How to edit "Project Overview" label

Hello

I recently purchased Bostan theme and now developing it.

For Projects / portfolio section, Please let me know How to edit:
– “Project Overview” to “Product Overview”
– “Project Details” to “Product Details”
– “Other Projects” to “Other Products”

mainly speaking, I want to utilize this module to make my product showcase, instead of project.
