+		<h1>Minesweeper</h1>
+
+		<p>
+			Minesweeper is a classic game about sweeping everything except
+			mines. Reveal all the non-mine tiles to win, but attempt to reveal a
+			mine and you won't be having such a good time. Revealed tiles will
+			have a number on them to tell you how many mines are directly
+			adjacent to them. Have fun, and watch out for the mines!
+		</p>
+
+		<br>
+
+		<p>
+			Flag tiles to mark them as mines. Chord numbered tiles to reveal all
+			adjacent non-flagged tiles if there are exactly that many flags
+			adjacent to the tile.
+		</p>
