Hi Sonal,

I am not getting option to enable lighting components in my ORG. Can you please guide me navigation steps to reach at the page from where I can enable lighting components.

Your custom Lightning components don’t automatically work in the Lightning App Builder. To make a custom component usable in Lightning Pages and in the Lightning App Builder, you need to configure the component and its component bundle. For details, see “Configure Components for Lightning Pages and the Lightning App Builder” in the LightningComponents Developer’s Guide.

I am unable to access the article mentioned above. “Configure Components for Lightning Pages and the Lightning App Builder” https://developer.salesforce.com/docs/atlas.en-us.198.0.lightning.meta/lightning/ what this moved to a different location?  Looking for help with adding the custom components under the "Custom - Manged" drop down.
