+        Explicit listing of page references to include.
+
+        These should point at an existing documentation nested under `crim-ca` organization,
+        and published using the `gh-pages` branch of the corresponding repository.
+
+        Alternatively, it can be used to refer to an external documentation to provide a shortcut.

+        GeoImageNet is a collaborative research and annotation platform for researchers from different backgrounds
+        who wish to develop innovative algorithms for the exploitation of very high resolution (VHR) satellite images
+        for various applications.

+        Weaver is an OGC-API flavored <i>Execution Management Service</i>&nbsp(EMS) that allows the execution of
+        workflows chaining various applications and <i>Web Processing Services</i>&nbsp(WPS) inputs and outputs.
+        Remote execution is deferred by the EMS to one or
+        many <i>Application, Deployment and Execution Service</i>&nbsp(ADES) or remote service providers,
+        and employs <i><a href="https://www.commonwl.org/">Common Workflow Language</a></i>&nbsp(CWL) configurations
+        to define an <i><a href="https://github.com/opengeospatial/ogcapi-processes/blob/master/openapi/schemas/processes-dru/ogcapppkg.yaml">OGC Application Package</a></i>
+        deployed for each process.
