Portfolio – How Do I Change "Skills Used" to "Features"

I would like to change the displayed terminology on the Portfolio page. How do I change the term “Skills Used” to “Features.” I am using the portfolio feature to display products and would like to use the portfolio filters items to define product features.

Ie. Currently displayed:

Skills Used:

finished interior
green roof

Preferred display:

Features:
