+===========
 
 MurmurHash3 general hash bashed lookup function implementation
+
+## about
+
+[MurmurHash](http://en.wikipedia.org/wiki/MurmurHash) is a non-cryptographic hash function suitable
+for general hash-based lookup. This implementation implements version 3
+of MurmurHash.
+
+## install
+
+[clib](https://github.com/clibs/clib):
+
+```sh
+$ clib install jwerle/murmurhash.c
+```
+
+## example
+
+```c
+
+#include <stdlib.h>
+#include <string.h>
+#include <murmurhash.h>
+
+int
+main (void) {
+  uint32_t seed = 0;
+  const char *key = "kinkajou";
+  uint32_t hash = murmurhash(key, (uint32_t) strlen(key), seed); // 0xb6d99cf8
+  return 0;
+}
+```
+
+## api
+
+```c
+uint32_t
+murmurhash (const char *key, uint32_t len, uint32_t seed);
+```
+
+Returns a murmur hash of `key' based on `seed' using the MurmurHash3 algorithm.
