 # CTroll3D
-Use 3DS as Citra gamepad
+
+CTroll3D is a 3ds homebrew that allows you to control the Citra emulator on from your 3ds.
+For this to work, you need a version of Citra that supports CTroll3D (for now, only my own fork of Citra) and the CTroll3D homebrew on your 3ds.
+
+CTroll3D supports:
+
+- DPAD
+- CPAD
+- Touch
+- Accelerometer
+- Gyroscope
+- Bottom screen mirroring
+
+One advice: glReadPixels and VSync doesn't doesn't perform too well. So, to increase  the performance, please disable the VSync (and some other heavy stuffs like Accurate Multiplications). You can access these options in Preferences -> Graphics -> Advanced.
+
+In some cases, the bottom screen mirroring can slow down your emulation, and should be disabled by pressing L + R + DOWN + click on Touch (and can be enabled by L + R + UP + click on Touch).
+
+How to Use:
+
+1 - Open the CTroll3D homebrew on your 3ds
+2 - On Citra, access the menu option: Tools -> Connect CTroll3D and enter your 3DS IP Address
