## Description

This extension is dedicated to identify the presence of Kelkoo Leadtag and Google Tag Manager Container along with finding which Shop Solution the website is built on. 

This will give you a heads up on the working of Kelkoo Sales Tracking and also help you identify if GTM could be a better way to install KST for the website.

This extension can be used by both Kelkoo and the merchant to check these information.

With added features the extension now provides the user "Suggested Documentation" section which recommends them the correct documentation to install KST.
