-Dependent Types Branch of GHC
-=============================
+The Glasgow Haskell Compiler
+============================
 
-This is a fork of GHC, with work toward supporting dependent types.
-Anyone is welcome to download and play with this implementation,
-and I am happy to receive feedback and issue reports on GitHub.
+[![Build Status](https://api.travis-ci.org/ghc/ghc.svg?branch=master)](http://travis-ci.org/ghc/ghc)
 
-There are two options of using this branch:  manual, and Nix-based.
+This is the source tree for [GHC][1], a compiler and interactive
+environment for the Haskell functional programming language.
 
-Manual
-------
-
-This code should build, but I have tested it only on `DEBUG` settings;
-I recommend using build style `devel2` in `build.mk`.
-
-Here is a minimal script you can follow to build this at home;
-see the [GHC Building Guide] [3] for more info.
-
-~~~
-git clone https://github.com/goldfirere/ghc.git
-cd ghc
-git checkout nokinds
-git remote set-url origin git://git.haskell.org/ghc.git   # so submodules work
-git submodule update --init
-cd mk
-cp build.mk.sample build.mk
-## edit build.mk to uncomment the line to choose the `devel2` configuration
-cd ..
-perl boot
-./configure
-make
-~~~
-
-Check out the `testsuite/tests/dependent/should_compile` directory for
-a few sample programs that should compile on this fork of GHC.
-
-For more information about GHC, visit [GHC's web site][1].
+For more information, visit [GHC's web site][1].
 
 Information for developers of GHC can be found on the [GHC Trac][2].
 
-Nix-based
----------
-
-Thanks to @deepfire, this branch is available in Nixpkgs, which means that with
-some effort it can be fairly automatically employed to build any package from
-Hackage.  This way, though, requires that one installs the Nix package manager in
-parallel with the system package manager -- and this option is currently
-unavailable on Windows.
-
-Here are the instructions:
-
-1. To install the Nix package manager, taking over /nix for package storage:
-
-        curl https://nixos.org/nix/install | sh
-
-2. Make Nix use the `master` repository of Nixpkgs package definitions:
 
-    	git clone https://github.com/NixOS/nixpkgs.git
-    	pushd ~/.nix-defexpr
-    	rm -rf channels
-    	ln -s ../nixpkgs
-    	popd
-    	echo 'export NIX_PATH=nixpkgs=/home/---<USERNAME>---/nixpkgs' >> ~/.bashrc
-    	export NIX_PATH=nixpkgs=/home/---<USERNAME>---/nixpkgs
+Getting the Source
+==================
 
-3. [OPTIONAL] To enable prebuilt binaries from Peter Simons/NixOS Hydra servers:
+There are two ways to get a source tree:
 
-    	sudo mkdir /etc/nix
-    	echo 'binary-caches = http://hydra.nixos.org/ http://hydra.cryp.to/' | sudo dd of=/etc/nix/nix.conf
+ 1. *Download source tarballs*
 
-    	# If you don't do that, everything will still work, just it'll have
-    	# to build everything from source.
+  Download the GHC source distribution:
 
-4. Enter a shell with `ghc-nokinds` available:
+        ghc-<version>-src.tar.bz2
 
-        nix-shell -p haskell.compiler.ghcNokinds
+  which contains GHC itself and the "boot" libraries.
 
-5. See it's indeed `nokinds`:
+ 2. *Check out the source code from git*
 
-    	wget https://raw.githubusercontent.com/goldfirere/ghc/nokinds/testsuite/tests/dependent/should_compile/KindEqualities2.hs
-    	runhaskell KindEqualities2.hs
+        $ git clone --recursive git://git.haskell.org/ghc.git
 
-To apply 'nokinds' to building packages from Hackage, the best option would be
-to follow instructions from the "Nix loves Haskell" talk by Peter Simons:
+  Note: cloning GHC from Github requires a special setup. See [Getting a GHC
+  repository from Github] [7].
 
-   http://cryp.to/nixos-meetup-3-slides.pdf
+  **DO NOT submit pull request directly to the github repo.**
+  *See the GHC team's working conventions re [how to contribute a patch to GHC](http://ghc.haskell.org/trac/ghc/wiki/WorkingConventions/FixingBugs "ghc.haskell.org/trac/ghc/wiki/WorkingConventions/FixingBug").*
 
-..where the relevant compiler name would be "ghcNokinds".
