+Implements the Xorshift random number generator.
+
+The Xorshift[^1] algorithm is not suitable for cryptographic purposes
+but is very fast. If you do not know for sure that it fits your
+requirements, use a more secure one such as `StdRng` or `OsRng`.

+## Crate Features
+
+`rand_xorshift` is `no_std` compatible. It does not require any functionality
+outside of the `core` lib, thus there are no features to configure.
+
+The `serde1` feature includes implementations of `Serialize` and `Deserialize`
+for the included RNGs.
