+# Check manifest path
+
+Check `manifest_path` value in Kubernetes deployment manifest annotations, in case the value found is a path that doesn't exist it will break the job.
+
+This action will assume that the deployment manifest will use the word `manifest` in their paths.
+
+## Usage
+
+```yaml
+- name: Check manifest paths in deployment files
+  uses: resuelve/check-manifest-path-action@master
+```
+
+Enjoy 🎉
