+* [TeleMetrum](TeleMetrum/)
+is our primary project, a dual-deploy rocketry altimeter with improved sensor
+complement and bidirectional RF telemetry link.
+
+* [TeleDongle](TeleDongle/)
+is a simple RF interface for use in ground stations interacting with rockets
+using [TeleMetrum](TeleMetrum/). It may also be useful as a generic RF
+interface for other microcontroller systems.
+
+* [AltOS](AltOS/)
+is the name of the firmware and related utilities that Keith maintains for
+the set of hardware projects here.
+
+* [TelePyro](TelePyro/) is a planned 8-channel pyro expansion board for
+[TeleMetrum](TeleMetrum/).
+
+* [TeleTerra](TeleTerra) is a planned hand-held ground station for use with
+[TeleMetrum](TeleMetrum/).
+
+* [AltusMetrum](AltusMetrum/)
+was Bdale's original project here, a dual-deploy rocketry altimeter. One
+prototype was built, but never flown. This project is now indefinitely on hold.

+# Getting Involved #
+
+If you aren't already playing with model rockets, that's a good place to
+start. Finding a local [NAR Section](http://nar.org/NARsect.html) or
+[Tripoli](http://tripoli.org) Prefecture is a good idea, since you can
+learn a lot and see some great flights by showing up at a club launch.
+
+As we make progress, you can read about it in our [News](News) feed.
+We also hang out on IRC channel #altusmetrum on irc.oftc.net if you have
+questions that aren't answered here.
