 You can use any of the following options when running the emulator:
 
 - Mount a local folder to the container: Use this option to mount a folder in the host environment into the container. Mounting a host folder enables your queries to interact with local files, which is useful for [creating a database persistent between container runs](#create-a-database) and [ingesting data](#ingest-data).
 
-    For example, to mount the folder "D:\host\local" on the host to the folder "c:\kustodatadata" in the container, use the next command on Windows Server:

+

     ```

+
 - Run on a different port: The Kusto emulator exposes access to the Kusto Query Engine on port 8080; hence in other examples you mapped the host port 8080 to the emulator port 8080. You can use this option to map a different host to the engine.
 
     For example, to map port 9000 on the host to the engine, use the following command on Windows Server:
 
     ```powershell

 ## Create a database
 
 To store data and run queries, create a database or attach the emulator to an existing database.
 
-A database can be persisted in a container folder or on a [mounted folder](#run-emulator-options).  The former's lifetime is bound to the container, so restarting the container loses any changes.  Also, the container virtual storage is less efficient than native one.  Mounted folder enables you to keep the data between container runs.

Also, the container virtual storage is less efficient than native one. Mounted folder enables you to keep the data between container runs.
 
 In this example, we keep the data on the container.

+# [Linux container](#tab/linux-container)
 
 ```kusto
 .create database <YourDatabaseName> persist (
-  @"c:\kustodata\dbs\<YourDatabaseName>\md",
-  @"c:\kustodata\dbs\<YourDatabaseName>\data"
+  @"/kustodata/dbs/<YourDatabaseName>/md",
+  @"/kustodata/dbs/<YourDatabaseName>/data"
   )
 ```
 
-The equivalent command for a Linux container image is:
+# [Windows container](#tab/windowscontainer)
 
 ```kusto
 .create database <YourDatabaseName> persist (
-  @"/kustodata/dbs/<YourDatabaseName>/md",
-  @"/kustodata/dbs/<YourDatabaseName>/data"
+  @"c:\kustodata\dbs\<YourDatabaseName>\md",
+  @"c:\kustodata\dbs\<YourDatabaseName>\data"
   )
 ```
+---
 
 This command requires that the folders don't already exist, to prevent over-writing existing information. To attach to an existing database, use the following command instead, specifying the path that ends with `md`:
 
 ```kusto
 .attach database <YourDatabaseName> from @"<PathToMdFolder>"
 ```
 
-It's also possible to detach the database from the emulator, which will keep all the database metadata and data intact (so you could reattach to it in the future):
