In your instruction on how to add custom form fields, the first step is to use the appropriate Give hook. Where can I add this give hook? Is it that I can access this by going to Plugins>Installed plugins>Give edit?
Sorry for asking a silly question, but for a non-developer, I don't know what "myprefix" represents or means in the first piece of code. Can you tell me what it means and how I can change this text to be customized to my site?
