Replace a shed door

[Fanatical Meat]

I need to replace my warped shed door it is a double door about 60” wide (give or take) and around 7 feet high, it is a double door.
Appears all out door rated ply wood is warped in my area is T1-11 (I think) siding an appropriate material to use?
Any decent and simple links that describe what I need to do?
Thanks guys

Need pictures.

T-111 may need to be painted or otherwise treated for weather.
