+Change the Default Configuration and Data Directory
+===================================================
+
+|CL| is designed to be a stateless operating system which means that you will
+need to create an optional configuration file.  The default location of the
+Apache configuration file, httpd.conf, is located in the
+/etc/share/defaults/httpd directory, which can be overwritten as part of the
+stateless paradigm.  This default .conf file includes the following directives
+that allow for additional locations of configuration definitions:
+
+.. code-block:: console
+
+   # Virtual hosts
+   IncludeOptional /usr/share/defaults/httpd/conf.d/*.conf
+   IncludeOptional /usr/share/defaults/httpd/conf.modules.d/*.conf
+   IncludeOptional /etc/httpd/conf.d/*.conf
+   IncludeOptional /etc/httpd/conf.modules.d/*.conf
+
+
+For this tutorial, we will create the directory structure for /etc/httpd/conf.d
+and then create the httpd.conf file within /etc/httpd/conf.d directory and
+include the variable DocumentRoot.
+
+Using your favorite editor, copy the content listed below into the new file
+:file:`/etc/httpd/conf.d/httpd.conf`
+
+.. code-block:: console
+
+   #
+   # Set a new location for DocumentRoot
+   #
+   DocumentRoot “/var/www/html”
+   
+   #
+   # Releax access to content within /var/www/html for this tutorial
+   #
+   <Directory “/var/www/html”>
+      AllowOverride none
+      Require all granted
+   </Directory>
+
+
+Finally, let’s create the new DocumentRoot directory structure and copy the
+index.html file from /usr/share/httpd/htdocs directory to /var/www/html.
+
+.. code-block:: console
+
+   sudo mkdir –p /var/www/html
+   cd /var/www/html
+   sudo cp /usr/share/httpd/htdocs/index.html .
+
+
+To make sure that we have everything set correctly, let’s edit the new
+index.html file with your favorite editor and change the text from
+“It works” to “It works in it’s new location”.
+
+With the new configuration files in place, you will need to stop and then restart the httpd.service
+
+.. code-block:: console
+
+   sudo systemctl stop httpd.service
+   sudo systemctl start httpd.service
+
+
+Now when you go to http://localhost you should see your new screen.
