 Setup instructions
 
 * make sure bower, composer and npm are available on command line
-** e.g. for Ubuntu 16.04 (VIRL 1.3.156 host):
-*** "sudo apt-get install npm"
-*** "sudo apt-get install nodejs-legacy"
-*** "sudo npm install -g bower"
-*** "sudo apt install libapache2-mod-php7.0 php7.0-sqlite3 php-xml php-curl"
-*** "curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer"

+    * "curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer"
 
 * run **npm update** in virl-scheduler root directory (only if you want to test in devmodes, apache is enough otherwise)
 * run **bower update** in virl-scheduler root directory, afterwards verify **bower_components** directory was created
 * run **composer update** in virl-scheduler root directory, afterwards verify **vendor** directory was created
 
 * configure apache to use **virl-scheduler** and **index.html** as webroot (make sure rewrite engine is on and .htaccess files are parsed by apache)
-** e.g. for Ubuntu 16.04 (VIRL 1.3.156 host):
-*** copy virl-scheduler to your webroot: "sudo cp -a virl-scheduler /var/www/html/"
-*** add "ProxyPass /virl-scheduler !" to the ProxyPass directives in **/etc/apache2/sites-available/000-default.conf**
-*** allow .htaccess in virl-scheduler api directory, e.g., by appending the following lines to **/etc/apache2/sites-available/000-default.conf**

         <Directory /var/www/html/virl-scheduler/api>
                 AllowOverride All
         </Directory>
-*** give the Apache2 process write permissions to the sqlite3 db by running "sudo chown www-data:www-data api/db.sqlite3" and "sudo chown www-data:www-data api" in the virl-scheduler directory
-*** run **service apache2 restart**
+        ```

+* run **service apache2 restart**
 
 * Change hostname for **VIRLRestangular factory** in **app/topologyManager.js** and **api/cron.php** to your VIRL-API-Hostname or IP-Address.
 
 * Add a cron job to run the scheduler, e.g., every five minutes and start planned simulations
-** e.g. for Ubuntu 16.04 (VIRL 1.3.156 host):
-*** "sudo crontab -e" add "*/5 * * * * /usr/bin/curl -o /var/log/virl-scheduler-cron.log http://localhost/virl-scheduler/api/cron.php" at the end of the file
+  * e.g. for Ubuntu 16.04 (VIRL 1.3.156 host):
+    * "sudo crontab -e" add "*/5 * * * * /usr/bin/curl -o /var/log/virl-scheduler-cron.log http://localhost/virl-scheduler/api/cron.php" at the end of the file
 * Have fun using the scheduler to start VIRL simulations automatically, by accessing /virl-scheduler on your VIRL host. Login using a VIRL username and password, be sure to add a Session name (simulation name) and a VIRL topology (XML source of a topology file)
 
 * output of the cron job can be seen in **/var/log/virl-scheduler-cron.log** or by accessing http://<VIRL-Host>/virl-scheduler/api/cron.php" manually in your browser
