* Keyboard plate (metal, plastic, cardboard, etc)
* Wire (strained for wiring to the Teensy, anything for the rows/columns)
* Soldering iron set at 600ºF or 315ºC (if temperature-controlled)
-* Resin-cored solder (leaded or lead-free)
+* Rosin-cored solder (leaded or lead-free)
* Adequate ventilation/a fan
* Tweezers (optional)
* Wire cutters/snippers
Notice how the `k11` and `KC_NO` switched places to represent the wiring, and the unused final column on the bottom row. Sometimes it'll make more sense to put a keyswitch on a particular column, but in the end, it won't matter, as long as all of them are accounted for. You can use this process to write out the `KEYMAP` for your entire keyboard - be sure to remember that your keyboard is actually backwards when looking at the underside of it.
-### keymaps/default.c
+### keymaps/<variant>/default.c
-This is the actual keymap for your keyboard, and the main place you'll make changes as you perfect your layout. `default.c` is the file that gets pull by default when typing `make`, but you can make other files as well, and specify them by typing `make KEYMAP=<variant>`, which will pull `keymaps/<variant>.c`.

The basis of a keymap is its layers - by default, layer 0 is active. You can activate other layers, the highest of which will be referenced first. Let's start with our base layer.
