+RVController Built-in Monitor
+=============================
+
+RVController contains a built-in machine-code monitor accessible by connecting a keyboard
+on channel "monitorkb" and a display on channel "monitordisp".
+
+For best results, use the keyboard and CRT ("cathodic") monitor from the digiterms mod:
+https://content.luanti.org/packages/mt-mods/digiterms/
+
+After connecting these devices and programming the Luacontroller, the following should be displayed:
+
++--------------------+
+|Reset: Cold         |
+|                    |
+|RVController Monitor|
+|                    |
+|Type 'help' for help|
+|Ready               |
++--------------------+
+
+Once you see this display, the monitor is ready to accept commands. The valid commands are:
+
+peek <address>
+Reads and displays the byte (8 bits) value from RAM at the specified address
+
+poke <address> <data>
+Writes the specified byte (8 bits) value to RAM at the specified address
+
+peekw <address>
+Reads and displays the word (32 bits) value from RAM starting at the specified address
+
+pokew <address> <data>
+Writes the specified word (32 bits) value to RAM starting at the specified address
+
+getreg <register number or name>
+Displays the current value of the specified register number (0-31)
+
+setreg <register number or name> <value>
+Sets the specified register (0-31) to the specified value
+
+getpc
+Displays the current value of the program counter
+
+setpc <value>
+Sets the program counter to the specified value
+
+reset
+Stops the CPU, resets all registers to zero, and clears all RAM
+
+step
+Allows the CPU to run for one instruction, then halts
+
+run
+Allows the CPU to run indefinitely
+
+stop
+Halts the CPU
+
+setbreak <address>
+Sets a breakpoint on the specified address.
+Note that the breakpoint triggers just *before* the instruction fetch,
+as in the instruction with the breakpoint on it will not have executed yet.
+There can only be one breakpoint at a time. If one is already set, the new one will replace it.
+
+clearbreak
+Clears any set breakpoint. Note that an ebreak instruction will still cause a break.
+
+help [command]
+Shows information on a monitor command, or a list of commands if none is specified.
+Use 'help 2' to see the second page
+
+rdcsr <CSR address or name>
+Displays the contents of the specified CSR
+
+wrcsr <CSR address or name> <data>
+Writes the specified data to the specified CSR, then reads back and displays the new value.
+Note that the new value may not match the written value if any read-only or WARL fields were written to.
+
+endian [big|little]
+With no arguments, displays the current endianness.
+With the argument "big" or "little", sets the current endianness to big-endian or little-endian respectively.
+This can also be viewed or changed using the MBE bit in the mstatush CSR.
