Is there a dummy field to provide additional instructions to the users on node add form? I'm building quite complex node form and I need to provide users with additional instructions how to fill the form. Are there any modules that would allow me to add sort of dummy fields with some HTML that would be displayed when user edits or creates new node? I don't want to save any data for these fields. I would like to be able to provide some HTML that will be displayed among other node form elements. Even plain text would do.
Try the Markup module:


  This module adds the ability for site admins to add "Markup" widgets to the form. These essentially let designers of cck content-types insert additional markup into the node/edit form to display to content-authors. This is the equivalent of adding additional elements to $form of the type '#markup'.
