Hi Keeper Eric, I'm not aware of a specific tutorial, but have you read through the wiki on Building Character Sheets ? Building sheets require at least a small amount of html and css knowledge and javascript depending on more advanced sheet features. Lot's of tutorials on the web for all three of those. I would recommend editing an existing sheet (copy the raw text for the html, css, and translation from the roll20 github repo ) that might be similar to Gangbusters and/or Top Secret (I still have that one in a box in the attic...). Paste the html, css, translation text into your ''custom" test game editor and play around with the code to get familiar with how roll20 sheets work. Test your changes by saving your edits and loading the test game in a new tab. Don't rely on the Preview tab in the editor since it is often known to be less than accurate. Later, after you get a little editing experience, you can make your own sheet since trying to mod someone else's sheet can have it's own pitfalls... Post back as you have questions. Lot's of helpful people here.
