+
+### STEP-BY-STEP INSTALLATION
+
+Whether you're on Ubuntu or Debian you can quickly install EGroupware by following below steps:
+
+#### step 1:
+Add EGroupware repository into source lists in order to fetch EGroupware's packages.
+
+```
+ vi /etc/apt/source.list.d/egroupware-epl.sources.list
+```
+
+There's two different repository; one is for EPL version and other one is for Community version, please add relevant repository based on the version you would like to install.
+EPL Repository:
+```
+#EGroupware EPL repository
+deb http://USERNAME:PASSWORD@download.egroupware.org/repos/stylite-epl/DISTRO_NAME/ ./
+```
+Example:
+```
+#EGroupware EPL repository
+deb http://peter:secret@download.egroupware.org/repos/stylite-epl/xUbuntu_16.04/ ./
+```
+Community Repository:
+```
+#EGroupware Community repository
+deb http://download.egroupware.org/repos/stylite-epl/DISTRO_NAME/ ./
+```
+Example:
+```
+#EGroupware Community repository
+deb http://download.egroupware.org/repos/stylite-epl/xUbuntu_16.04/ ./
+```
+Replace the following variables used in above urls with your own values:
+*USERNAME*:*PASSWORD* are your given credentials for EPL version.
+
+*DISTRO_VERSION*: Means the version of distribution you're install EGroupware on it. You can find out the right version name from following list:
+
+
+*** if you are not sure what distribution you're running, simply execute the following command:
+```
+cat /etc/os-release
+```
+
+#### Step 2:
+After adding EGroupware's repository into sources list, we need to update to fetch packages. Before doing the update we are going to make sure that we have the repository key
+added.
+
+EGroupware EPL Version:
+```
+wget -O - http://USER:PASSWORD@download.egroupware.org/build%40egroupware.org | apt-key add -
+```
+OR
+
+EGroupware Community Version:
+```
+wget -nv https://download.opensuse.org/repositories/server:eGroupWare/xUbuntu_16.04/Release.key -O Release.key | apt-key add -
+```
+
+```
+apt update
+```
+
+#### Step 3:
+
+Now it's time to install egroupware-epl packages. Depends on the webserver you
+would like to use with EGroupware, you may install a webserver among the egroupware-epl
+packages, by default Apache will be installed.
+
+``` apt install egroupware-epl ```
+
+e.g. for nginx installation:
+
+``` apt install nginx egroupware-epl```
+
+follow the installation instruction as shown in following figures:
+
+``In the following instructions whenever you leave a password fields empty,
+a randomized password gets generated which you can get access to it via egroupware-epl.log
+file after installation is completed.``

+![alt text]("https://www.github.org/EGroupware/wiki/figure6.png")
+
+#### Step 4:
+You may check egroupware-epl.log file in order to check if everything went well during the installation plus you can get access to your egroupware credentials.
+
+```
+less /root/egroupware-epl.log
+```
+
+from this moment on you may get logged in to your EGroupware instance via the mentioned
+url in egroupware-epl.log. Although, before doing that we highly do recommend to take couple of more steps to adjust couple of settings for [PHP and MyQL](https://www.github.org/EGroupware/wiki/configure_php_and_mysql) in order to get the best performance.
+
+#### Step 5:
+Congratulations!!!
