Using Components | Lightning Components Developer Guide

Adding 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.

Add Lightning Components to Salesforce1
Make your Lightning components available for Salesforce1 users.

Add Lightning Components to Lightning Experience
Make your Lightning components available for Lightning Experience users.

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.

Configure Components for Communities
Make your custom Lightning components available for drag and drop in the Community Builder.

Configure Components for Lightning Pages and the Lightning App Builder
There are three steps you must take before you can use your custom Lightning components in either Lightning Pages or the Lightning App Builder.
