Summary: TLDR even more docs changes So I created a More Resources doc that aggregates the high-quality-but-off-site stuff. Let's try to put more outlinks there. Also I removed the stuff on Support that was not support, and some misc changes to clean stuff up.

Components are the building blocks for a React Native application. A React Native user interface (UI) is specified by declaring components, often nested. Those components are then mapped to the native UI on the targeted platform.
####Props####
#####this.props#####
Components can be configured by passing properties props to the constructor. You can access props from your component's methods by accessing this.props. You should not alter your props within component methods.
####State####
#####this.state#####
Components maintain their state using the state object. You can access your component state via this.state. Each component should manage its own state. Parent components should not manage children state and children components should not manage parent component state.
#####this.setState({key: value, ...})#####
To update or change the state of your component passing a new object representing your newly desired state to this.setState(obj). The specificed keys will be merged into this.state. Any existing keys will be overridden by new values.
Core Components.
React Native has a number of core components that are commonly used in applications, either on their own or combined to build new components.
