How can I override taxonomy term page? I have created a Vocabulary (categories) with terms (term1, term2, term3..etc). After that I created a content type (Product) with fields title, description, image. Also, created field called "product type" which is a term reference (categories). Furthermore, I am displaying  all terms list in page like term1 term2 term3 with link. 

When I click on term1 I want to display related products name, description, image with full details link. I am currently displaying only term related product title with read more link only.

Please Advice.
You could install Views module, create a list of products, and filter based on taxonomy (Contextual filter).
