The brand book can be described as your brand’s user manual. It is a key tool and lets everyone know in detail how to use your brand image, on any support, both online and offline. The brand book is the keystone of a branding strategy. It contains all the elements that make up your brand, from its founding principles (mission, vision, values…) to its visual identity (logo, colors, visuals..). Thus, it serves as the document of reference for everything related to the use of your brand.
