* `key` - An explicit key for restoring and saving the cache

`cache-hit` returns false in this case.

* `SEGMENT_DOWNLOAD_TIMEOUT_MINS` - Segment download timeout (in minutes, default `60`) to abort download of the segment if not completed in the defined number of minutes. [Read more](#cache-segment-restore-timeout)

## Skipping steps based on cache-hit
Using the `cache-hit` output, subsequent steps (such as install or build) can be skipped when a cache hit occurs on the key.
Using the `cache-hit` output, subsequent steps (such as install or build) can be skipped when a cache hit occurs on the key. It is recommended to install the missing/updated dependencies in case of a partial key match when the key is dependent on the `hash` of the package file.
Example:
