## How to add device to pmbootstrap

```bash
PMAPORTS=~/.local/var/pmbootstrap/cache_git/pmaports
git clone https://github.com/MeexReay/pmos-xiaomi-angelican.git /tmp/pmosxan
mv -r /tmp/pmosxan/linux-xiaomi-angelican $PMAPORTS/device/testing
mv -r /tmp/pmosxan/device-xiaomi-angelican $PMAPORTS/device/testing
rm -r /tmp/pmosxan
```

## How to flash

Firstly, you need to unlock bootloader (See section below).

Enter fastboot mode (hold vol- and pwr buttons while turned off), and run this commands:

```bash
pmbootstrap init # if you didnt init yet
pmbootstrap install # if you havent done that yet
pmbootstrap flasher flash_rootfs # connect usb cable AFTER running
pmbootstrap flasher flash_kernel # connect usb cable AFTER running
pmbootstrap chroot fastboot reboot # connect usb cable AFTER running
```
