-### Boost
-
-CalChart uses Boost.  See boost.org for more information about what Boost is.  You will need to make sure it is installed on your system somewhere common so CMake can find it.  I recommend using brew to install it.  See https://brew.sh.

 ## Building CalChart:
 
 CalChart uses cmake to configure and run the platform specific build system.  For Mac we use Xcode.

-## Download Boost
-Visit http://www.boost.org/ and download the latest version of Boost. 
-Place the downloaded Boost directory somewhere on your computer:
-
-	e.g. c:\boost
-
-Remember where you place this Boost directory. In the next section, I will refer to the directory as $YOUR_BOOST_DIRECTORY. In the example above, $YOUR_BOOST_DIRECTORY = `c:\boost`
-
 ## Add environment variables
 Go to Control Panel->System->Advanced System Settings->Environment Variables
 Add the following User variables:
 
-	BOOST_DIR=$YOUR_BOOST_DIRECTORY
-	BOOST_ROOT=$YOUR_BOOST_DIRECTORY
-	Boost_INCLUDE_DIR=$YOUR_BOOST_DIRECTORY
 	CMAKE_PREFIX_PATH=$PATH_TO_BISON
 
-(see the `Download Boost` section above for the meaning of $YOUR_BOOST_DIRECTORY)
