+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.
 
-[![Build Status](https://travis-ci.org/vu3rdd/functorrent.svg?branch=master)](https://travis-ci.org/vu3rdd/functorrent)
-
-## Building
-
-Functorrent can be build with [Stack](https://github.com/commercialhaskell/stack) or
-[Nix](https://nixos.org/nix/).
-
-### 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
-
 ### Usage
 
 If you invoke functorrent without any options, it expects the contents of a torrent file
 to be given in stdin. So
 
-$ cat ubuntu-14.10-desktop-amd64.iso.torrent | functorrent
-[....]
+    $ cat ubuntu-14.10-desktop-amd64.iso.torrent | functorrent
+    [....]
 
 Or one can explicitly specify the torrent file as input.
 
-$ functorrent ubuntu-14.10-desktop-amd64.iso.torrent
-[...]
+    $ functorrent ubuntu-14.10-desktop-amd64.iso.torrent
+    [...]

-## Current Status
+### WARNING
+
+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.
+
+### Current Status
+
+- most of the peer wire protocol works.
+- talks only to one peer at the moment.
+- can download files. But needs every piece to be served by the peer it connected to.
+- can talk to http/udp trackers.
+
+### TODO
 
-- can decode torrent files (bencoding)
-- talk to the tracker and get the peer list
-- the `main' program takes a torrent file (in the local file system) as input and
-  prints the {ip,port} for each peer, after talking to the tracker.
-- can handshake with the peer.
-- peer wire protocol (in progress)
+- Test suite.
+- Talk to multiple peers concurrently.
+- Piece download algorithms.
+- Multifile torrent support.
+- Magnet link support.
+- other advanced features of BitTorrent (like DHT).
 
-## TODO
+### Misc
 
-*    Test suite.
-*    Peer protocol (in progress).
-*    Get the file download working in the simplest possible way.
-*    Concurrency (threads per peer)
-*    other advanced features of Bit Torrent (like DHT).
+The Bangalore Haskell group forked an early version of this code and started to develop it as a group. My code has diverged a lot from it. Both are calling it functorrent. Perhaps that needs to be fixed.
