 Here we provide a step-by-step guide showing how COEL can be deployed locally to Linux-based OS such as Ubuntu and partially to Mac OS (not tested). For Windows you can still use this guide but you need to adjust the os-specific parts such as settings of environmental variables. This guide applies to the most recent COEL release - 0.8.3.
 
-#### 1. Set up the environmental variables
+#### 1. Install Java 1.7
 
-* Download the file or copy paste the following:
+* Install OpenJDK or Oracle JDK version 1.7 manually or by using the package manager:
+```
+sudo apt-get install openjdk-7-jdk
+```
+or
+```
+sudo add-apt-repository ppa:webupd8team/java
+sudo apt-get update
+sudo apt-get install oracle-java7-installer
+```
+* Be sure that your `JAVA_HOME` points to the installation! For instance:
+```
+JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64
+```
+
+#### 2. Set up the environmental variables
+
+* Download the [file](http://peterbanda.net/coel/0.8.3/environmental_setting) or copy paste the following:
 ```
 export COEL_DBUSER=coeladmin
 export COEL_DBPASSWORD=CHANGE_ME

 * Override the variable values, especially those marked with `CHANGE_ME`.
 
 * Copy the settings to the central init script such as `/etc/environment` (recommended), `.bashrc`, or `.bash_profile`.
-  Note that to load these variables, a new login or restart might be required.
