 ## Sprite Sources
 
-Given a directory with SVG images, Martin will generate a sprite -- a JSON index and a PNG image, for both low and high
-resolution displays. The SVG filenames without extension will be used as the sprite image IDs. The images are searched
-recursively in the given directory, so subdirectory names will be used as prefixes for the image IDs,
-e.g. `icons/bicycle.svg` will be available as `icons/bicycle` sprite image. The sprite generation is not yet cached, and
