Contributor guide

Research direction
Find all React components that use static getDerivedStateFromProps. For each component, determine if it can be converted to a PureComponent or if memoization with memoize one is appropriate. Follow the guidance in the linked blog post to replace the lifecycle method. Run the existing tests to ensure no regression.
