 Build phase
 -----------
 
+Specify the Manylinux version to build for with the `MB_ML_VER` environment variable.  The default version is `1`.  Versions that are currently valid are:
+
+* `1` (see [PEP 513](https://www.python.org/dev/peps/pep-0513);
+* `2010` (see [PEP
+  571](https://www.python.org/dev/peps/pep-0571).
+
+At some point `2014` will be a valid version - see [PEP

+
+The environment variable specified which Manylinux docker container you are building in.
+
+The `PLAT` environment variable can be one of `x86_64` or `i686`, specifying 64-bit and 32-bit builds, respectively.  The default is 64-bit.
+
+At the time of writing, Manylinux2010 only supports 64-bit
+builds, so `MB_ML_VER=2010` and `PLAT=i686` is an invalid
+combination, and will generate an error when trying to find the
+matching Docker image.
