Optional: Install the Expense Tracker App

If you want to skip over the quick start tutorial, you can install the Expense Tracker app as an unmanaged package. Make sure that you have a custom domain enabled in your organization.
A package is a bundle of components that you can install in your org. This packaged app is useful if you want to learn about the Lightning app without going through the quick start tutorial. If you’re new to Lightning components, we recommend that you go through the quick start tutorial. This package can be installed in an org without a namespace prefix. If your org has a registered namespace, follow the inline comments in the code to customize the app with your namespace.

Make sure that you have a custom domain enabled. Install the package in an org that doesn’t have any of the objects with the same API name as the quick start objects.

Note

  1. Click the installation URL link: https://login.salesforce.com/packaging/installPackage.apexp?p0=04t1a000000EbZp

See Add Lightning Components as Custom Tabs in Salesforce1 for more information.

The Lightning component tab isn’t available if you don’t have a custom domain enabled in your org. Verify that you have a custom domain and that the Expenses tab is available in the Lightning Components Tabs section of the Tabs page.
