 Boost Endian library
 
 To experiment with the Endian library, various other boost libraries must be
-available. So you need to install a current version of Boost if you have not
+available. So you need to clone or install a current version of Boost if you
-already done so.
+have notalready done so.
 
 Boost.Endian is a header-only library, so there is no need to run a build
-for it, but these instructions run a bootstrap so that b2 is available.
+for it. These instructions do assume bootstrap has been run so that b2 is
-
+in your path environmental variable.
-These instructions assume you want to use a fresh copy of boost. If you are
-going to use an existing copy, skip the svn export and bootstrap steps.
