* Allow reset behavior to have a type property.
* Add `bootloader` node that triggers DFU UF2
  bootloader mode using the AdaFruit nrf52
  bootloader.

title: Reset Behaviors
sidebar_label: Reset

## Summary
There are two available behaviors that can be used to trigger a reset of the keyboard.
The first is a soft reset, that will simply reset and re-run the currently flashed
firmware; the second when triggered will reset into the bootloader, allowing you to
flash a new firmware to the keyboard.
## Reset
The basic reset behavior will reset the keyboard and re-run the firmware flashed
to the device
### Behavior Binding
- Reference: `&reset`
- Parameters: None
Example:
```
&reset
```
## Bootloader Reset
The bootloader reset behavior will reset the keyboard and put it into bootloader mode, allowing
you to flash a new firmware.
### Behavior Binding
- Reference: `&bootloader`
- Parameters: None
Example:
```
&bootloader
```
