 I started writing a BitTorrent client because it seemed like fun and I am learning Haskell and wanted to see if I can write something real with Haskell than just heat the room. It is turning out to be a lot of fun.

-## Building
-
-Functorrent can be build with [Stack](https://github.com/commercialhaskell/stack) or
-[Nix](https://nixos.org/nix/). I personally test the build with Debian GNU/Linux and
-OS X using FP Complete's stack.
-
-### Stack
-
-Sandboxes give you per project independent containers, just like Python's
-virtualenv.
+### Building
 
+You need to install [Stack](https://github.com/commercialhaskell/stack), either via
+the OS package manager or via `cabal` (`cabal install stack`).
 
     $ git clone https://github.com/vu3rdd/functorrent && cd functorrent
     $ cabal install stack # or install stack by other means
     $ stack build # binaries in $(pwd)/.stack-work/install/x86..../lts-2.16/7.8.4/bin/functorrent
 
-### Building with Nix
-
-``$ nix-shell``` at the root of the source code repo should drop you into a
-shell which has all the package dependencies installed.

-    $ nix-shell --pure
-    [...]
-    [nix-shell] $ cabal configure && cabal build

-## Current Status
+### Current Status
 
 - most of the peer wire protocol works.
 - talks only to one peer at the moment. Single threaded.

-- this client is not usable as your daily BitTorrent client yet. You may get corrupted files and end up wasting a lot of bandwidth. So, until we achieve some robustness, consider this as a programmer-friendly project to learn about a bunch of stuff.
