### Using with GitHub Actions
This example shows how to use requests-cache with [GitHub Actions](https://docs.github.com/en/actions).
Key points:
* Create the cache file within the CI project directory
* You can use [actions/cache](https://github.com/actions/cache) to persist the cache file across
  workflow runs
    * You can use a constant cache key within this action to let requests-cache handle expiration
