To create your first project, hover over "Projects" in the sidebar and click on the "+" icon.
This will open the "New Project" page so you can create your first project.
From here, all you need to do is name your project and either click on "Create" or press Enter on your keyboard and your project will be created.
Alternatively, you can click on "Start with a template" above the project name to start your project using a template (if you have one defined already).
Once your project has been created you can invite people, add a description and add tools to your project.
