The document discusses how feature toggles can help address "merge hells" that can occur with continuous integration. Feature toggles allow incomplete features to be deployed without being released, avoiding the need to rollback deployments. They enable options like A/B testing, canary releasing, and managing experimental and operations toggles. To manage feature toggles, teams should follow mainline development practices, use feature toggle tools, set expiry dates for toggles, and consider toggles as a first step towards continuous delivery.
