 # StuyLib Network Keyboard
 
-WIP...
+### [NetKeyboard](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/keyboard/NetKeyboard.java)
+
+[NetKeyboard](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/keyboard/NetKeyboard.java) implements and simplifies interactions with keyboard information through a network table.

+
+[NetKeyListener](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/keyboard/NetKeyListener.java) listens for and uploads keyboard events to the keyboard network table.

+[NetKeyWindow](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/keyboard/NetKeyWindow.java) opens a Java AWT window and simulates a keyboard with a [NetKeyListener](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/keyboard/NetKeyListener.java) which can be used to control a robot.

-# StuyLib Gamepad Library
+# StuyLib Input Library
 
-WIP...
+The Input library contains classes which simplifies gamepad / keyboard input and standardizes the way input is handled and retrieved. 
+
+To learn about specific gamepads, [read here](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/gamepads/readme.md).

+To learn about keyboard input, [read here](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/keyboard/readme.md). 
+
+### [Gamepad](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/Gamepad.java)
+
+[Gamepad](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/Gamepad.java) is a class which standardizes the gamepad interface. It does not do anything by itself and must be extended by other gamepads. 
+
+### [GamepadState](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/GamepadState.java)
+
+[GamepadState](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/GamepadState.java) stores the state of a [`Gamepad`](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/Gamepad.java) separated by the different buttons and axis. Yet to be implemented, it can be used to "record" and "play back" gamepad input. 
+
+### [SPIGamepad](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/WPIGamepad.java)
+
+The [SPIGamepad](https://github.com/StuyPulse/StuyLib/blob/main/src/com/stuypulse/stuylib/input/WPIGamepad.java) class adds functions which make interactions with WPILib's `Joystick` class simpler.
