+## Replacement
+
+You can (and should) replace this library with https://docs.rs/uuid/. The code whould look like this:
+
+```rust
+let uuid = Uuid::new_v3(&Uuid::nil(), b"Hello world!");
+let uuid = Uuid::new_v5(&Uuid::nil(), b"Hello world!");
+```
+
+Since generating a UUID v3 and v5 without namespace is non-standard you either have to stick with this library or rely on your own implementation of the following methods of this library:
+```
+generate_uuid
+generate_uuid_v3
+generate_uuid_v5
+```
