+### Docker
+
+If this is a bit complex for you, Docker might be the turn-key solution you need. After installing [Docker](https://www.docker.com/products/docker), run the following command at the root of the QMK folder to build a keyboard/keymap:
+
+```bash
+# You'll run this every time you want to build a keymap
+# modify the keymap and keyboard assigment to compile what you want
+# defaults are ergodox/default
+
+docker run -e keymap=gwen -e keyboard=ergodox --rm -v $('pwd'):/qmk:rw edasque/qmk_firmware
+
+```
+
+This will compile the targetted keyboard/keymap and leave it in your QMK directory for you to flash.
+
### Vagrant
If you have any problems building the firmware, you can try using a tool called Vagrant. It will set up a virtual computer with a known configuration that's ready-to-go for firmware building. OLKB does NOT host the files for this virtual computer. Details on how to set up Vagrant are in the [VAGRANT_GUIDE file](doc/VAGRANT_GUIDE.md).
`CONSOLE_ENABLE`
-TODO
+This allows you to print messages that can be read using [`hid_listen`](https://www.pjrc.com/teensy/hid_listen.html). Add this to your `Makefile`, and set it to `yes`. Then put `println`, `printf`, etc. in your keymap or anywhere in the `qmk` source. Finally, open `hid_listen` and enjoy looking at your printed messages.
`COMMAND_ENABLE`
You can then override any settings, rather than having to copy and paste the whole thing.
-## Going beyond the keycodes
+# Going beyond the keycodes
Aside from the [basic keycodes](doc/keycode.txt), your keymap can include shortcuts to common operations.
+## Quick aliases to common actions
+
+Your keymap can include shortcuts to common operations (called "function actions" in tmk).
+
+These functions work the same way that their `ACTION_*` functions do - they're just quick aliases. To dig into all of the tmk `ACTION_*` functions, please see the [TMK documentation](https://github.com/jackhumbert/qmk_firmware/blob/master/doc/keymap.md#2-action).
+
+Instead of using `FNx` when defining `ACTION_*` functions, you can use `F(x)` - the benefit here is being able to use more than 32 function actions (up to 4096), if you happen to need them.
+
### Switching and toggling layers
`MO(layer)` - momentary switch to *layer*. As soon as you let go of the key, the layer is deactivated and you pop back out to the previous layer. When you apply this to a key, that same key must be set as `KC_TRNS` on the destination layer. Otherwise, you won't make it back to the original layer when you release the key (and you'll get a keycode sent). You can only switch to layers *above* your current layer. If you're on layer 0 and you use `MO(1)`, that will switch to layer 1 just fine. But if you include `MO(3)` on layer 5, that won't do anything for you -- because layer 3 is lower than layer 5 on the stack.
* `LCAG_T(kc)` - is CtrlAltGui when held and *kc* when tapped
* `MEH_T(kc)` - is like Hyper, but not as cool -- does not include the Cmd/Win key, so just sends Alt+Ctrl+Shift.

