It's important to keep all your marketing on-brand! So when you are working with creative partners (think: graphic designers, website designers, copywriters, etc.), you can send your brand guide to help them with creative direction.
Here's how to create a good one:
Upload or create a mood board in the first section of your brand guide. This helps people understand the overall vibe of your brand
Use AI to create your brand voice in the next section. This is will help anyone writing copy for you understand how it should sound, and it also will help the AI copywriter in Enji draft things that sound like you too
Under that is your brand's color palette. The best practice is to create this in your brand asset library first because (if you do) it'll automatically show up here as well
Same thing with your logo files and fonts—do that in the brand asset library to avoid having to upload things multiple times
