Attatching plasterboard to underside of staircase

[ghoulder]

Hi
I am in the process of converting a dry cellar into a more usable space. I will be attaching plasterboard to the underside of the staircase to the 1st floor in the house but am having difficulty picturing how I attach this to the staircase in terms of any studwork needed. Any advice would be helpful on attaching the studwork frame to create a level base to screw the plasterboard to.

Hope that makes sense.

Thanks

there is always a way but it is hard to know what to suggest without seeing it. Maybe if you post a photo?
