+# Command (Formerly known as Magic)
+
+Command is a way to change your keyboard's behavior without having to flash or unplug it to use [Bootmagic](feature_bootmagic.md). There is a lot of overlap between this functionality and the [Bootmagic Keycodes](feature_bootmagic.md). Whenever possible we encourage you to use that functionality instead of Command.
+
+## Enabling Command
+
+By default Command is disabled. You can enable it in your `rules.mk` file:
+
+    COMMAND_ENABLE = yes
+
+## Usage
+
+To use Command you hold down the key combination defined by `IS_COMMAND`. By default that combination is both shift keys. While holding the key combination press the key corresponding to the command you want.
+
+For example, to write the current QMK version to the QMK Toolbox console, you can press `Left Shift`+`Right Shift`+`V`.
+
+## Configuration
+
+The following values can be defined in `config.h` to control the behavior of Command.
+
+|Define |Default | Description |
+|-------|--------|-------------|
+|`IS_COMMAND()`                      |`(keyboard_report->mods == (MOD_BIT(KC_LSHIFT) | MOD_BIT(KC_RSHIFT)))`|Key combination to activate Command|
