Try It Out: Create a Lightning Page Tab

In Setup, enter Tabs in the Quick Find box, then select Tabs.
Click New in the Lightning Page Tabs related list.
Select our Deliveries Lightning Page for the tab.
Enter My Deliveries as the label.
This text becomes the name for the Lightning Page in the Salesforce1 navigation menu, and it also displays in the Lightning Page header along with its corresponding icon.
Click the Tab Style lookup icon to display the Tab Style Selector.
Click the Globe style.
The icon on the style that you select is the icon that displays to the left of the Lightning Page label in the Salesforce1 navigation menu.
Click Next.
Leave the tab applied to all profiles.

In Salesforce Classic, the Default On and Default Off options for Lightning Page tabs don’t work the same way as for other custom tabs. The Lightning Page menu item appears for the selected profiles in Salesforce1 whether you choose Default On or Default Off. Select the Tab Hidden option to hide the Lightning Page menu item for the selected profiles.
Note
Click Save.

Example

All right! The tab is created. Now we can make our Lightning Page available in Salesforce1.
