The tutorial is pretty straightforward:

- Buy a USB-C wireless charging receiver; I used this one.
- Plug it into the Pro1's USB port and secure it to the back (I used double-sided tape to do so)
- Optionally, put a case on the back of the phone so the receiver is not exposed. Note that the case needs to be fairly thin for the receiver to work; I used a Huawei P20 Pro case which I no longer have a link for, but looks similar to this one.
