@@ -84,7 +84,12 @@ Having issues? Here are some common problems and their solutions:
 
 - **I'm hitting an UV error related to `[[ packages ]]`**: This means you're likely using an outdated version of UV. Try updating to the latest version with: `uv self update`.
 - **I'm hitting an error about `No module named 'codegen.sdk.extensions.utils'`**: The compiled cython extensions are out of sync. Update them with `uv sync --reinstall-package codegen`.
-- **I'm hitting a `RecursionError: maximum recursion depth exceeded` error while parsing my codebase**: If you are using python 3.12, try upgrading to 3.13. If you are already on 3.13, try upping the recursion limit with `sys.setrecursionlimit(10000)`.
+- **I'm hitting a `RecursionError: maximum recursion depth exceeded` error while parsing my codebase**: 
+  - If you are using python 3.12, try upgrading to 3.13
+  - If you are already on 3.13:
+    - On Linux/macOS: The recursion limit is automatically increased
+    - On Windows: Try increasing the recursion limit with `sys.setrecursionlimit(10000)`
+    - If issues persist, consider using WSL for better compatibility
