-This project demonstrates how to stream data in and out of the Nexys A7's RAM. Vivado is used to build the demo's hardware platform, and Vitis is used to program the bitstream onto the board and to build and deploy a C application.+This project demonstrates how to stream data in and out of the Nexys A7's RAM.
  
-Additional information on how this demo can be used can be found in appropriate READMEs, linked below.+To use this demo, the Nexys A7-100T must be connected to a computer over MicroUSB, which must be running a serial terminal with a baud rate of 230400. 
 + 
 +Review statements printed over USB-UART for more information on how to operate this demo. FIXME pull anything from here into this document. 
 + 
 +This demo is a work in progress, and as such only supports WAV files with 96KHz sample rates. 8-bit and 16-bit audio is supported, but 16-bit data is truncated down to 8 bits, which may result in poor sound quality.
