   The Services Catalog page opens:

3. Click the Project field and select the Project that contains the Hello World of Services! pipeline and task.
4. For the Service name, enter Hello World.
5. For the URL slug, enter hello-world.

7. For Tags, enter service-tag and press Enter.
8. Click in the Servers field and select a Snaplex.
9. In the Description field, enter: This is the Service description. This description displays when you publish the Service and labeling the example in this way helps you identify where each description displays.
