Roll up garage door opener - standard style hack/DIY

Using a standard overhead style garage door opener for my metal roll up garage doors.
1: genie 1.25hp belt opener installed on my 9’ high x 10’ wide roll up doors. NO extension kit needed. If your doors are higher than 9’ then yes you’ll need to use their extension kit.
Using this for 6 months with zero issues. The only issue I had originally was that the doors were tensioned too heavily from the installers. I had to look online and found a PDF instruction that showed how to release excessive tension. Once I neutralized the doors, everything functioned great.
DONT OVER THINK this guys. I’ve seen some videos of guys over engineering this and investing more time and money than is needed.
Good luck!
