 # Fipsy FPGA Programmer for ESP32
 
-**esp-fipsy** library allows programming a [Fipsy FPGA breakout board](https://www.mocomakers.com/fipsy-fpga/) from an ESP32 microcontroller.
-[TcpFipsyLoader](examples/TcpFipsyLoader/) demonstrates how to use this library.
+**esp-fipsy** library allows programming a [Fipsy FPGA breakout board](https://www.fipsyfpga.com/) from an ESP32 microcontroller.
+
+This library can be used in the Arduino IDE.
+
+When using this project directly:
+1. Visit the documentation for the ESP32 programmer on [https://www.fipsyfpga.com](https://www.fipsyfpga.com)
+2. Program the ESP32 as a programmer using the [TcpFipsyLoader](examples/TcpFipsyLoader/). This file demonstrates how to use this library.
+3. Once you have the IP address for the ESP32 use the [sendJed.py](scripts/sendJed.py) file to program the device. For example:
+
+```
+python sendJed.py --file "C:\Users\myuser\Projects\Fipsy-FPGA-edu\Examples\FipsyV2 - XO2-1200\1. Blinky\project_files\Implementation\FipsyBaseline_Implementation.jed" 192.168.1.194
+```
+
+For more information please see: [FipsyFPGA.com](https://www.fipsyfpga.com)
