 Please note the USB port can only supply a limited amount of power to the keyboard (500mA by standard, however, modern computer and most usb hubs can provide 700+mA.). According to the data of NeoPixel from Adafruit, 30 WS2812 LEDs require a 5V 1A power supply, LEDs used in this mod should not more than 20.

+## Safety Considerations
+
+You probably don't want to "brick" your keyboard, making it impossible
+to rewrite firmware onto it.  Here are some of the parameters to show
+what things are (and likely aren't) too risky.
+
+- If a keyboard map does not include RESET, then, to get into DFU
+  mode, you will need to press the reset button on the PCB, which
+  requires unscrewing some bits.
+- Messing with tmk_core / common files might make the keyboard
+  inoperable
+- Too large a .hex file is trouble; `make dfu` will erase the block,
+  test the size (oops, wrong order!), which errors out, failing to
+  flash the keyboard
+- DFU tools do /not/ allow you to write into the bootloader (unless
+  you throw in extra fruitsalad of options), so there is little risk
+  there.
+- EEPROM has around a 100000 write cycle.  You shouldn't rewrite the
+  firmware repeatedly and continually; that'll burn the EEPROM
+  eventually.

-## Quick aliases to common actions
-
-Your keymap can include shortcuts to common operations (called "function actions" in tmk).
-
-### 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.
-
-`LT(layer, kc)` - momentary switch to *layer* when held, and *kc* when tapped. Like `MO()`, this only works upwards in the layer stack (`layer` must be higher than the current layer).
-
-`TG(layer)` - toggles a layer on or off. As with `MO()`, you should set this key as `KC_TRNS` in the destination layer so that tapping it again actually toggles back to the original layer. Only works upwards in the layer stack.
-
-### Fun with modifier keys
-
-* `LSFT(kc)` - applies left Shift to *kc* (keycode) - `S(kc)` is an alias
-* `RSFT(kc)` - applies right Shift to *kc*
-* `LCTL(kc)` - applies left Control to *kc*
-* `RCTL(kc)` - applies right Control to *kc*
-* `LALT(kc)` - applies left Alt to *kc*
-* `RALT(kc)` - applies right Alt to *kc*
-* `LGUI(kc)` - applies left GUI (command/win) to *kc*
-* `RGUI(kc)` - applies right GUI (command/win) to *kc*
-
-You can also chain these, like this:
-
-    LALT(LCTL(KC_DEL)) -- this makes a key that sends Alt, Control, and Delete in a single keypress.
-
-The following shortcuts automatically add `LSFT()` to keycodes to get commonly used symbols. Their long names are also available and documented in `/quantum/keymap_common.h`.
-
-    KC_TILD  ~
-    KC_EXLM  !
-    KC_AT    @
-    KC_HASH  #
-    KC_DLR   $
-    KC_PERC  %
-    KC_CIRC  ^

