 When starting the MS SQL Server container, you can pass options in a variadic way to configure it.
 
+#### Scripts
+
+If you need to execute SQL scripts when the container starts, you can use `mssql.WithScripts` with one or more script file paths. The scripts will be executed in order after the container is ready.
+
+```golang
+mssql.WithScripts("/path/to/schema.sql", "/path/to/data.sql")
+```
+
+This will:
+1. Copy each script into the container
+2. Execute them using `sqlcmd` after the container is ready
+
+#### SQL Command Path
+
+The `mssql.GetSQLCmdPath` helper function returns the appropriate path to the `sqlcmd` executable based on the MS SQL Server image being used. This is used internally by the `WithScripts` option but can also be used directly if needed.
+
+```golang
+path := mssql.GetSQLCmdPath("mcr.microsoft.com/mssql/server:2022-latest")
+```
+
 #### Image
 
 If you need to set a different MS SQL Server Docker image, you can set a valid Docker image as the second argument in the `Run` function.
