+# proxmark3: the official Proxmark repository!
+
+The proxmark3 is a powerful general purpose RFID tool, the size of a deck
+of cards, designed to snoop, listen and emulate everything from
+**Low Frequency (125kHz)** to **High Frequency (13.56MHz)** tags.
+
+This repository contains enough software, logic (for the FPGA), and design
+documentation for the hardware that you could, at least in theory,
+do something useful with a proxmark3.
+
+## Resources

+   
+## Development
+
+The tools required to build  or run the project will vary depending on
+your operating system. Please refer to [the wiki](https://github.com/Proxmark/proxmark3/wiki) for details.
+
+## Obtaining hardware
+
+The Proxmark3 is available for purchase (assembled and tested) from the
+following locations:
+
+* [RyscCorp](https://proxmark3.com/) (US)
+* [Elechouse](http://www.elechouse.com/) (HK)
+* [Lab401](https://lab401.com/) (FR)
+* [RFxSecure](http://www.rfxsecure.com/) (SG)
+* [IceSQL](http://proxmark3.tictail.com/) (SE)

+Most of the ultra-low-volume contract assemblers could put
+something like this together with a reasonable yield. A run of around
+a dozen units is probably cost-effective. The BOM includes (possibly-
+outdated) component pricing, and everything is available from Digikey
+and the usual distributors.
+
+If you've never assembled a modern circuit board by hand, then this is
+not a good place to start. Some of the components (e.g. the crystals)
+must not be assembled with a soldering iron, and require hot air.
+
+The schematics are included; the component values given are not
+necessarily correct for all situations, but it should be possible to do
+nearly anything you would want with appropriate population options.
+
+The printed circuit board artwork is also available, as Gerbers and an
+Excellon drill file.
