So what is included in the brand guidelines?
A set of rules will list out the correct colour palettes specification, font choices and imagery styles that you use to communicate through, as well as the use of your logo in sizing and positioning. Other relative methods you use to create your distinctive brand, such as structural layout grids, spacing and typography detailing should be included with examples. A good set of guides will provide examples of both the correct and incorrect ways to use each element and include any secondary choices.
