 Description
 -----------
 **JuJu** is a small and portable GNU/Linux distribution based on ArchLinux.
+It allows to have an isolated GNU/Linux environment inside the home directory
+without the need to have root privileges that is accessible via chroot and run
+on whatever Linux distribution.
 
-JuJu can be used inside another GNU/Linx OS via chroot.
-It only contains the package manager (called pacman and yaourt) in order to access
+JuJu only contains the package manager (called pacman and yaourt) in order to access
 to a wide range of packages from ArchLinux repositories.
 
-The main advantage of using JuJu is because you have an isolated environment
-in which you can install packages without affecting a production system.
-Another advantage is that with JuJu you can access to a really wide range
-of packages inside GNU/Linux systems that contains limited repositories
-(such as CentOS and RedHat).
+The main advantage of using JuJu are:
+- It gives an isolated environment in which you can install packages without affecting a production system.
+- Access to a really wide range of packages even inside GNU/Linux systems that contains limited repositories (such as CentOS and RedHat).
+- Install packages without the need to be root.
 
 Quickstart
 ----------
-After installing JuJu (see next section) just run the main juju script:
-```bash
-juju
-```
+After installing JuJu (see next section) you can run juju either as root or as normal user.
+To run as root:
+
+    # juju
+
+To run as normal user:
+
+    $ juju -n
+
 The first time you execute it, the script will download the JuJu image and place it
 to the default directory ~/.juju.
-You will need root privileges in order to acces to the chroot.
 
 Installation
 ------------
 Just clone JuJu somewhere (for example in ~/juju):
 
-```bash
-git clone git://github.com/fsquillace/juju ~/juju
-export PATH=~/juju/bin:$PATH
-```
+    $ git clone git://github.com/fsquillace/juju ~/juju
+    $ export PATH=~/juju/bin:$PATH
 
 JuJu can only works on GNU/Linux OS with kernel version greater or equal
-2.6.32 in 32 or 64 bit.
+2.6.32 on 64 bit architecture (32 bit and arm will be available soon).
+
+Advanced usage
+--------------
+You can build a new JuJu image from scratch by running the following command:
+
+    # juju -b
+
+In this way the script will create a directory containing all the essentials
+files to make JuJu working properly (such as pacman, yaourt, arch-chroot and proot).
+Remember that the script to build the image must run in an ArchLinux OS with
+arch-install-scripts installed.
+
+To install the image named juju-x86\_64.tar.gz:
+
+    # juju -i juju-x86_64.tar.gz
