Install the plug-in using the following step-by-step process:
Download the zip package of Tapatalk Plugin for xenForo to your computer.
Unzip the package. You should see two folders ('mobiquo' and 'library') and two files ('addon-tapatalk.xml' and 'license_agreement.txt').

Upload the entire 'Tapatalk' folder from 'library' folder to your forum system 'library' directory. For example, if your forum URL is http://www.mysite.com/forum, your Tapatalk folder should be at the address http://www.mysite.com/forum/library/Tapatalk.
Login to AdminCP, go to 'Home' -> 'Add-ons' -> 'Install Add-on'.
Click 'Choose File' button.
Choose 'addon-tapatalk.xml' file which is unzipped from Tapatalk Plugin package in your computer. Click 'Open'.
You will see 'Tapatalk' listed in the 'Installed Hooks' section.
