We need to use an allen wrench to align the bottom part of this mount to the insertion point on the camera.
Use the allen wrench to rotate it to allow it to slide inside your camera's insertion point
Place the mount on your camera, as it is shown in this image. Slowly; don't force it, slowly slide it in. You may need to readjust the black square to allow it to be inserted.
Then secure the mount by turning the round black wheel shown in this image
Make sure the mount is secure on top of the camera, make sure the black wheel is turned all the way to the right.
And You're Done
