Using Components | Lightning Components Developer Guide

Use Lightning Components in Lightning Experience and Salesforce1
Customize and extend Lightning Experience and Salesforce1 with Lightning components. Launch components from tabs, apps, and actions.

Get Your Lightning Components Ready to Use on Lightning Pages
Custom Lightning components don’t work on Lightning pages or in the Lightning App Builder right out of the box. To use a custom component in either of these places, you must configure the component and its component bundle so that they’re compatible.

Use Lightning Components in Community Builder
To use a custom Lightning component in Community Builder, you must configure the component and its component bundle so that they’re compatible.

Add Components to Apps
When you’re ready to add components to your app, you should first look at the out-of-the-box components that come with the framework. You can also leverage these components by extending them or using composition to add them to custom components that you’re building.

Integrate Your Custom Apps into the Chatter Publisher (Pilot)
Use the Chatter Rich Publisher Apps API to integrate your custom apps into the Chatter publisher. Rich Publisher Apps enables developers to attach any custom payload to a feed item. Rich Publisher Apps uses lightning components for composition and rendering. We provide two lightning interfaces and a lightning event to assist with integration.

Use Lightning Components in Visualforce Pages
Add Lightning components to your Visualforce pages to combine features you’ve built using both solutions. Implement new functionality using Lightning components and then use it with existing Visualforce pages.

Add Lightning Components to Any App with Lightning Out (Beta)
Use Lightning Out to run Lightning components apps outside of Salesforce servers. Whether it’s a Node.js app running on Heroku, a department server inside the firewall, or even SharePoint, build your custom app with Force.com and run it wherever your users are.
