 Since the FPGA is very old,  the Xilinx WebPack ISE 10.1  is the last working tool chain.  You can download this legacy development on Xilinx and register for a free product installation id.
 Or use mine  `11LTAJ5ZJK3PXTUBMF0C0J6C4`    The package to download is about 7Gb and linux based.   Though I recently managed to install it on WSL for Windows 10.
 
+There is a docker image with webpack built in which has been built which you can use to easily compile the images:
+
+```
+docker pull nhutton/prox-container:webp_image_complete
+docker run -v <LOCAL_PATH>/proxmark3:/tmp --rm -it nhutton/prox-container:webp_image_complete bash
+$ cd /tmp/proxmark/fpga
+$ make all
+```

 In order to save space,  these fpga images are LZ4 compressed and included in the fullimage.elf file when compiling the ARM SRC.  `make armsrc`
 This means we save some precious space on the ARM but its a bit more complex when flashing to fpga since it has to decompress on the fly.
