advanced custom fields – ACF – Compare Products Feature


I have created Product pages with their respective specifications using ACF.

Now, i would like to add a product comparison feature with 2 or 3 products.

Upon research, i found that a Compare input field is needed beside every product in the Products Page and this information has to be passed on to the Comparison page.

There are many steps to achieve the final working model.

Can anyone guide me with the steps along with codes to get started?
