To create a project, you need to go to the "Projects section" from the left sidebar.
Now, click on "+ Create Project" in the top right corner.

Now, give the name of the project. You may add other data as well, but those are totally optional.
Next, click on the Save button.

For members to track time, you need to assign them a project.
Scroll to the "Add People & Permissions" section and click on the Plus "+" icon to add members. You can assign a project based on a Team or an individual team member.

After adding members to the project, click on Save & Proceed below.
Now, employees can select that project from the desktop app for tracking time in.
