+# Controller Slide Presenter
+
+A small tool to emulate a Slide Presenter using a Wiimote or a Joy-Con.
+
+## Controls
+
+### Wiimote
+
+- A or Right - Next Slide
+- B or Left - Previous Slide
+
+### Joy-Con
+
+- A or ZL/ZR - Next Slide
+- B or L/R - Previous Slide
+
+## Platform Support
+
+### Windows
+
+For the Joy-Con you just need to connect it via Bluetooth and then run the program.
+
+For the Wiimote you may need to connect it using Dolphin Emulator and then just run the program.
+
+**WARNING:** It's possible that Steam tries reading the Joy-Con in the background and keeps it from working.
+
+### Linux
+
+**Prerequisite:** You need [xdotool](https://github.com/jordansissel/xdotool) installed in order to redirect the input.
+
+At the moment there's only Joy-Con support, so connect it via Bluetooth and run the program.
+
+### MacOS
+
+At the moment there's no MacOS support as I don't have a computer to test, but feel free to submit a Pull Request adding that feature, the Joy-Con reading should work just fine, only the input redirection is needed.
+
+## Packages used
+
+**JoyCon.NET** - ([GitHub](https://github.com/ClusterM/joycon)) ([NuGet](https://www.nuget.org/packages/JoyCon.NET))
+
+**WiimoteLib.NetCore** - ([GitHub](https://github.com/BrianPeek/WiimoteLib)) ([NuGet](https://www.nuget.org/packages/WiimoteLib.NetCore))
