+**What it does**
+
+The tool extracts visualisation from QIIME visualisation artifact datasets (qzv).
+
+QIIME visualisation artifact files are zip files that contain visualisations of the data
+which is extracted by this tool.
+
+Note that Galaxy contains a Display application that uses
+https://view.qiime2.org/ to show this data. For non-public Galaxy instances this
+does not work.
