Hello. i have been reading reviews on twitter product card, and also tried to make it work on my site, unsuccessfully so far, because keep getting invalid card type error. Based on this reviews i believe there is a step or two missing in your installation instructions and here are my questions. 1. do i need to specifically allow twitterbot on my robots.txt ? 2. do i need to add an additional twitter button under product,(if i have addthis installed) 3. do i need to copy the generated by https://dev.twitter.com/docs/cards/validation/validator code into my store meta? 4. am i validating a one certain product url from my site, or the url to my store? thanks!

I am trying to use this mod but the installation instructions are very vague. How do one set it up in zen cart admin and does it automatically update the products when I add new ones or do I have to change the page manually?
