+2. Fetch ``libmaple`` and Compiler Toolchain
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+First, make a Git clone of :ref:`libmaple`::

- $ cd libmaple
- $ wget http://static.leaflabs.com/pub/codesourcery/gcc-arm-none-eabi-latest-linux32.tar.gz

-In this step, you make a Git clone of the `libmaple repository
-<https://github.com/leaflabs/libmaple>`_, then download and extract

+Next, download the `Linux ARM GCC toolchain

+subdirectory somewhere in your ``PATH``. For example, if you have
+`wget <http://www.gnu.org/software/wget/>`_ installed, you can run::
-The directory :file:`arm/bin/` will need to be added to your ``PATH``;
-you can check that this worked by entering ``arm-none-`` and hitting

+(Optional) Upload/Debug with JTAG/SWD
+-------------------------------------
+
+Advanced users will wish to use a JTAG (or SWD) dongle for uploading
+and debugging their programs. A big advantage to this approach is that
+it lets you use `GDB
+<http://www.gnu.org/software/gdb/documentation/>`_ to single-step
+through your code, inspect variables, etc.
+
+You can build your projects for JTAG or SWD upload with the ``jtag``
+Makefile target. Instead of compiling with ``make``, compile with
+``make jtag``. Then use your method of choice to upload the resulting
+program, which will be in ``build/<your-board>.elf`` in the libmaple
+directory.
+
+.. warning:: Uploading code built with the ``jtag`` target will
+ overwrite the :ref:`bootloader <bootloader>`. This is a good thing
+ -- since you're using another upload method, this lets you use the
+ Flash and RAM the bootloader ordinarily reserves for itself. You
+ can always :ref:`reflash the bootloader <bootloader-reflashing>`
+ later.
+
+While LeafLabs doesn't officially support any particular way of using
+JTAG with Maple, there is a `JTAG How-To
+<http://wiki.leaflabs.com/index.php?title=Maple_JTAG_How_To>`_ on the
+`LeafLabs wiki <http://wiki.leaflabs.com>`_ that you may find useful.
