Convert simple PC game to Android?

Hello! This is my first post here so it might be in the wrong place. Im sorry.

But the actual question I wanted to ask was, that I have made a simple first person game on pc, that currently has 3 buttons, mouse to look, wasd or arrows to move and f to toggle flashlight. I used the first person controller thingy that you have to import. But now I want to make the game run on android. So what do I do? I have Android SDK installed and Unity knows where it is. I just wanna add touchscreen controls to the game rather easily… Just like a joystick to move, swipe anywhere else to move camera and button for flashlight, maybe…
But mostly, what do I do to my PC project to make it an Android project and add android controls to it?
Thanks for any help and sorry for my english.

The awnser is “Yes” you could simply get a first person controls and add all your scripts on.
