Filterific: Collection Filter

where do i get the documentation? or steps to follow to add filters to collection pages. thanks in advance

Although the monthly fee is very fair, they ask for $25.00 to install the app. So I tried installing it myself but gave up after seeing how much work it would take and some of the instructions wern't specific enough.
This app would be great if it had better installation directions.
Right now I won't use it if I can find one that is easier to install.

Looks Great! Wish it was more user friendly... An interface that you can use within the collection page builder would be much better than having to write code or pay $25 for them to do the coding for you. Love the concept.. But dont like the usability

Uninstalled after 3 minutes. Too bad user interface - did not understand how it worked but it screwed up our filters, so we have to pay a developer for fixing it :(
I cannot recommend this app.
