If you are an account admin, account owner, or a project creator - you have the ability to create or delete projects. To create a new project, just go into your projects page (folder icon on the left side panel), and you should see the following screen:
Simply click on the large button to "Create a new Project." Once you click on this, you will be prompted to enter a project name, and what account this project should be in (i.e. if you have multiple accounts). We highly recommend clicking on the "(+) More options and processing defaults" to set up your project preferences. Once data is uploaded, most of these options will be permanent, such as the time zone or rendering.
