# Advanced config

If you want to disable os-related features, you can do this before including pocketpy.h.

#define PK_ENABLE_OS 0
#include <pocketpy.h>

You can create a user_config.h in the same directory as pocketpy.h to override some default settings.

1. Copy src/config.h and rename it to user_config.h.
2. Define a macro PK_USER_CONFIG_H in user_config.h. This invalidates the default config.h and enables your user_config.h.
3. Edit user_config.h to override default settings.
