+# Import Kubernetes Resources from YAML
+
+!!! info "Work in progress"
+
+    This guide is under construction and will be updated soon.
+
+The `cue` CLI can import Kubernetes objects from YAML files and convert them to CUE.
+
+Assuming you have a YAML file named `manifests.yaml` with one or more Kubernetes objects,
+run the following command in the module's root directory:
+
+```shell
+cue import /path/to/manifests.yaml \
+  -o -f templates/manifests.cue -p templates \
+  -l 'strings.ToLower(kind)' -l 'metadata.name'
+```
+
+The generated CUE definitions will be written to `templates/manifests.cue`, from where you can
+modify them to fit with the Timoni's template model.
