+## Using the plugin in local development environment
+
+You can use this plugin with Azure Storage Emulator in a local development environment by setting the development flag in the configuration file:
+```
+akka.persistence.journal.azure-table.development = on
+akka.persistence.snapshot-store.azure-blob-store.development = on
+```
+
+you do **not** need to provide a connection string for this to work, it is handled automatically by the Microsoft Azure SDK.
