+
+A rust implementation of the MurmurHash3_. Both 32 bit and 128 bit versions are included. The 128
+bit version is implemented with 64 bit datatypes, making it most suitable for x86_64 or other 64 bit
+architectures.
+
+----
+
+Usage
+=====
+
+In your ``Cargo.toml``:
+
+.. code:: toml
+
+    [dependencies]
+    murmurhash3 = "*"
+
+Then you can start to use either ``murmurhash3_x86_32`` or ``murmurhash3_x64_128``:
+
+.. code:: rust
+
+    use murmurhash3::murmurhash3_x64_128;
+
+    fn hash_value() {
+        let data = "test data";
+        let seed = 48221234;
+
+        let hash = murmurhash3_x64_128(data.as_bytes(), seed);
+    }
+
+Unfortunately, there is a bug in the ``HashState`` library implementation which prevents
+implementation of new ``Hasher`` implementations for use in for example ``HashMap``. Additionally,
+only the 32 bit hasher can be used there since ``HashMap`` uses a 64 bit hash internally.
+
+Tests
+=====
+
+.. code::
+
+    cargo test
+
+Runs all tests with optimization level 3 in order to weed out potential problems with the optimizer.
