There's nothing simpler than creating your brand guide with FreeLogoDesign.

When you choose this option, you will be redirected to a page with all the information of your logo (colors, fonts, name) as shown in the image below.

You can, if you wish, exchange the ranking of the different colors and fonts.

You will then find that all you have to do is select the language you want and click on download.  A ZIP file will then be downloaded, and you will then find a PDF format.
