 [id="how-it-works_{context}"]
 
-When a {prod-short} workspace starts, the `che-theia` container starts the telemetry plug-in, which is responsible for sending telemetry events to a backend. If the `$CHE_WORKSPACE_TELEMETRY_BACKEND_PORT` environment variable was set in the workspace Pod, the telemetry plug-in will send events to a backend listening at that port.
-
-If the {prod-short} workspace has a telemetry back-end container running, and it is listening on `$CHE_WORKSPACE_TELEMETRY_BACKEND_PORT`, it takes the events sent from the telemetry plug-in, turns them into the backend-specific representation of events, and sends them to the configured analytics backend (for example, Segment or Woopra).

-=== {devworkspace} telemetry
-
-Telemetry for {devworkspace}s works similarly to telemetry for {prod-short} workspaces, with the main differences being:
-
-. A {devworkspace} telemetry plug-in listens for events on `$DEVWORKSPACE_TELEMETRY_BACKEND_PORT` instead of `$CHE_WORKSPACE_TELEMETRY_BACKEND_PORT`.
-
-. The {devworkspace} telemetry plug-in requires version 0.0.34 or later of the link:https://github.com/che-incubator/che-workspace-telemetry-client/tree/master/backend-base[telemetry plug-in dependency].

 = The Woopra telemetry plug-in

+The link:https://github.com/che-incubator/devworkspace-telemetry-woopra-plugin[Woopra Telemetry Plugin] is a plug-in built to send telemetry from a {prod} installation to Segment and Woopra.
 This plug-in is used by link:https://workspaces.openshift.com[Eclipse Che hosted by Red Hat], but any {prod} deployment can take advantage of this plug-in.
 There are no dependencies other than a valid Woopra domain and Segment Write key.
-The link:https://raw.githubusercontent.com/che-incubator/che-workspace-telemetry-woopra-plugin/master/meta.yaml[plug-in's meta.yaml] file has 5 environment variables that can be passed to the plug-in:
+The devfile v2 for the plug-in, link:https://raw.githubusercontent.com/che-incubator/devworkspace-telemetry-woopra-plugin/main/plugin.yaml[plugin.yaml], has four environment variables that can be passed to the plug-in:
 
 - `WOOPRA_DOMAIN` - The Woopra domain to send events to.
 - `SEGMENT_WRITE_KEY` - The write key to send events to Segment and Woopra.
 - `WOOPRA_DOMAIN_ENDPOINT` - If you prefer not to pass in the Woopra domain directly, the plug-in will get it from a supplied HTTP endpoint that returns the Woopra Domain.
 - `SEGMENT_WRITE_KEY_ENDPOINT` - If you prefer not to pass in the Segment write key directly, the plug-in will get it from a supplied HTTP endpoint that returns the Segment write key.
 
-To enable the Woopra plug-in on the {prod} installation, deploy the `meta.yaml` file to an HTTP server with the environment variables set correctly. Then, edit the `CheCluster` Custom Resource, and set the `spec.server.customCheProperties.CHE_WORKSPACE_DEVFILE_DEFAULT__EDITOR_PLUGINS` field:
