+If Weave Net is installed via `docker plugin install`, download the
+`weave` script to run `weave status`, `weave ps` or `weave report` as
+above.  Install Weave Net by following the [install
+instructions](/site/install/installing-weave.md).
+
+Docker "v2" plugins do run as containers, but at a lower level within
+the Docker environment.  Because of this, you cannot view them with
+`docker ps`, `docker inspect`, etc.
+
+Do not run `weave launch`, `weave stop` or similar commands when using
+this plugin; use the `docker plugin` commands instead.  You can run
+`weave reset`, but only after disabling the plugin via `docker plugin disable`.
+
+Diagnostic logs from the plugin go to the same place as the Docker
+daemon, which will depend on your Linux install. For example, if it
+uses `systemd`, then do this to view the Docker and plugin logs:
+
+    sudo journalctl -u docker
