Help configuring a web map

i found web map template created by esri to address Section 508 and WCAG2.0 concerns

however i am having trouble getting to work, mostly because i dont have the programming background to figure it out on my own, i originally posted on geonet asking for help but got nothing so i am turning to reddit to see if any one can help me.

right now i really just want to use my data with the map and figure out how to configure the legend.

as an FYI i can follow directions but treat this as an ELI5
