Unix Toolchain Quickstart
===========================

-(``make``, ``gcc``, etc.). It's not necessary to do this in order to

-We currently have instructions for 32- and 64-bit Linux and OS X Snow
-Leopard. If you're on another Unix platform, Windows, or an earlier
-version of OS X, we imagine you can translate/port these directions on
-your own. You might want to begin with these `stripped down

-`CodeSourcery GCC compiler tools

-On Debian-based distributions (including Ubuntu, etc.), do this with::
+On Debian-based distributions (including Ubuntu)::

-``wget`` is a simple tool to download files over http from the command

-connect to serial port devices.
+* `Git <http://git-scm.com/>`_ is a distributed version control
+ system. We use it to track our source code.

+ Python. (Most Linux distributions these days include Python by
+ default).
-``openocd`` is a `JTAG

+
+2. `Install Python <http://python.org/download>`_. Choose the latest
+**2.7.x version**; Python 3 will not work.
+
+3. `Install PySerial <http://pypi.python.org/pypi/pyserial>`_. Choose
+the latest **pyserial-x.y-win32.exe version**; the "py3k" version will
+not work.
+
+4. Run Git Bash, and get :ref:`libmaple` by typing the following line
+and hitting return. (Do not type the "$". We put these in to remind
+you that lines like this are for the Git Bash prompt). ::
+
+ $ git clone git://github.com/leaflabs/libmaple.git
+
+.. note:: Keep the Git Bash window open as you go.
+
+You now have the libmaple repository in the folder ``Documents and
+Settings\<Your Name>``.
+
+5. Download this `archive of the CodeSourcery compiler toolchain
+<http://static.leaflabs.com/pub/codesourcery/gcc-arm-none-eabi-latest-win32.tar.gz>`_.
+When the download finishes, move the file into the libmaple directory.
+
+6. Type these two lines into the Git Bash prompt to go to the libmaple
+folder and extract the archive::
+
+ $ cd libmaple
+ $ tar xzf gcc-arm-none-eabi-latest-win32.tar.gz
+
+This will create a folder named "arm" inside the libmaple folder.
+

+
+In case that's hard to read, the part of the first line between
+``cat`` and ``bashrc`` is these five characters: space ( ), right
