+
+Introduction to STM32
+=====================
+
+.. FIXME [v0.0.13] Stub page.
+
+Every Maple board is powered by an STM32 microcontroller (the chip
+which controls all of the pins).  Once you're comfortable using your
+Maple, you'll probably start to get curious about what's going on
+under the hood.  This page is a good place to begin.  It includes an
+overview of the STM32, and helps you make sense of the sometimes
+dizzying array of features, libraries, and documentation that are
+available to you.
+
+The world of the STM32 is a big one, and it's only getting bigger.
+With literally thousands of pages of manuals, datasheets, application
+notes, etc. available for every STM32 microcontroller, and a huge
+variety of categories and subcategories of STM32s available to choose
+from, it's easy to get confused or feel daunted about getting started.
+Don't panic!  We've got `your towel
+<http://en.wikipedia.org/wiki/Know_where_one%27s_towel_is#Knowing_where_one.27s_towel_is>`_
+right here.

+
+General Information
+-------------------
+
+- Description of the history and present state of the STM32 line. ARM
+  Cortex-M series etc.
+
+- Introduction and pointers to ARM Cortex-M docs and other good books
+  on the subject.
+
+- Pointers to ST reference manuals. Note that the appropriate
+  reference manual for each board is always documented in that board's
+  hardware page.
+
+.. _stm32-series:
+.. _stm32-series-f1-lines:
+
+STM32 Series
+------------
+
+- Describe families, F1 lines, etc.
+
+- Describe how a product name tells you what you need
+
+ST's Documentation
+------------------
+
+- Classes of documentation: product flyer, datasheet, reference
+  manual, programming manual, application note.
+
+.. _stm32-registers:
+
+Registers and Register Maps
+---------------------------
+
+- General purpose registers vs. peripheral registers.
+
+Perhaps you haven't read it in detail, but maybe you've at least
+thumbed through a few of the sections, trying to gain some
+understanding of what's going on.  If you've done that (and if you
+haven't, just take our word for it), then you know that underneath the
+covers, *everything* is controlled by messing with bits in the
+seemingly endless collections of registers specific to every
+peripheral.  The :ref:`USARTs <usart>` have data registers; (some of
+the) the :ref:`timers <timers>` have capture/compare registers, the
+:ref:`GPIOs <gpio>` have output data registers, etc.
+
+- Peripheral register maps; how they're duplicated for each peripheral
+
+- Portability concerns across series
+
+.. _stm32-libmaple-support:
+
+``libmaple`` STM32 support
+--------------------------
+
+- Descriptions of libmaple's present support for the STM32 line
+  (i.e. currently performance-line only; update when the F2 branch is
+  ready to merge into master etc.).
