+Connector plugins should preferably be placed into `/app/libs`, thus requiring an environment variable of `CONNECT_PLUGIN_PATH="/app/libs"`.

 To re-iterate, `confluent-hub` is **not** part of the base image versions; they **only include** Connector classes provided by Apache Kafka. 
 These are limited to File Sink/Source and MirrorSource Connector (MirrorMaker 2.0). In general, you'll probably want to add your own Connectors, as above, rather than use this image by itself.
 
+As of 3.6.0 release, the `confluent-hub` tags include `unzip` shell command for extracting other third-party connectors.

 For a full example of adding plugins, and using the [Confluent Schema Registry](https://docs.confluent.io/platform/current/schema-registry/index.html), 
 please [refer to the `schema-registry` branch](https://github.com/OneCricketeer/apache-kafka-connect-docker/blob/schema-registry/Dockerfile.schema-registry).
