Now that we have your site looking pretty and have some users set up, let's work through some of the basics of JIRA.
Wait! I don't know what JIRA is...
Create a project

A JIRA project is a collection of issues. Your team could use a JIRA project to coordinate the development of a product, track a project, manage a help desk, and more, depending on your requirements.
In this step, you will be creating a project for your team to use. You should still be logged in to JIRA as an administrator, from the previous stage. If not, log in under that administrator account.
- Choose Projects > Create Project and choose JIRA Classic.
- Enter JIRA Junior as the project name. Leave the project key set to its default value of JJ.
- Choose Submit to create your new project.
The project for "JIRA Junior" will be created and you will be shown the project summary page.
