+
+## Summary
+
+The bluetooth behavior allows management of various settings and states related to the bluetooth connection(s)
+between the keyboard and the host. By default, ZMK supports five "profiles" for selecting which bonded host
+computer/laptop/keyboard should receive the keyboard input; many of the commands here operation on those profiles.
+
+## Bluetooth Command Defines
+
+Bluetooth command defines are provided through the [`dt-bindings/zmk/bt.h`](https://github.com/zmkfirmware/zmk/blob/main/app/include/dt-bindings/zmk/bt.h) header,
+which is added at the top of the keymap file:
+
+```
+#include <dt-bindings/zmk/bt.h>
+```
+
+This will allow you to reference the actions defined in this header such as `BT_CLR_CMD`.
+
+Here is a table describing the command for each define:
+
+| Define       | Action                                                                                         |
+| ------------ | ---------------------------------------------------------------------------------------------- |
+| `BT_CLR_CMD` | Clear bond information between the keyboard and host for the selected profile.                 |
+| `BT_NXT_CMD` | Switch to the next profile, cycling through to the first one when the end is reached.          |
+| `BT_PRV_CMD` | Switch to the previous profile, cycling through to the last one when the beginning is reached. |
+| `BT_SEL_CMD` | Select the 0-indexed profile by number.                                                        |
+
+Because at least one bluetooth commands takes an additional parameter, it is recommended to use
+the following aliases in your keymap to avoid having to specify an ignored second parameter:
+
+| Define   | Action                                                                           |
+| -------- | -------------------------------------------------------------------------------- |
+| `BT_CLR` | Alias for `BT_CLR_CMD 0` to clear the current profile's bond to the current host |
+| `BT_NXT` | Alias for `BT_NXT_CMD 0` to select the next profile                              |
+| `BT_PRV` | Alias for `BT_PRV_CMD 0` to select the previous profile                          |
+| `BT_SEL` | Alias for `BT_SEL_CMD` to select the given profile, e.g. `&bt BT_SEL 1`          |
+
+## Bluetooth Behavior
+
+The bluetooth behavior completes an bluetooth action given on press.
+
+### Behavior Binding
+
+- Reference: `&bt`
+- Parameter #1: The bluetooth command define, e.g. `BT_CLR_CMD`
+- Parameter #2: (Reserved for future bluetooth command types)
+
+### Examples
+
+1. Behavior binding to clear the paired host for the selected profile:
+
+   ```
+   &bt BT_CLR
+   ```
+
+1. Behavior binding to select the next profile:
+
+   ```
+   &bt BT_NXT
+   ```
+
+1. Behavior binding to select the previous profile:
+
+   ```
+   &bt BT_PRV
+   ```
+
+1. Behavior binding to select the 2nd profile (passed parameters are [zero based](https://en.wikipedia.org/wiki/Zero-based_numbering)):
+
+   ```
+   &bt BT_SEL 1
+   ```
