+	<h1>Depths of the Mind</h1>
+
+	<p>
+		The mind is an intricate thing, with many tiny components working together
+		in perfect harmony... Until something came in and messed everything up!
+	</p>
+
+	<p>
+		If you want to set all the pieces of the mind right, you'll need to know how
+		it works!
+	</p>

+
+	<p>
+		The structure of the brain consists of black blocks filling a white void.
+	</p>
+
+	<img src=
+#include "../build/tutorial_red_yellow.png.b64"
+			>
+
+	<p>
+		Black blocks will turn red when clicked (if you have red in your inventory on the left).
+		While the brain is running, black blocks next to red blocks will turn red!
+		Red blocks will eventually tire to yellow, and then back to black. They don't stay red very long!
+		This is what allows the brain to send signals along a series of black blocks.
+		Yellow blocks can be placed with a right click on a black block (if you have one in your inventory)
+	</p>
+
+	<img src=
+#include "../build/tutorial_direction_red.png.b64"
+			 >
+
+	<p>
+		Sometimes, only one side of a block turns red.
+		When this happens, it will try to move in that direction (and leave a yellow behind it)
+		but if it cannot it will turn clockwise and try again.
+	</p>

+
+	<p>
+		Blue blocks need to be moved around to keep things running smoothly!
+		When a blue block is touched by a single red block, it will start rolling
+		away from it.
+		Each level has a goal in faint red which needs at least one blue block to be delivered to it.
+		Some levels will also have faint blue areas that create new blue blocks for you!
+	</p>
+
+		<img src=
+#include "../build/tutorial_blue_clone.png.b64"
+				 >
+
+	<p>
+		Finally, if a blue block touches a red block <em>while in motion</em> it will be cloned!
+		One will be left behind and the other will continue.
