How to work with the datalayer in Shopify?

[ianantwalks]

Hello Everyone.

First of all, I don't have a Shopify Plus subscription.

How can I implement a data layer on my Shopify store so that I can push product data to the Google Tag Manager data layer to then be able to use that data in something like, say, Google Analytics?

Is there a free way to do this?  I'm not really a developer, but I might be able to figure it out if someone is kind enough to help.

Our store already has the Google Tag Manager tag implemented, I just need help creating the code to capture product data to pass to the data layer.

Many thanks.
