At times, your process may contain some complicated step dependencies, or the steps themselves may be quite difficult to understand. In such cases, it would be convenient for yourself as well as other designers to add notes to certain parts of a process to write in personal comments that would be beneficial to users of the process.
Creating a step note
You can create/edit a step note by right-clicking the relevant step and selecting "Edit step notes".
You will then be presented with a pop-up window where you can add your own comments/notes.
You are also able to attach images or insert tables.
