Provide guidelines for using brand assets in social media and marketing materials

## Description
While the Base Brand Kit includes logos and icons, there is no clear explanation on how to properly use these assets for social media profiles, ads, and other marketing materials.

## Problem Description
Designers and developers may not be sure about the appropriate size, format, or layout when applying logos and icons to social media or promotional content, leading to inconsistent branding across platforms.

## Proposed Solution
Add a section to the documentation that offers straightforward instructions on how to use the brand kit assets for social media profiles, advertisements, and other marketing materials.
