+Metadata Extraction
+*******************
+
+If `datalad-metalad`_ extension is installed, `datalad-container` can
+extract metadata from singularity containers images.
+
+(It is recommended to use a tool like `jq` if you would like to read the
+output yourself.)
+
+For example:
+
+``datalad meta-extract -d . metalad_container images/bids/bids-pymvpa--1.0.2.sing  | jq``
