+### Resources
+
+Conditions can declare input [`PipelineResources`](resources.md)  via the `resources` field to 
+provide the Condition container step with data or context that is needed to perform the check.
+
+Input resources, like source code (git), are dumped at path
+`/workspace/resource_name` within a mounted
+[volume](https://kubernetes.io/docs/concepts/storage/volumes/). The condition container can use the `path`
+[template](./tasks.md#Templating) key to refer to the local path to the mounted resource.

+```yaml
