-Installing and updating OpenGnsys
+Installing OpenGnsys Server 1.1.0
 =================================
 
+Before installation
+-------------------
 
+OpenGnsys Server 1.1.0 is meant to be installed under Ubuntu Server 16.04 LTS or newer, though it has also been tested under operating systems based on CentOS 7.
 
-Installing OpenGnsys
---------------------
+Network connection is needed in order to download the required packages, the source code and the preconfigured client.
+
+Minimum storage requirements:
+- 100 MB in /tmp (for the installation process)
+- 600 MB in /var/lib/tftpboot (or /srv in Debian systems) for every installed ogLive client.
+- 250 MB in the installation folder (/opt/opengnsys) plus 600 MB for every downloaded ISO image.
+- Enough disk space for the image repository in /opt/opengnsys/images (it is recommended to mount it on an independent file system)
+
+
+
+Installing
+----------
 
+To install OpenGnsys, run opengnsys_installer.sh script after unpacking the release file (opengnsys-release.tar.gz) or after downloading it directly from https://raw.githubusercontent.com/opengnsys/OpenGnsys/master/installer/opengnsys_installer.sh
 
-Run opengnsys_installer.sh script as "root" to install all its dependencies, to install the OpenGnsys components, and to make the initial configuration.
+Unpacking example:
+	tar xvzf opengnsys-Version.tar.gz
+	cd opengnsys/installer
 
-           sudo bash opengnsys_installer.sh
+Downloading examples:
 
-Follow the instructions.
+    * Download with wget.
