Need help with camera to fit to Screen

I have recently swapped from Apple Sprite-Kit to Unity (Complete beginner here) and have encountered a camera problem.

The problem is that I am unable to fit my camera to the map that I have created in Tiled + Tiled2Unity. In the previous engine I used, I scaled the scene to fit the camera or vice versa, so for Unity how do I do that?

Either adjust the orthographic size of the camera, or scale up your scene’s contents.

You can scale the size of the camera right on the Inspector under camera:
