To create a project just press the plus button as indicated in picture 1. On older devices the plus button will not be shown and you have to press the menu button of the device to open the options menu. The project will be created and you are asked to fill in the basic project properties a shown in picture 2. This data can always be changed later. Leave the project properties by pressing the device back button to start creating tasks. If you did not create a calendar you will be asked to create one. All following tutorials use a "Standard Calendar".
