* `path` - A list of files, directories, and wildcard patterns to cache and restore. See [`@actions/glob`](https://github.com/actions/toolkit/tree/main/packages/glob) for supported patterns.

* `restore-keys` - An ordered list of prefix-matched keys to use for restoring stale cache if no cache hit occurred for key.

It is very important to use the same `key` and `path` that were used by either `actions/cache` or `actions/cache/save` while saving the cache.

## Tips
### Reusing primary key and restored key in the save action
#### Reusing primary key and restored key in the save action
Usually you may want to use same `key` in both actions/cache/restore` and `actions/cache/save` action. To achieve this, use `outputs` from the restore action to reuse the same primary key (or the key of the cache that was restored).
### Using restore action outputs to make save action behave just like the cache action
#### Using restore action outputs to make save action behave just like the cache action
The outputs `cache-primary-key` and `cache-matched-key` can be used to check if the restored cache is same as the given primary key. Alternatively, the `cache-hit` output can also be used to check if the restored was a complete match or a partially restored cache.
#### Ensuring proper restores and save happen across the actions
It is very important to use the same `key` and `path` that were used by either `actions/cache` or `actions/cache/save` while saving the cache.
