 # Setup
+
+#### Create a clean directory for roboto:
+
+```
+mkdir -p $HOME/roboto-src
+cd $HOME/roboto-src
+```
+
+#### Download the code and dependencies:
+
+```
+git clone https://github.com/google/roboto.git
+git clone https://github.com/behdad/fonttools.git
+git clone https://github.com/robofab-developers/robofab.git
+git clone https://github.com/jamesgk/feaTools.git
+git clone https://github.com/typemytype/booleanOperations.git
+```
+
+download [Cython](http://cython.org/#download) and extract it into
+the current directory.
+
+##### For OTF generation:
+
+```
+git clone https://github.com/typesupply/ufo2fdk.git
+```
+
+To build the FDK yourself:
+
+```
+git clone https://github.com/adobe-type-tools/afdko.git
+```
+
+download the latest version of Python 2.7
+[here](https://www.python.org/downloads/) and extract it into the current
+directory.
+
+If you're not building the FDK yourself, download the pre-built version
+[here](http://www.adobe.com/devnet/opentype/afdko.html) and unzip it into the
+current directory.
+
+##### For TTF generation, on Ubuntu:
+
+```
+sudo apt-get install fontforge python-fontforge
+```
+
+##### For post-production:
+
+```
+git clone https://code.google.com/p/noto/
+git clone https://github.com/rougier/freetype-py.git
+```
+
+download the latest tarball release of HarfBuzz [here](http://www.freedesktop.org/wiki/Software/HarfBuzz/) and extract it into the current directory.
+
+#### Install dependencies:
+
+```
+cd fonttools
+sudo python setup.py install
+cd ../robofab
+sudo python setup.py install
+cd ../feaTools
+sudo python setup.py install
+cd ../Cython-0.22
+sudo python setup.py install
+cd ../booleanOperations/cppWrapper
+sudo python setup.py build_ext --inplace
+cp pyClipper.so ../Lib/booleanOperations
+cd ..
+sudo python setup.py install
+cd ..
+```
+
+##### For OTF generation:
+
+```
+cd ufo2fdk
+sudo python setup.py install
+cd ..
+```
+
+If building the FDK yourself, follow the instructions in `afdko/FDK/FDK Build Notes.txt`:
+
+```
+cd Python-2.7
+
+# -- TODO necessary? --
+mv Modules/Setup.dist Modules/Setup
+# edit Modules/Setup to enable zlib, and readlines for osx and windows
+# --
+
+./configure --prefix=AFDKOPythonBuild
+make install
+mv AFDKOPythonBuild ../afdko/FDK/Tools/osx/Python
+cd ../fonttools
+sudo ../afdko/FDK/Tools/osx/Python/bin/python setup.py install
+cd ../afdko/FDK/Tools/Programs
+./BuildAll.sh
+cd ../..
+./FinishInstallOSX
+cd ../..
+```
+
+Otherwise:
+
+```
+cd FDK
+./FinishInstallOSX
+cd ..
+```
+
+In either case, use whatever install scripts and directory
+(`FinishInstall`[`OSX`|`Linux`|`Windows.cmd`],
+`BuildAll`[`.sh`|`Linux.sh`|`.cmd`],
+`FDK/Tools/`[`osx`|`linux`|`win`]) are appropriate for your platform (more
+detailed information can be found in `FDK/Read_Me_First.html`).
+
+##### For post-production:
+
+```
+cd harfbuzz
+./configure
+make
+sudo make install
+cd ../noto
+sudo python setup.py install
+cd ../freetype-py
+sudo python setup.py install
+cd ..
+```
+
+#### Running the toolchain:
+
+```
+cd roboto
+make
