Template:Location infobox/doc

Color is out of the same options of M1, EB, M3, etc. as in other templates.

Captionyn and caption are optional. If you want a caption for the image, then put in "captionyn=yes", along with the desired caption in the caption field.

Region is similarly optional by "optionyn=yes/no", and when used, it is automatically in brackets. Connected, however, is not; this will need brackets and line breaks between area names.
