+# Debugger commands
+
+These are the commands that the debugger CLI supports. Due to the asynchronous nature
+of the debugger and emulator, commands can be run even while the emulator is actively
+executing the program. For instance, try running the `disco.asm` <a href="/examples.html">
+example</a> and typing `set A #$0` into the debugger while it's running with a screen
+attached, you will be able to modify the program in real time!
+
+<br>
+Or, run the emulator on an empty file, and run `set $200 #$FF` to write to the frame
+buffer. You can even draw a picture by hand using just the debugger!
+
+<br>
+The GUI debugger actually just sends commands like these to the emulator using a
+message queue, and you can do the same. Look in `/dev/mqueue` for the message queue
+the emulator is using, and try sending a debug command as a null-terminated string
+to the queue, you should be able to interact with the emulator from a different
+process in real time.
+
+#### `step`, `s`
+
+Step through one CPU instruction
+
+#### `show [$addr]`, `print [$addr]`
+
+Show the value at `$addr` in memory, or, if no address given, show value of all registers.
+
+#### `set $addr #$val`, `set reg #$val`
+
+Set either `$addr` or register `reg` to `#$val`.
+
+#### `run`
+
+Run the emulator.
+
+#### `pause`
+
+Stop running the emulator.
+
+#### `quit`, `exit`
+
+Quit the debugger, emulator, and the screen (if running).
