+
+### [Debian](/contrib/debian) ###
+Contains files used to package bitcoind/bitcoin-qt
+for Debian-based Linux systems. If you compile bitcoind/bitcoin-qt yourself, there are some useful files here.
+
+### [Gitian-descriptors](/contrib/gitian-descriptors) ###
+Gavin's notes on getting gitian builds up and running using KVM.
+
+### [Gitian-downloader](/contrib/gitian-downloader)
+Various PGP files of core developers. 
+
+### [Macdeploy](/contrib/macdeploy) ###
+Scripts and notes for Mac builds. 
+
+### [PyMiner](/contrib/pyminer) ###
+
+This is a 'getwork' CPU mining client for Bitcoin. It is pure-python, and therefore very, very slow.  The purpose is to provide a reference implementation of a miner, for study.
+
+### [Qos](/contrib/qos) ###
+
+A Linux bash script that will set up tc to limit the outgoing bandwidth for connections to the Bitcoin network. This means one can have an always-on bitcoind instance running, and another local bitcoind/bitcoin-qt instance which connects to this node and receives blocks from it.
+
+### [Seeds](/contrib/seeds) ###
+Utility to generate the pnSeed[] array that is compiled into the client.
+
+### [SpendFrom](/contrib/spendfrom) ###
+
+Use the raw transactions API to send coins received on a particular
+address (or addresses).
+
+### [TestGen](/contrib/testgen) ###
+Utilities to generate test vectors for the data-driven Bitcoin tests.
