+# INSTALLING DEPENDENCIES
+
+## Windows
+Download the following, and install in this order:
+  1. http://python.org/ftp/python/2.7.2/python-2.7.2.msi
+  2. http://pypi.python.org/packages/any/p/pyserial/pyserial-2.5.win32.exe
+  3. http://downloads.sourceforge.net/wxpython/wxPython2.8-win32-unicode-2.8.12.0-py27.exe
+  4. http://launchpad.net/pyreadline/trunk/1.7/+download/pyreadline-1.7.win32.exe
+
+## Ubuntu/Debian
+`sudo apt-get install python-serial python-wxgtk2.8`
+
+## Fedora 15
+`sudo yum install pyserial wxpython`
+
+## Mac OS X Lion
+
+  1. Ensure that the active Python is the system version.
+     (`brew uninstall python` or other appropriate incantations)
+  2. Download an install wxPython version 2.9-Carbon (its the Cocoa
+     version doesn't work)
+  3. Download and unpack pyserial from http://pypi.python.org/packages/source/p/pyserial/pyserial-2.5.tar.gz
+  4.  in a terminal, change to the folder you unzipped to, then type in:
+     `sudo python setup.py install`
+
+The tools will run just fine in 64bit on Lion, you don't need to mess
+with any of the 32bit settings
+
+## Mac OS X (pre Lion)
+Download and install:
+http://downloads.sourceforge.net/wxpython/wxPython2.8-osx-unicode-2.8.12.0-universal-py2.6.dmg
+Grab the source for pyserial from http://pypi.python.org/packages/source/p/pyserial/pyserial-2.5.tar.gz
+Unzip pyserial to a folder. Then, in a terminal, change to the folder you unzipped to, then type in:
+defaults write com.apple.versioner.python Prefer-32-Bit -bool yes
+sudo python setup.py install
+
+Alternatively, you can run python in 32 bit mode by setting the following environment variable before running the setup.py command:
+export VERSIONER_PYTHON_PREFER_32_BIT=yes
+
+Then repeat the same with http://launchpad.net/pyreadline/trunk/1.7/+download/pyreadline-1.7.zip
+
+# USING PRONTERFACE
+
+To use pronterface, you need:
+python (ideally 2.6.x or 2.7.x),
+pyserial (or python-serial on ubuntu/debian),
+pyreadline (not needed on Linux) and
+wxPython
+
+Download and install the above, and start pronterface.py
+Select the port name you are using from the first drop-down, select your baud rate, and hit connect.
+Load an STL (see the note on skeinforge below) or GCODE file, and you can upload it to SD or print it directly.
+The "monitor printer" function, when enabled, checks the printer state (temperatures, SD print progress) every 3 seconds.
+The command box recognizes all pronsole commands, but has no tabcompletion.
+
+If you want to load stl files, you need to put a version of skeinforge (doesn't matter which one) in a folder called "skeinforge".
+The "skeinforge" folder must be in the same folder as pronterface.py
+
+# USING PRONSOLE
+
+To use pronsole, you need:
+python (ideally 2.6.x or 2.7.x),
+pyserial (or python-serial on ubuntu/debian) and
+pyreadline (not needed on Linux)
+
+Start pronsole and you will be greeted with a command prompt. Type help to view the available commands.
+All commands have internal help, which you can access by typing "help commandname", for example "help connect"
+
+If you want to load stl files, you need to put a version of skeinforge (doesn't matter which one) in a folder called "skeinforge".
+The "skeinforge" folder must be in the same folder as pronsole.py
+
+# USING PRINTCORE
+
+To use printcore you need python (ideally 2.6.x or 2.7.x) and pyserial (or python-serial on ubuntu/debian)
+See pronsole for an example of a full-featured host, the bottom of printcore.py for a simple command-line
+sender, or the following code example:
+
+p=printcore('/dev/ttyUSB0',115200)
+p.startprint(data) # data is an array of gcode lines
+p.send_now("M105") # sends M105 as soon as possible
+p.pause()
+p.resume()
+p.disconnect()
