+The Tile Interface
+==================
+
+Module name
+-----------
+
+Your tile will have a module name such as ``weatbag.tiles.s3e11``, which
+determines its position on the grid. The co-ordinates use compass directions: n/s
+followed by e/w. If one co-ordinate is 0, it should be left out. So the tiles
+around the centre are named:
+
++------+------+-------+------+------+
+| n2w2 | n2w1 | n2    | n2e1 | n2e2 |
++------+------+-------+------+------+
+| n1w2 | n1w1 | n1    | n1e1 | n1e2 |
++------+------+-------+------+------+
+| w2   | w1   | centre| e1   | e2   |
++------+------+-------+------+------+
+| s1w2 | s1w1 | s1    | s1e1 | s1e2 |
++------+------+-------+------+------+
+| s2w2 | s2w1 | s2    | s2e1 | s2e2 |
++------+------+-------+------+------+
+
+The Tile class
+--------------
+
+Your module should define a class called ``Tile``, with the following interface:
+
+.. class:: Tile()
+
+   .. method:: describe()
+   
+      Describe the scene and anything in it. This is called when the player
+      enters the tile, and again if they look around.
+
+   .. method:: action(player, do)
+   
+      Called when the player does something inside the tile. You need to
+      interpret the action and carry it out.
+      
+      :param player: the active :class:`~weatbag.Player` instance
+      :param action: list of strings - the player's input, split up into words,
+                     lowercase and with prepositions removed
+
+   .. method:: leave(player, direction)
+   
+      *Optional.* Called when the player tries to leave the square. To let them
+      leave, return `True`, or to prevent them, print an explanation and return
+      `False`. If the method isn't found, the player can always leave.
+      
+      :param player: the active :class:`~weatbag.Player` instance
+      :param direction: the direction the player is trying to leave, as a single
+                        lowercase character, n/e/s/w
+      explanation
