# I/O mixin

The I/O mixin, `NDIOMixin`, adds `read` and `write` methods that us the astropy I/O registry.

The mixin itself simply creates the read/write methods; it does not register any readers or writers with the I/O registry. Subclasses of `NDDataBase` or `NDData` need to include this mixin, implement a reader and writer, and register it with the I/O framework. See I/O Registry (astropy.io.registry) for details.
