-# eprom-prog
+# EPROM Burner
 
-This repository will provide a circuit and the source code to implement a EPROM programer.
+Here you will find the circuit and the source code for a EPROM burner/programer.
+This project can be used to program the famous 27/27Cxxx EPROM family.
+With this circuit and software you will be able to write and read from an EPROM.
+
+Additional to the provided hardware you will need a Arduino MEGA.
+The provided circuit is easy to solder by our own with through hole components - no SMD soldering required!
+I have some spare PCBs, you can contact me to get some.
 
 ## schematic
 
-You can find the Eagle schematic in the schematic folder.
-To the hardware for this project, you will need a Arduino MEGA board.
+You can find the Eagle schematic in the 'schematic' folder.
+Aditional you will need a Arduino MEGA board.
 
 ## source code
 
-tbd
+The source code can be found in the folder 'src', 'AVRhal' and some test-programs in 'test'.
+The build system is cmake.
+
+### compile
+
+To compile the source code follow this steps:
+
+   mkdir build && cd build
+   cmake ..
+   make
+   
+### flash the AVR/Arduino
+
+   make upload_EPROM-PROG
+
+## supported EPROMs
