You mean the "ABOUT US" text or any thing in place of that.
If yes, then what is the problem go author the component dialog value.
Generally on any image component put a heading tag in html make it authorable and place it over image anywhere.
for reference you can refer your hero component
/apps/weretail/components/content/heroimage/heroimage.html
<div class="we-HeroImage-wrapper">
<p class="h3">${properties.heading}</p>
<strong class="we-HeroImage-title h1">${properties.title || currentPage.title}</strong>
