+## Notes for Large OpenAPI documents
+If the OpenAPI document is large, imports in petstore_api.apis and petstore_api.models may fail with a
+RecursionError indicating the maximum recursion limit has been exceeded. In that case, there are a couple of solutions:
+
+Solution 1:
+Use specific imports for apis and models like:
+- `from petstore_api.api.default_api import DefaultApi`
+- `from petstore_api.model.pet import Pet`
+
+Solution 1:
+Before importing the package, adjust the maximum recursion limit as shown below:
+```
+import sys
+sys.setrecursionlimit(1500)
+import petstore_api
+from petstore_api.apis import *
+from petstore_api.models import *
+```
