Place the sundial so that the slot corresponds to your latitude.
If you are at the 45th latitude set the coin/sundial slot to be at 45 degrees from horizontal.
Put the sundial base (or make a base out of pine-tar or gum) on a level surface.
So the sundial face is vertical with the slot at the correct angle.

Count where you see the light from the edge of the dial in 1/12ths, each 1/12th equaling a hour.
Starts at 6 am and the other side of the dial is 6 pm, the middle is noon.

These people sell a real nice brass version. This also is where I got the ideas to make this one. Thank you.

Here is a video of this type of sundial.

I don't use month of year adjustments, just angle it so the light line is as thin as possible and centered in the shadow.

Count the bumps, they are worth 5 degrees of latitude each and place it in the stand.

Here is one I made from and an egg and some cardstock and some glue.
