Why do you want to do that? - I had the problem of adding verbose instructions and I just add it as a page in a blog on Wordpress (which is free) with a weblink. You can make it look however you like on Wordpress.
Adding a font just needs you to find its position in your operating system. You click on Font in resource. Click here to add a new font and then click the custom button to find the font- if you use a Windows its in C:\WINDOWS\Fonts.
Note weblinks only work once the game is published.
