Is there any “User Guide document” for IIO Oscilloscope (v0.99)


I'm using an ADRV9009 W/PCBZ board to test AD9009 chipset, and we use IIO Oscilloscope (v0.99) on windows. 

After IIO connects to the target board, I can see several devices listed ,

such as: "ad9528-1","adrv9009-phy","axi-adrv9009-tx-hpc","axi-adrv9009-rx-hpc"."axi-adrv9009-rx-obs-hpc".

The question is : 

1)  what's these "ad9528-1","adrv9009-phy","axi-adrv9009-tx-hpc","axi-adrv9009-rx-hpc"."axi-adrv9009-rx-obs-hpc means for ? 

2)  is there any document about  IIO Oscilloscope usage guide , to show me how to use IIO for the 9009 test and evaluation?
