+Multicore Processing
+====================
+
+The RP2040 chip has 2 cores that can run independently of each other, sharing
+peripherals and memory with each other.  Arduino code will normally execute
+only on core 0, with the 2nd core sitting idle in a low power state.
+
+By adding a ``setup1()`` and ``loop1()`` function to your sketch you can make
+use of the second core.  Anything called from within the ``setup1()`` or
+``loop1()`` routines will execute on the second core.
+
+``setup()`` and ``setup1()`` will be called at the same time, and the ``loop()``
+or ``loop1()`` will be started as soon as the core's ``setup()`` completes (i.e.
+not necessarily simultaneously!).
+
+See the ``Multicore.ino`` example in the ``rp2040`` example directory for a
+quick introduction.
+
+Pausing Cores
+-------------
+
+Sometimes an application needs to pause the other core on chip (i.e. it is
+writing to flash or needs to stop processing while some other event occurs).
+
+void rp2040.idleOtherCore()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Sends a message to stop the other core (i.e. when called from core 0 it
+pauses core 1, and vice versa).  Waits for the other core to acknowledge
+before returning.
+
+The other core will have its interrupts disabled and be busy-waiting in
+an RAM-based routine, so flash and other peripherals can be accesses.
+
+**NOTE** If you idle core 0 too long, then the USB port can become frozen.
+This is because core 0 manages the USB and needs to service IRQs in a
+timely manner (which it can't do when idled).
+
+void rp2040.resumeOtherCore()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Resumes processing in the other core, where it left off.
+
+Communicating Between Cores
+---------------------------
+
+The RP2040 provides a hardware FIFO for communicating between cores, but it
+is used exclusively for the idle/resume calls described above.  Instead, please
+use the following functions to access a softwarae-managed, multicore safe
+FIFO.
+
+void rp2040.fifo.push(uint32_t)
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Pushes a value to the other core.  Will block if the FIFO is full.
+
+bool rp2040.fifo.push_nb(uint32_t)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Pushes a value to the other core.  If the FIFO is full, returns ``false``
+immediately and doesn't block.  If the push is successful, returns ``true``.
+
+uint32_t rp2040.fifo.pop()
+~~~~~~~~~~~~~~~~~~~~~
+
+Reads a value from this core's FIFO.  Blocks until one is available.
+
+bool rp2040.fifo.pop_nb(uint32_t *dest)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Reads a value from this core's FIFO and places it in dest.  Will return
+``true`` if successful, or ``false`` if the pop would block.
+
+int rp2040.fifo.available()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Returns the number of values available in this core's FIFO.
