 system from https://dl.altera.com/?edition=web Please make sure you download
 vesion 13.1 as newer versions don't support the Cyclone III FPGA anymore.

+Selecting "Start Compilation" from the "Processing" menu will create the led.rbf
 file. Putting this under the name "core.rbf" on sd card and booting the
 mist from that card should result in the FPGA led blinking once a second.

+Using signaltap
+---------------
 
+Signaltap is a very useful tool when developing cores. It allows you to observe
+signals directly on the running FPGA. 
+
+You need a cheap usb blaster cable to use this feature. Searching for "usb blaster"
+on ebay or amazon should give plenty of matching results.
+
+The blaster cable is connected to the PC via USB. For more information see the
+[Wiki](https://github.com/mist-devel/mist-board/wiki/UsingAByteBlaster). You also
+need to add a matching connector to your MIST board. Althoug the board is prepared
+for this connector you still need to get it soldered to the board.
