The asdf-astropy package contains code that is used to serialize
types so that they can be represented and stored using the Advanced Scientific
Data Format (ASDF).
If asdf-astropy is installed, no further configuration is required in order to process ASDF files that contain astropy types. Note that the asdf package has been designed to automatically detect the presence of tags defined by packages like asdf-astropy and automatically make use of that package’s support infrastructure to operate correctly.
