Vide - help me understand the definition?

From online dictionary (link below):

vide - "to see, used especially to refer a reader to parts of a text. Often used in the phrases vide ante (see before), vide infra (see below), vide post (see after), vide supra (see above), vide ut supra (see as above), etc "

Hope that helps!

Vide means to see. It is a word used to direct the reader to look into another item.
