 ## Quick start
 
 To use Polly, you must provide a callback and execute it using [**resilience pipeline**](docs/resilience-pipelines.md). A resilience pipeline is a combination of one or more [**resilience strategies**](docs/resilience-strategies.md) such as retry, timeout, and rate limiter. Polly uses **builders** to integrate these strategies into a pipeline.
