This guide has a lot of helpful coding templates for various features. The right column is HTML code templates you can copy into the Code View of your profile and then edit with your own text. When I use code templates like that, I often find it easiest to paste it in, save the bio, and then go back and edit the template text in regular view rather than having to do all the editing in code view, but sometimes it's easier to edit the code directly as you become familiar with it.
Some of the guide is directly copy-pastable, but sometimes formatting can get weird on Lorwolf when copy-pasting. If you have issues when copy-pasting, check the html in the code view to see if it added something weird.
And if you give it a go and get an idea of what you're looking for, I'm happy to help if you have specific questions or goals!
