Making my own Template
 

Are there any tutorials out there for making custom content for pathfinder? I've been trying to make a template of my own (Darksign, from the Dark Souls homebrew game setting I'm working on as a hobby) and I have no idea how to do more than open the editor.

Any help would be appreciated. Thanks!

There are a few tutorials out there on YouTube you could work with. Also, you could learn a few things about the editor from the help files that come packaged with it. Just open the editor and use the Help menu to access "Help on using the editor". This provides a few basic tutorials to get you started. I'd recommend at least reading through them once or twice before adding something. The reference information contained there is also useful for building custom content.
