No documentation with texture icon paths

The documentation with texture icons is very vague, there's no mention of which directory it's supposed to read so it's practically impossible to guess where the texture can be accessed.

Ok I think I figured this out, directory starts out from minecraft, so If I wanted to display a bamboo texture I would have to write something like this {icon:textures/item/bamboo}. Had a hard time figuring it out since it doesn't use quotation marks and doesn't require you to specify the file type.
