A knowledge base is essential for customers to help themselves and for businesses to support their teams, create better products, and improve customer experiences. To set up an effective knowledge base, one should choose what to document, creating easy-to-understand content with good formatting and simple language, finding a suitable host, organizing the documentation into categories, making it easy to find, and keeping it improving through feedback and integration with unified communications. By following these steps, businesses can create a dependable help center that empowers customers to use their products independently while also supporting their teams and business operations.
