You can add a new project from almost any screen in ProWorkflow. Click on the '+ Add' button appearing just below your nav bar, followed by the Project option.
The first choice you'll need to make when creating a new project is whether you would like to use a template, or start from scratch. This will be the difference between starting with some templated information that may have been drawn from earlier projects, and a totally fresh slate that you'll be entering new details into.
From there, you will be given some basic choices surrounding things like the title, current work stage and start date. Once these details have been entered, click the 'Create' button along the bottom right.
At this time, you'll be taken to your new projects' project details page, and you can begin adding tasks etc.
