Hello,
Please consider following the Documentation > Start > Installation Section for this.
These are the following Folders/Files you will need for the Index Portfolio 3 Template:
css/ Folder
images/ Folder (However, you can delete the Images inside this Folder according to your Preference, but don’t delete the images/icons/ Folder)
include/ Folder (However, you can delete the rs-plugin/ Folder)
js/ Folder
style.css File
index-portfolio-3.html File
You can simply delete the other files depending on what you want to use.
This will definitely work fine. Hope this Helps!
