 ## Building
 
-You will need the [bson-cxx](https://github.com/dwight/bson-cxx) library (a dependancy) to build the tools.  It is available on github.
-
-Place it as a peer level directory on disk with bsontools.  (That is you will see lines such as `#include "../../../bson-cxx/"` in the source code of these tools...)
+The [bson-cxx](https://github.com/dwight/bson-cxx) library (a dependancy) is added as a submodule to this project and should be availble when building the tools. 
+Initially cloning a repository with --recursive will clone the submodule as well.
 
 To build with scons, assuming it is installed, just type "scons".
