         <p>This is a simple implementation of the classic board game,

+        <h2>Castling</h2>
+        <p>Castling is a special move that allows a king and a rook to move at
+        the same time, under certain circumstances:</p>
+        <ul>
+          <li>The king cannot be in check</li>
+          <li>The space the king skips over cannot be in check</li>
+          <li>The spaces between the king and the rook must be empty</li>
+          <li>Neither the king nor the rook have already moved this game</li>
+        </ul>
+        <p>If these conditions are met, the king can move 2 spaces toward the
+        rook, and the rook moves into the space the king skipped over.</p>
+
+        <h2><em>En Passant</em></h2>
+
+        <p>Most people know that a pawn can jump two spaces the first time
+        it moves. <em>En passant</em> (French for "in passing") is a rare move
+        that can counter such a double-jump.</p>
+
+        <p>For example, say a white pawn double-jumps, and lands side-by-side
+        with a black pawn. That black pawn can then move into the space that
+        was jumped over (right behind the white pawn), and capture its
+        enemy!</p>
+
+        <p>It's not useful every game, but is very powerful in the right
+        situation!</p>
