-## `SEND_STRING()` & `process_record_user`
+## Using Macros In JSON Keymaps
+
+You can define up to 32 macros in a `keymap.json` file, as used by [Configurator](newbs_building_firmware_configurator.md), and `qmk compile`. You can define these macros in a list under the `macros` keyword, like this:
+
+```json
+{
+    "keyboard": "handwired/my_macropad",
+    "keymap": "my_keymap",
+    "macros": [
+        [
+            {"action":"down", "keycodes": ["LSFT"]},
+            "hello world1",
+            {"action": "up","keycodes": ["LSFT"]}
+        ],
+        [
+            {"action":"tap", "keycodes": ["LCTL", "LALT", "DEL"]}
+        ],
+        [
+            "ding!",
+            {"action":"beep"}
+        ],
+        [
+            {"action":"tap", "keycodes": ["F1"]},
+            {"action":"delay", "duration": "1000"},
+            {"action":"tap", "keycodes": ["PGDN"]}
+        ]
+    ],
+    "layout": "LAYOUT_all",
+    "layers": [
+        ["MACRO_0", "MACRO_1", "MACRO_2", "MACRO_3"]
+    ]
+}
+```
+
+### Selecting Your Host Keyboard Layout
+
+If you type in a language other than English, or use a non-QWERTY layout like Colemak, Dvorak, or Workman, you may have set your computer's input language to match this layout. This presents a challenge when creating macros- you may need to type different keys to get the same letters! To address this you can add the `host_language` key to your keymap.json, like so:
+
+```json
+{
+    "keyboard": "handwired/my_macropad",
+    "keymap": "my_keymap",
+    "host_layout": "dvorak",
+    "macros": [
+        ["Hello, World!"]
+    ],
+    "layout": "LAYOUT_all",
+    "layers": [
+        ["MACRO_0"]
+    ]
+}
+```
+
+The current list of available languages is:
+
+| belgian | bepo | br_abnt2 | canadian_multilingual |
+|:-------:|:----:|:--------:|:---------------------:|
+| **colemak** | **croatian** | **czech** | **danish** |

+| **italian_osx_iso** | **jis** | **latvian** | **lithuanian_azerty** |

+| **workman** | **workman_zxcvm** |
+
+### Macro Basics
+
+Each macro is an array consisting of strings and objects (dictionaries.) Strings are typed to your computer while objects allow you to control how your macro is typed out.
+
+#### Object Format
+
+All objects have one required key: `action`. This tells QMK what the object does. There are currently 5 actions: beep, delay, down, tap, up
+
+Only basic keycodes (prefixed by `KC_`) are supported. Do not include the `KC_` prefix when listing keycodes.
+
+* `beep`
+    * Play a bell if the keyboard has [audio enabled](feature_audio.md).
+    * Example: `{"action": "beep"}`
+* `delay`
+    * Pause macro playback. Duration is specified in milliseconds (ms).
+    * Example: `{"action": "delay", "duration": 500}`
+* `down`
+    * Send a key down event for one or more keycodes.
+    * Example, single key: `{"action":"down", "keycodes": ["LSFT"]}`
+    * Example, multiple keys: `{"action":"down", "keycodes": ["CTRL", "LSFT"]}`
+* `tap`
+    * Type a chord, which sends a down event for each key followed by an up event for each key.
+    * Example, single key: `{"action":"tap", "keycodes": ["F13"]}`
+    * Example, multiple keys: `{"action":"tap", "keycodes": ["CTRL", "LALT", "DEL"]}`
+* `up`
+    * Send a key up event for one or more keycodes.
+    * Example, single key: `{"action":"up", "keycodes": ["LSFT"]}`
+    * Example, multiple keys: `{"action":"up", "keycodes": ["CTRL", "LSFT"]}`

 Sometimes you want a key to type out words or phrases. For the most common situations, we've provided `SEND_STRING()`, which will type out a string (i.e. a sequence of characters) for you. All ASCII characters that are easily translatable to a keycode are supported (e.g. `qmk 123\n\t`).

+### Advanced Macro Functions
 
 There are some functions you may find useful in macro-writing. Keep in mind that while you can write some fairly advanced code within a macro, if your functionality gets too complex you may want to define a custom keycode instead. Macros are meant to be simple.
 
 ?> You can also use the functions described in [Useful function](ref_functions.md) and [Checking modifier state](feature_advanced_keycodes#checking-modifier-state) for additional functionality. For example, `reset_keyboard()` allows you to reset the keyboard as part of a macro and `get_mods() & MOD_MASK_SHIFT` lets you check for the existence of active shift modifiers.

 These functions work similar to their regular counterparts, but allow you to use modded keycodes (with Shift, Alt, Control, and/or GUI applied to them).
