+
+### Notes
+Adding packages to a running Spark pool might take time as the cluster may need to be reprovisioned.
+
+Azure Synapse allows storing JAR files in an Azure Storage Account, which can be linked to your Spark pool.

+   - Navigate to your Synapse Studio.
+   - Go to the **Manage** tab and select **Apache Spark pools**.
