The first step is to sign up for the mobile website service in the plus tab of your freetoook account
Once you have done this you have to add a script tag to the head section of each page on your site
The script tag will look like this example below. This is just a sample, you can get the correct code from the mobile website page under the plus tab.
Once you have inserted the code your page source will look something like this.
When the code has been correctly added it will detect when a mobile device is being used and redirect to the mobile site.
