 Serialized datapackages cannot contain executable code, both because of our chosen data formats, and for security reasons. Therefore, when loading a datapackage with an interface, that interface object needs to be reconstituted as Python code - we call this cycle dehydration and rehydration. Dehydration happens automatically when a datapackage is finalized with `finalize_serialization()`, but rehydration needs to be done manually using `rehydrate_interface()`. For example:
 
 ```python
-from fs.zipfs import ZipFS
+from fsspec.implementations.zip import ZipFileSystem
 from bw_processing import load_datapackage
 
-my_dp = load_datapackage(ZipFS("some-path.zip"))
