What are some of the pre-requisites to using this App?
This App helps you create and maintain an online FAQ support system. In order to publish the FAQ system online, you will need an FTP account to your website. You most likely already have your own business or service website, you will be able to easily integrate this component into your web page by adding a web link to the FAQ tool from the main website.
For those technically inclined folks, this App will require the web host provider to support PHP.
On the other hand, if you are not sure what PHP is, it's a web script that is supported by just about all web host providers. It doesn't hurt to ask your web host provider to ensure it's supported and turned on for your website.
