 You can now use cctl-prog to download your payload code.
+A prebuilt version of cctl-prog.exe is provided for Windows. For Linux or OSX, type "make".
 
 For usage instructions, run cctl-prog with no arguments:
 
 `./cctl-prog`
 
+    ChipCon Tiny Loader Programmer
+    cctl-prog -d /dev/ttyXYZ [-c] [-f file.hex]
+    --help           -h          This help
+    --console        -c          Connect console to serial port on device
+    --flash=file.hex -f file.hex Reflash device with intel hex file
+    --timeout=n      -t n        Search for bootload string for n seconds
+
+If both `--console` and `--flash` are specified, then the device will be reflashed first, then the console will connect.

 Preparing your user code for usage with the bootloader is very simple. All you
 need to do is set your linker to start the code section at 0x400. For an
 example of this see the `Makefile` file in the `example_payload` subdirectory.
