Wish I could do pictures on here. Pm me and I can send one to an email or #.
You would be setting up the gate from the spindle to the opposite wall with the handrail. So first carpeted landing will be in the ungated area, which will be a nice place for the baby to practice steps.
I've found the pressure mounted, the simple cheap ones, very forgiving. My wooden spindle sticks out farther than the opposite wall and it still worked.
