Apache change DocumentRoot

Every time i forget what has to be done to stop with the "Forbidden" page after i change the Root directory. So first add the user you use to add/update/delete your files to www-data group.

usermod -a -G www-data mraiur

Update permissions of file that must be writable by www-data and the user

chmod 0775 FILE

Then in the 000-default in /etc/apache2/sites-available put :

DocumentRoot /NEW_PATH
<Directory "/NEW_PATH">
    Options Indexes FollowSymLinks
    AllowOverride None
    Require all granted
    Order allow,deny
    Allow from all
