-The Glasgow Haskell Compiler
-============================
-
-This is the source tree for GHC, a compiler and interactive
-environment for the Haskell functional programming language.
-
-For more information, visit GHC's web site:
-
-  http://www.haskell.org/ghc/
-
-Information for developers of GHC can be found here:
-
-  http://hackage.haskell.org/trac/ghc/
-
-
-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 git
-  -------------------------------------
-
-  First get the GHC git repository:
-
-    $ git clone http://darcs.haskell.org/ghc.git/
-
-  Then run the sync-all script in that repository
-  to get the other repositories:
-
-     $ cd ghc
-     $ ./sync-all get
-
-  This checks out the "boot" packages.
-
-
-Building & Installing
-=====================
-
-For full information on building GHC, see the GHC Building Guide [3].
-Here follows a summary - if you get into trouble, the Building Guide
-has all the answers.
-
-Before building GHC you may need to install some other tools and
-libraries.  See "Setting up your system for building GHC" [8].
-
-NB. in particular you need GHC installed in order to build GHC,
-because the compiler is itself written in Haskell.  For instructions
-on how to port GHC to a new platform, see the Building Guide [3].
-
-For building library documentation, you'll need Haddock [6].  To build
-the compiler documentation, you need a good DocBook XML toolchain and
-dblatex.
-
-Quick start:  the following gives you a default build:
-
-    $ perl boot
-    $ ./configure
-    $ make
-    $ make install
-
-The "perl boot" step is only necessary if this is a tree checked out
-from git.  For source distributions downloaded from GHC's web site,
-this step has already been performed.
-
-These steps give you the default build, which includes everything
-optimised and built in various ways (eg. profiling libs are built).
-It can take a long time.  To customise the build, see the file HACKING.
-
-Once you have a build you need to keep it going.  You need to keep all
-repos in sync with the sync-all script [7].  To get the latest changes:
-
-    $ ./sync-all pull
-    $ ./sync-all get

+The Glasgow Haskell Compiler
+============================
+
+This is the source tree for [GHC] [1], a compiler and interactive
+environment for the Haskell functional programming language.
+
+For more information, visit [GHC's web site] [1].
+
+Information for developers of GHC can be found on the [GHC Trac] [2].
+
+
+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 git*
+
+  First clone the GHC github read-only repository:
+
+        $ git clone git://github.com/ghc/ghc.git
+
+  Then run the `sync-all` script in that repository to get the other repositories:
+
+        $ cd ghc
+        $ ./sync-all get
+
+  This checks out the "boot" packages.
+
+  **DO NOT submit pull request directly to the github repo.**
+  *See the GHC developer team's working conventions re [contributing patches](http://hackage.haskell.org/trac/ghc/wiki/WorkingConventions/Git#Contributingpatches "hackage.haskell.org/trac/ghc/wiki/WorkingConventions/Git#Contributingpatches").*
