+You can also change the table name by setting the corresponding environment variables:
 ```ruby
 DATA_MIGRATIONS_TABLE_NAME=new_table_name
-DATA_MIGRATIONS_INDEX_NAME=new_index_name

 This can enable more complex use cases, such as data migrations intended for different contexts,
 or running multiple sets of data migrations in a specific order. It may also avoid conflict with existing path or table names
