+# Limitations
+
+gui resources files are populated under `~/.cache/mycrot/ovos-gui` by skills and other OVOS components and are expectd to be accessible by GUI client applications
+
+This means GUI clients are expected to be running under the same machine or implement their own access to the resource files (resolving page names to uris is the client app responsibility)
+
+> TODO: new repository with the removed GUI file server, serve files from `~/.cache/mycrot/ovos-gui` to be handled by client apps
+
+In case of containers a shared volume should be mounted between ovos-gui, skills and gui client apps
