-## building
+## 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.
+
+
+    $ 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
 
-I suggest using cabal sandbox.
+If you invoke functorrent without any options, it expects the contents of a torrent file
+to be given in stdin. So
 
-### Steps:
+$ cat ubuntu-14.10-desktop-amd64.iso.torrent | functorrent
+[....]
 
-clone the repo; cd functorrent;
+Or one can explicitly specify the torrent file as input.
 
-    $ cabal sandbox init
-    $ wget http://www.stackage.org/lts/cabal.config
-    $ cabal install --only-dependencies --enable-tests
-    $ cabal build # binaries in ./dist/built/functorrent/*
+$ functorrent ubuntu-14.10-desktop-amd64.iso.torrent
+[...]
 
 ## Goals
 
+- [Optimized for Fun](http://www.slideshare.net/autang/ofun-optimizing-for-fun).
+  (should have called it "funtorrent")
 - Become more profient with Haskell.
 - Implement something non-trivial with Haskell (crypto, file operations, network
   operations, concurrency, bit twiddling, DHT).
-- Follow the spec - https://wiki.theory.org/BitTorrentSpecification
-- Easy for newbies like me to read and understand along side the spec.
+- Follow the spec ([official spec](http://bittorrent.org/beps/bep_0003.html), [unofficial spec](https://wiki.theory.org/BitTorrentSpecification))
+- Easy for newbies like me to read and understand alongside the spec.
 - doctest and quickcheck tests.
 - Follow Haskell Style Guide - https://github.com/tibbe/haskell-style-guide/blob/master/haskell-style.md

 *    Test suite.
-*    Peer protocol.
+*    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).
