS 2 on Ubuntu 10.10 64 bit with PostgreSQL as database system and Tomcat as Servlet container. The term <emphasis role="italic">invoke</emphasis> refers to executing a given command in a terminal. You can find the terminal in <emphasis role="italic">Applications</emphasis> - <emphasis role="italic">Accessories</emphasis> - <emphasis role="italic">Terminal</emphasis>.</para>
-    <para>For a national server the recommended configuration is a multicore 2 Ghz processor or higher and 12 Gb RAM or higher. Note that a 64 bit operating system is required for utilizing more than 4 Gb of RAM, the Ubuntu 10.10 64 bit edition is thus recommended. For this guide we assume that 4 Gb RAM is allocated for PostgreSQL and 7 GB RAM is allocated for Tomcat. If you are running a different configuration <emphasis role="italic">please adjust the suggested values accordingly</emphasis>. The steps related to performance tuning are not compulsory and can be done at a later stage.</para>

+    <para>You might want to create a dedicated user for running DHIS - it is not recommended to run as the root user. Create a new user called dhis  by invoking <code>useradd -d /home/dhis -m dhis -s /bin/bash</code>     Then make the user able to perform operations temporarily as root user by invoking <code>adduser dhis admin</code></para>
