+## Multiple packages
+If you have have a mono-repository setup you may want to split the output of queries and models. You can achieve this by using the `output_models_file_name`
+and `output_querier_file` fields. If `output_models_file_name` is set to `null` for it will not output the `models.py` file. Setting `output_querier_file` to false will prevent outputting any query files. Combining these you can set one codegen to only output models while the other codegen outputs only queries. Make sure the `package` configuration is set equally so the query files import correctly the models.
+
+SQLC needs at least one query, so you may need to add a unused query like the following in your schema and reuse the `schema` as `queries`.
+```sql
+-- name: Skip :one
+SELECT 1;
+```
