+# Example Doodads
+
+This repository includes some example doodads for Sketchy Maze.
+You can learn from their scripts or use them as a base for your
+own custom doodads.
+
+All of these doodads are built from PNG images using the
+`doodad` program that comes with the game. Check your guidebook
+for information where you might find this program. The doodad
+files are constructed by the `doodad` tool so it should be
+somewhere on your `$PATH`. See the `build.sh` script in each
+example for the doodad commands used.
+
+* [**Playable Character**](character/): making your own character
+  with animations that follow your keypresses, like the
+  built-in creatures.
+* [**Warp Door**](warp-door/): create your own compatible Warp
+  Door that you can link to the built-in doors.
+
+To do:
+
+* **State Doodads**: create your own "blue" and "orange" boolean
+  state doodad that follows along with the rest.
+
+# See Also
+
+* The [User Guidebook](https://www.sketchymaze.com/guidebook/) of
+  Sketchy Maze.

+# Playable Character
+
+![Example Character](stand-right.png)
+
+This is an example how to create a custom playable character for your
+level. This will create a grayscale copy of the game's default player
+character.
+
+If you Link him to a Start Flag, you will play as him when the level
+starts and he faces the direction you're moving and animates and so
+on.
+
+If dropped in your level as an enemy character, his A.I. is to move
+right and left, turning around when it meets an obstacle. He is able
+to pick up keys, unlock doors, and activate buttons and switches. He does not travel through Warp Doors.

+# Warp Door (Grey)
+
+![Warp Door (Grey)](door-1.png)
+
+This example contains sprites and JavaScript to make your own
+Warp Door which is compatible with the built-in doors. This
+doodad will be a greyscale version of the built-in Warp Door.
+
+The door can be linked to other doors and the player can open
+and travel between them.
+
+**Note:** the title of your doodad must contain the text
+"Warp Door" for other doors to recognize your door.
