-				 "The GUI is still in the early stages of development, so we expect there to be a lot of bugs.\n \n"
+				 "To get starting using the GUI, drag a processor from the list "
+				 "on the left and drop it onto the signal chain. Each processor is "
+				 "classified as either a source, a filter, or a sink. "
+				 "Sources supply the data to each signal chain, filters process the "
+				 "data, and sinks use the data to control outputs. Data always flows "
+				 "from left to right.\n \n"
+				 "Every signal chain must have one and only one source, and no more "
+				 "than one sink. If a source is dropped in the middle of a signal chain, "
+				 "it will start its own chain. Likewise, if a sink is dropped in the middle "
+				 "of a chain, the processors to its right will form a new chain. Future "
+				 "versions of the software will support multiple sources and sinks through "
+				 "the use of splitters and mergers. The current GUI allows up to "
+				 "five unique signal chains to be constructed.\n \n"
+				 "Once the signal chain is in place, you can start and stop acquisition "
+				 "by pressing the ""play"" button at the top of the screen. Acquisition will "
+				 "only begin if all of the processors in the signal chain are enabled. Disabled "
+				 "processors appear gray. Processors may be disabled if they aren't connected to a "
+				 "source, or if they receive input from a processor to which they cannot connect." 
+				 "You'll have to fix these issues before you can acquire data.\n \n"
+				 "You can also start acquisition by pressing the record button, but it's "
+				 "not programmed to do anything just yet.\n \n"
+				 "The GUI is still being actively developed, so it lacks "
+				 "many crucial features and includes more than a few bugs. "
+				 "There's a lot we're still planning on adding, and we will "
+				 "be glad to have some help down the road. If you'd like to be "
+				 "added as a contributor, please get in touch with us at "
+				 "http://open-ephys.com/contact\n \n"
+				 "DISCLAIMER: This software should be used for demonstration and testing purposes only. "
+				 "It is not fit for conducting scientific experiments of any kind."
