" summary

Explains a concrete rollout workflow: add a flag in a config, wrap new behavior in an if statement (example name: Facebook audience revamp), ramp from 0–100% and monitor logs with kibana and gore fana, revert to 0% if errors spike. Uses a dog-borrowing app as a toy scenario and cites MailChimp metrics: 120 engineers seeing about 50 deployments a day after adopting flags. Emphasizes cleaning up flags to avoid technical debt.
