+Sync and cache test resources. This action will sync test resources from
+different sources (e.g. S3) and cache them for later use. The cache key
+is based on the hash of the test resources. For this action to work, the
+Viash project config should contain a list of test resources to sync.
+
+Supported storage types:
+
+- `s3`: Syncs resources from an S3 bucket.
+- Create a GitHub issue if you need support for other storage types.
+
+Example:
+
+``` yaml
+info:
+  test_resources:
+    - type: s3
+      path: s3://my-bucket/my-folder
+      dest: my-folder
+```
+
+### Inputs
+
+- `project_config`: - *optional*. Path to the project configuration
+  file.
+- `cache_key_prefix`: - *optional*. A prefix for the cache hash key.
+  Prefix is also used for restoring stale cache if no cache hit occurred
+  for key.
+
+### Outputs
+
+- `cache_key`: Caching key.
+- `dest_paths`: Paths to the synced resources.
