+### 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_ez/default
+
+docker run -e keymap=gwen -e keyboard=ergodox_ez --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.

-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](VAGRANT_GUIDE.md).

@@ -372,17 +389,16 @@ But lets start with how to use it, first!
 
 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.