-
-`MT(mod, kc)` - is *mod* (modifier key - MOD_LCTL, MOD_LSFT) when held, and *kc* when tapped. In other words, you can have a key that sends Esc (or the letter O or whatever) when you tap it, but works as a Control key or a Shift key when you hold it down. 
-
-These are the values you can use for the `mod` in `MT()` (right-hand modifiers are not available):
-
-  * MOD_LCTL
-  * MOD_LSFT
-  * MOD_LALT
-  * MOD_LGUI
-
-These can also be combined like `MOD_LCTL | MOD_LSFT` e.g. `MT(MOD_LCTL | MOD_LSFT, KC_ESC)` which would activate Control and Shift when held, and send Escape when tapped.
-
-We've added shortcuts to make common modifier/tap (mod-tap) mappings more compact:
-
-  * `CTL_T(kc)` - is LCTL when held and *kc* when tapped 
-  * `SFT_T(kc)` - is LSFT when held and *kc* when tapped 
-  * `ALT_T(kc)` - is LALT when held and *kc* when tapped 
-  * `GUI_T(kc)` - is LGUI when held and *kc* when tapped 
-  * `ALL_T(kc)` - is Hyper (all mods) when held and *kc* when tapped. To read more about what you can do with a Hyper key, see [this blog post by Brett Terpstra](http://brettterpstra.com/2012/12/08/a-useful-caps-lock-key/)
-
-### 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.
-
-### Remember: These are just aliases
-
-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/tmk_core/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.
-
-## 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 keymaps/default.c).
-
-```c
-const macro_t *action_get_macro(keyrecord_t *record, uint8_t id, uint8_t opt) // this is the function signature -- just copy/paste it into your keymap file as it is.
-{
-  switch(id) {
-    case 0: // this would trigger when you hit a key mapped as M(0)
-      if (record->event.pressed) {
-        return MACRO( I(255), T(H), T(E), T(L), T(L), W(255), T(O), END  ); // this sends the string 'hello' when the macro executes
-      } 
-      break;
-  }
-  return MACRO_NONE;
-};
-```
-A macro can include the following commands:
-
-* I() change interval of stroke in milliseconds.
-* D() press key.
-* U() release key.
-* T() type key(press and release).
-* W() wait (milliseconds).
-* END end mark.
-
-So above you can see the stroke interval changed to 255ms between each keystroke, then a bunch of keys being typed, waits a while, then the macro ends.
-
-Note: Using macros to have your keyboard send passwords for you is a bad idea.
-
-### Additional keycode aliases for software-implemented layouts (Colemak, Dvorak, etc)
-
-Everything is assuming you're in Qwerty (in software) by default, but there is built-in support for using a Colemak or Dvorak layout by including this at the top of your keymap:
-
-   #include "keymap_<layout>.h"
-
-Where <layout> is "colemak" or "dvorak". After including this line, you will get access to:
- 
- * `CM_*` for all of the Colemak-equivalent characters
- * `DV_*` for all of the Dvorak-equivalent characters
- 
-These implementations assume you're using Colemak or Dvorak on your OS, not on your keyboard - this is referred to as a software-implemented layout. If your computer is in Qwerty and your keymap is in Colemak or Dvorak, this is referred to as a firmware-implemented layout, and you won't need these features. 
-
-To give an example, if you're using software-implemented Colemak, and want to get an `F`, you would use `CM_F` - `KC_F` under these same circumstances would result in `T`.
-
-## Additional language support
-
-In `quantum/keymap_extras/`, you'll see various language files - these work the same way as the alternative layout ones do. Most are defined by their two letter country/language code followed by an underscore and a 4-letter abbreviation of its name. `FR_UGRV` which will result in a `ù` when using a software-implemented AZERTY layout. It's currently difficult to send such characters in just the firmware (but it's being worked on - see Unicode support).
-
-## Unicode support
-
-You can currently send 4 hex digits with your OS-specific modifier key (RALT for OSX with the "Unicode Hex Input" layout) - this is currently limited to supporting one OS at a time, and requires a recompile for switching. 8 digit hex codes are being worked on. The keycode function is `UC(n)`, where *n* is a 4 digit hexidecimal. Enable from the Makefile.
-
-## Other firmware shortcut keycodes
-
-* `RESET` - puts the MCU in DFU mode for flashing new firmware (with `make dfu`)
-* `DEBUG` - the firmware into debug mode - you'll need hid_listen to see things
-* `BL_ON` - turns the backlight on
-* `BL_OFF` - turns the backlight off
-* `BL_<n>` - sets the backlight to level *n*
-* `BL_INC` - increments the backlight level by one
-* `BL_DEC` - decrements the backlight level by one
-* `BL_TOGG` - toggles the backlight
-* `BL_STEP` - steps through the backlight levels
-
-Enable the backlight from the Makefile.
-
-## MIDI functionalty
-
-This is still a WIP, but check out `quantum/keymap_midi.c` to see what's happening. Enable from the Makefile.
-
-## Bluetooth functionality
-
-This requires [some hardware changes](https://www.reddit.com/r/MechanicalKeyboards/comments/3psx0q/the_planck_keyboard_with_bluetooth_guide_and/?ref=search_posts), but can be enabled via the Makefile. The firmware will still output characters via USB, so be aware of this when charging via a computer. It would make sense to have a switch on the Bluefruit to turn it off at will.
