+* ### How do I run a script after installation?
+
+  To run your own script after installation, you can create a file called `install.bat` and place it in a folder together with other files it needs (programs to install for example). Then bind it in your compose file like this:
+
+  ```yaml
+  volumes:
+    -  /home/user/example:/storage/oem

+
+  The example path `/home/user/example` will be copied to `C:\OEM` during installation and the containing `install.bat` will be executed.
+
 * ### How do I assign an individual IP address to the container?
 
   By default, the container uses bridge networking, which shares the IP address with the host.
