Where do I begin if I want to start a project?

Only authenticated users can create content and therefore projects. So first you need to log in or create a new account.

Once you login, look for the "Create content" link. It should be found in the navigation menu, on the upper left corner under the main menu.

Expand it and, depending on your permissions, you will see what type of content you can create.

For this particular case choose "Project".
