1. Install doxygen:

* Use homebrew to install: `brew install doxygen`. The executable will be

installed in `/usr/local/bin` which is already in your path.

* Alternatively, install from here: [doxygen](http://www.stack.nl/~dimitri/doxygen/download.html).

You'll then need to make doxygen available to your command line. You can

do this by adding a symbolic link from `/usr/local/bin` to the doxygen

executable. For example, `$ ln -s /Applications/Doxygen.app/Contents/Resources/doxygen /usr/local/bin/doxygen`

2. Install [Boost](http://www.boost.org/users/download/)

1. Extract the compressed file contents to your (new) `$BOOST_ROOT` location.

2. Open a command prompt or shell in the `$BOOST_ROOT`.

3. `$ ./bootstrap.bat`

4. (Optional, if you also plan to build rippled)

`$ ./b2 toolset=clang threading=multi runtime-link=static link=static

cxxflags="-stdlib=libc++" linkflags="-stdlib=libc++" adress-model=64`

5. If it is not already there, add your `$BOOST_ROOT` to your environment

`$PATH`. This makes the `b2` command available to the command line.

3. That should be all that's required. In OS X 10.11, at least, libxml2 and

libxslt come pre-installed.
