There are two places to add a new project:
To add a new project to the dash, click the + ADD PROJECT button in the upper bar or on the dash (if you haven't got any projects yet).
A new project page will open in the same tab so that you can add all the necessary project details right away. You can do it now, later, or leave all fields empty.
To add a new project to a specific folder, make sure you are in the right folder first. You can find the folder name right under the main menu bar and on the left pane.
To create a new project from a folder page, click on the ADD PROJECT button on the main menu bar.
⚠️ Note that users on the free plan can have only 1 project.
