Creating a project
Make a project any time you realize you have something you need to do which requires more than one step.
To create a project:
Make sure you are in planning mode; an easy way to get there is by clicking the Projects button in the toolbar:
Click the plus button at the bottom of the sidebar.
Type a title for your new project.
Regardless of which view mode you are in, you can also create a new project by clicking the Add Project button in the toolbar, choosing Add Project from the File menu, or typing Command-Shift-N. OmniFocus switches to planning mode automatically.