+## Space Cadet Shift: The future, built in
Steve Losh [described](http://stevelosh.com/blog/2012/10/a-modern-space-cadet/) the Space Cadet Shift quite well. Essentially, you hit the left Shift on its own, and you get an opening parenthesis; hit the right Shift on its own, and you get the closing one. When hit with other keys, the Shift key keeps working as it always does. Yes, it's as cool as it sounds.
This is just to keep the keyboard from going into command mode when you hold both Shift keys at the same time.
-### The Leader key: A new kind of modifier
+## The Leader key: A new kind of modifier
If you've ever used Vim, you know what a Leader key is. If not, you're about to discover a wonderful concept. :) Instead of hitting Alt+Shift+W for example (holding down three keys at the same time), what if you could hit a _sequence_ of keys instead? So you'd hit our special modifier (the Leader key), followed by W and then C (just a rapid succession of keys), and something would happen.
3. Within your `matrix_scan_user` function, do something like this:
```
+LEADER_EXTERNS();
+
void matrix_scan_user(void) {
LEADER_DICTIONARY() {
leading = false;
As you can see, you have three function. you can use - `SEQ_ONE_KEY` for single-key sequences (Leader followed by just one key), and `SEQ_TWO_KEYS` and `SEQ_THREE_KEYS` for longer sequences. Each of these accepts one or more keycodes as arguments. This is an important point: You can use keycodes from **any layer on your keyboard**. That layer would need to be active for the leader macro to fire, obviously.

-Hit the semicolon key once, send a semicolon. Hit it twice, rapidly -- send a colon. Hit it three times, and your keyboard's LEDs do a wild dance. That's just one example of what Tap Dance can do. It's one of the nicest community-contributed features in the firmware, conceived and created by [algernon](https://github.com/algernon) in [#451](https://github.com/jackhumbert/qmk_firmware/pull/451).

It's one of the nicest community-contributed features in the firmware, conceived and created by [algernon](https://github.com/algernon) in [#451](https://github.com/jackhumbert/qmk_firmware/pull/451). Here's how algernon describes the feature:
With this feature one can specify keys that behave differently, based on the amount of times they have been tapped, and when interrupted, they get handled before the interrupter.
First, you will need `TAP_DANCE_ENABLE=yes` in your `Makefile`, because the feature is disabled by default. This adds a little less than 1k to the firmware size. Next, you will want to define some tap-dance keys, which is easiest to do with the `TD()` macro, that - similar to `F()`, takes a number, which will later be used as an index into the `tap_dance_actions` array.
-This array specifies what actions shall be taken when a tap-dance key is in action. Currently, there are two possible options:
+This array specifies what actions shall be taken when a tap-dance key is in action. Currently, there are three possible options:
-* `ACTION_TAP_DANCE_DOUBLE(kc1, kc2)`: Sends the `kc1` keycode when tapped once, `kc2` otherwise.
-* `ACTION_TAP_DANCE_FN(fn)`: Calls the specified function - defined in the user keymap - with the current state of the tap-dance action.
+* `ACTION_TAP_DANCE_DOUBLE(kc1, kc2)`: Sends the `kc1` keycode when tapped once, `kc2` otherwise. When the key is held, the appropriate keycode is registered: `kc1` when pressed and held, `kc2` when tapped once, then pressed and held.
+* `ACTION_TAP_DANCE_FN(fn)`: Calls the specified function - defined in the user keymap - with the final tap count of the tap dance action.
+* `ACTION_TAP_DANCE_FN_ADVANCED(on_each_tap_fn, on_dance_finished_fn, on_reset_fn)`: Calls the first specified function - defined in the user keymap - on every tap, the second function on when the dance action finishes (like the previous option), and the last function when the tap dance action resets.
The first option is enough for a lot of cases, that just want dual roles. For example, `ACTION_TAP_DANCE(KC_SPC, KC_ENT)` will result in `Space` being sent on single-tap, `Enter` otherwise.
And that's the bulk of it!
-Do note, however, that this implementation does have some consequences: keys do not register until either they reach the tapping ceiling, or they time out. This means that if you hold the key, nothing happens, no repeat, no nothing. It is possible to detect held state, and register an action then too, but that's not implemented yet. Keys also unregister immediately after being registered, so you can't even hold the second tap. This is intentional, to be consistent.
-
And now, on to the explanation of how it works!
The main entry point is `process_tap_dance()`, called from `process_record_quantum()`, which is run for every keypress, and our handler gets to run early. This function checks whether the key pressed is a tap-dance key. If it is not, and a tap-dance was in action, we handle that first, and enqueue the newly pressed key. If it is a tap-dance key, then we check if it is the same as the already active one (if there's one active, that is). If it is not, we fire off the old one first, then register the new one. If it was the same, we increment the counter and the timer.
For the sake of flexibility, tap-dance actions can be either a pair of keycodes, or a user function. The latter allows one to handle higher tap counts, or do extra things, like blink the LEDs, fiddle with the backlighting, and so on. This is accomplished by using an union, and some clever macros.
-In the end, let's see a full example!
+### Examples
+
+Here's a simple example for a single definition:
+
+1. In your `makefile`, add `TAP_DANCE_ENABLE = yes`
+2. In your `config.h` (which you can copy from `qmk_firmware/keyboards/planck/config.h` to your keymap directory), add `#define TAPPING_TERM 200`
+3. In your `keymap.c` file, define the variables and definitions, then add to your keymap:
+
+```c
+//Tap Dance Declarations
+enum {
+ TD_ESC_CAPS = 0
+};
+
+//Tap Dance Definitions
+const qk_tap_dance_action_t tap_dance_actions[] = {
+ //Tap once for Esc, twice for Caps Lock
+ [TD_ESC_CAPS] = ACTION_TAP_DANCE_DOUBLE(KC_ESC, KC_CAPS)
+// Other declarations would go here, separated by commas, if you have them
+};
+
+//In Layer declaration, add tap dance item in place of a key code
+TD(TD_ESC_CAPS)
+```
+
+Here's a more complex example involving custom actions:
```c
enum {
CT_SE = 0,
CT_CLN,
- CT_EGG
+ CT_EGG,
+ CT_FLSH,
};
/* Have the above three on the keymap, TD(CT_SE), etc... */

-### Temporarily setting the default layer
+## Temporarily setting the default layer
`DF(layer)` - sets default layer to *layer*. The default layer is the one at the "bottom" of the layer stack - the ultimate fallback layer. This currently does not persist over power loss. When you plug the keyboard back in, layer 0 will always be the default. It is theoretically possible to work around that, but that's not what `DF` does.

## Macro shortcuts: Send a whole string when pressing just one key
Instead of using the `ACTION_MACRO` function, you can simply use `M(n)` to access macro *n* - *n* will get passed into the `action_get_macro` as the `id`, and you can use a switch statement to trigger it. This gets called on the keydown and keyup, so you'll need to use an if statement testing `record->event.pressed` (see keymap_default.c).
All of these functions are available in the `*_kb()` or `*_user()` variety. `kb` ones should only be used in the `<keyboard>/<keyboard>.c` file, and `user` ones should only be used in the `keymap.c`. The keyboard ones call the user ones - it's necessary to keep these calls to allow the keymap functions to work correctly.
-## `void martix_init_*(void)`
+## `void matrix_init_*(void)`
This function gets called when the matrix is initiated, and can contain start-up code for your keyboard/keymap.
"Rest style" in the method signature above (the last parameter) specifies if there's a rest (a moment of silence) between the notes.
