+Building with node-gyp
+----------------------
+
+You can build with node-gyp using the binding.gyp file, obviously this requires
+either the prebuilt tarball from npm or to do the above to generate it with the
+npmpkg target. Note the --target='' flag will not work since binding.gyp will
+do a check for the running node v8 version, you'll also need to run that
+version (or close to) in your $PATH.
