We don't have any user guide as such, but if you look at the code and look at the readme, it should not be especially difficult to get this working.

The basic points are to make sure that the bootloader is started by holding button 7 while resetting/powering on, and then run the command line application, using the parameters as explained in the readme.

Such as the DK,I can look at the DK user guide so that I would know how to use the DK.Do you have any document about the DFU such user guide?

Sorry,I have not described the problem clearly.Yes,I have looked at it,but I still don't know the procedure how to update my firmware.For example,I have program the bootloader and application into to 51822,or I just program the bootloader into the 51822,if I want to update the application,what is the procedure?by this way,I can see the firmware has been updated by UART.So I just want to know how to it.In other words,the code is ready in ask,how can I make the device firmware update demo used UART so that I can show other people the firmware can be updated by UART?

I guess this question came from me misunderstanding your other one, for which I'm sorry. However, I'd be happy if you could accept an answer, both here and in your other question.

If you are wondering how to do DFU over UART, you should look at the program and readme available in the Board\nrf6310\device_firmware_updates\experimental\hci_dfu_send_hex folder.

Also, the description of the packet format used is available here.
