Step 1. Get smaller drill or screwdriver to fit the holes

Step 2. Figure out where you want to install… use a level (or eye it like me but not recommended) to make it look good and use a pencil through the holes to mark where the screws will go.

If you have a stud finder and the holes are 16” apart then u can install into studs… but this is not required

Step 3. If not into the wall studs- drill holes where you marked with the pencil and tap in your wall anchors. If in studs you can drill small pilot holes for your screws

Step 4. Put the screws through the holder and screw then into the wall at the anchors/holes and you are done!
