There's multiple ways to create a task in Hello Ivy.

The two main ways to create a task are either via the "Today" page or the "Tasks" page in a project. When you create a task via the Today page you can decide for which project you want to create the task or maybe even for no project at all. This means you can also create personal tasks which will only ever show up in the Today overview.

You can also create tasks on the task board (or list) in a project. To create a task you simply click "+ new task" and fill in a title. There's a lot more you fill in (eg. labels, dates, urgency, etc.) but giving your task a title is the minimum in order to create the task.
