 README:
-  This file should be located at the top of the OpenJDK Mercurial repository
-  forest. This top or enclosing repository will include a "make" directory,
-  and a Makefile at the very top of the repository.
-  It should also include the 6 repositories: "jdk", "hotspot", "langtools",
-  "corba", "jaxws"  and "jaxp".
+  This file should be located at the top of the OpenJDK Mercurial root
+  repository. This root repository will include a "make" directory,
+  and a Makefile for building the entire OpenJDK.
+  A full OpenJDK repository set (forest) should also include the following
+  6 nested repositories:
+    "jdk", "hotspot", "langtools", "corba", "jaxws"  and "jaxp".
+  There are also several source downloads for the jax* repositories that
+  will be needed.
+
+  This one root repository can be obtained with something like:
+    hg clone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7
+  To make sure you have all the nested repositories, you can run:
+    cd openjdk7 && sh ./get_source.sh
+  (This is identical to using the Mercurial Forest Extension command 
+   'hg fclone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7').
+  People unfamiliar with Mercurial should read the first few chapters of
+  the Mercurial book: http://hgbook.red-bean.com/read/
 
   See http://openjdk.java.net/ for more information about the OpenJDK.
