I'm creating a plugin/extension that changes/replaces the default review tab content inside of catalog/product/view.phtml.
What are the steps involved in injecting such code to Magento frontend? I already have the plugin as described by this tutorials.
Of course I can go to the template directory and manually modify the HTML there but I need the edits to be made by the plugin on whatever theme is currently installed/used.
Couldn't find any tutorials or documentation about that
