+### Compatibility with SMB1 and AFP
+
+This library does not support `SMB1` and will not support SMB 1.0 in the near future, this is due to SMB1 and SMB2 are not compatible, with completely different packet structures.
+
+Relatedly, connecting to macOS servers using pre-SMB, Apple Filing Protocol ([AFP](https://en.wikipedia.org/wiki/Apple_Filing_Protocol)) is not supported. 
+
+`OS X 10.9 Mavericks` and later supports SMB as the primary file sharing protocol.
