+The [[https://atreus.technomancy.us/tmk][TMK firmware]] is
+recommended. You should be able to change into the =keyboard/atreus=
+directory and run =make KEYMAP=qwerty= (or whichever variant you want)
+to produce a qwerty =atreus.hex= file. You will probably want to
+create your own layout once you've gotten a chance to try it and see
+what works for you. See the readme for instructions of how to upload
+it to the keyboard's controller.
+
+There is also the older [[https://github.com/technomancy/atreus-firmware][atreus-firmware]] custom codebase which works
+but has fewer features. It is recommended mostly for learning purposes
+since the code is much simpler and easier to understand than TMK.
+
+** Bill of Materials
+
+If you don't want to get [[https://atreus.technomancy.us][the kit]] you can source parts yourself. (You
+can also order a partial kit if you want to customize some of the
+parts.) Using Cherry switches is cheapest unless you can find cheap
+Alps-mount keycaps:
+
+- 50 Matias or Cherry switches from mechanicalkeyboards.com
+- 50 diodes from radio shack, ebay, or whatever
+- 40 1x, 2 1.5x Keycaps from signatureplastics.com OR full keycap set from matias.com
+- A-star micro from pololu.com
+- Case materials from various sources
+- Case laser cutting: 7.5 minutes on a 100W Epilog laser; varies by source
+- USB micro cable, get anywhere
+
+Recommended but optional:
+
+- 5 linear Matias or Cherry switches
+
+The base keycap set from Signature Plastics only has one 1.5x key,
+which is used for the inner thumb keys. You can use a 1x key for one
+of them, but it looks kind of tacky, so I recommend getting a second
+1.5x keycap separately.
+
+*** Other Tools
+
+You'll need a soldering iron, solder, and a wire cutter. A multimeter
+can come in handy for testing the connections but is optional. You'll
+also need eight M3 machine screws with nuts; the length of the screws
+depends on the thickness of the acrylic you use. You can add rubber
+feet to the bottom to prevent the board from sliding around when
+placed on a desk. You'll also need sandpaper and lacquer for the
+wooden case.
+
+If you are building a hand-wired board you will also need a glue gun,
+hookup wire, and wire strippers.
+
+** Assembly
+
+See the [[https://atreus.technomancy.us/assembly.pdf][assembly instructions]] PDF.
+
+Hand-wired boards will want the [[https://atreus.technomancy.us/assembly-hand-wired.pdf][previous edition of the assembly instructions]].
+
+The LaTeX source to the assembly instructions is in the =assembly= directory.
