Front Page Help!!

Hello! I love this theme, but am having a few issues setting up the front page similar to the demo. I installed Sela after using a different theme, have jetpack and access to the Custom CSS Manager, and have set my front page to the “static” “front page” options.

My website is crmpi.org

Here are my issues:

-There is no option for me to add a logo above the navigation bar. Under “Site Title and Tagline” there is no button for me to upload a logo.

-I am unsure how to add a “hero image”… I assume this is the image with the white text box on top. I love this feature and wish to include it!

-Originally I tried adding a feature image to the page, however, the content box has totally superseded the image and sits right under the main nav.

I really appreciate your help!
