+Getting the Source
+==================
+
+There are two ways to get a source tree:
+
+  1. Download source tarballs
+  ---------------------------
+
+  Download the GHC source distribution:
+
+      ghc-<version>-src.tar.bz2
+
+  which contains GHC itself and the "boot" libraries.
+
+  2. Check out the source code from darcs
+  ---------------------------------------
+
+  The recommended way to get a darcs checkout is to start off by
+  downloading a snapshot with a name like:
+
+      ghc-HEAD-2009-09-09-ghc-corelibs-testsuite.tar.bz2
+
+  from:
+
+      http://darcs.haskell.org/
+
+  and then untar it and bring it up-to-date with:
+
+     $ cd ghc
+     $ ./darcs-all get
+
+
+  Alternatively you can use darcs to get the repos, but it will take a
+  lot longer. First get the GHC darcs repository:
+
+    $ darcs get http://darcs.haskell.org/ghc/
+
+  Then run the darcs-all script in that repository
+  to get the other repositories:
+
+     $ cd ghc
+     $ chmod +x darcs-all
+     $ ./darcs-all get
+
+  This checks out the "boot" packages.
+

 Building & Installing
 =====================

 Quick start:  the following gives you a default build:

+    $ make install
