+"""Levels are saved as user levels, and stored in $XDG_DATA_HOME/.mamba/user_levels (i.e.
+~/.local/share/.mamba/user_levels) or $APPDATA/.mamba/user_levels on Windows.
+
+A new level can be created from one of the existing templates using "New". Level properties, such as the
+name, filename and background music track can be changed using the "Edit Level Metadata" button.
+
+The level editor has 3 modes: placing tiles, placing things and editing sprites.
+
+Tiles are level geography, such as floors, walls and so forth.  Things are items that the snake can eat, such as rats.
+Sprites are special elements with more complex items which require extra configuration information, such as tunnels.
+
+To place tiles and things, select the desired element and click on the map to place the tile or thing.
+Deleting anything replaces the space with a floor tile (Right click also deletes). The selection of
+tiles can be scrolled using the arrow buttons.
+
+Sprites can be placed as well. Sprites require parameters. Each sprite needs a unique id tag, which can
+be any string without spaces, and then additional parameters that depend on the type of sprite, usually
+the id of another sprite. Sprites can be added, edited and deleted.  Look at existing maps to see how
+the parameters can be used.
+
+Levels can be saved, and uploaded to be shared with other people. Shared levels
+only become available after the levels have been curated by the Mamba team.""")
