+## Connector to Azure Cosmos DB
+
+From within the Confluent Hub client, install the Cosmos DB Connector as recommended in the [Confluent Hub listing](https://www.confluent.io/hub/microsoftcorporation/kafka-connect-cosmos). 
+
+To install the connector manually, first download an uber JAR from the [Cosmos DB Releases page](https://github.com/microsoft/kafka-connect-cosmosdb/releases). Alternatively, you can [build your own uber JAR directly from the source code](https://github.com/microsoft/kafka-connect-cosmosdb/blob/dev/doc/README_Sink.md#install-sink-connector). Complete the installation by following the guidance described in the Confluent documentation for [installing connectors manually](https://docs.confluent.io/home/connect/install.html#install-connector-manually).
