 SnappyDB
 ========
 
-A key-value database for Android
+SnappyDB is a __key-value__ database for Android 
+it's an alternative for _SQLite_ if you want to use a __NoSQL__ approach.
+
+It allows you to store and get _primitive types_, but also a _Serializable_ object or array in a __type-safe__ way.
+
+SnappyDB can outperform _SQLite_ in read/write operations.
+![benchmark](http://snappydb.com/img/benchmark_sqlite_with_transaction.png)
+
+
+SnappyDB is based on [leveldb](https://code.google.com/p/leveldb/) and use [snappy compression](https://code.google.com/p/snappy/) algorithm, on redundant content you could achieve a good compression ratio 
+
+
+
+
+Usage
+-----
+
+ ```java
+try {
+	DB snappydb = DBFactory.open(context); //create or open an existing databse using the default name
+
+	snappydb.put("name", "Jack Reacher"); 
+	snappydb.putInt("age", 42); // 
+	snappydb.putBoolean("single", true);
+	snappydb.put("books", new String[]{"One Shot", "Tripwire", "61 Hours"}); 
+
+	String 	 name   =  snappydb.get("name");
+	int 	 age    =  snappydb.getInt("age");
+	boolean  single =  snappydb.getBoolean("single");
+	String[] books  =  snappydb.getArray("books", String.class);// get array of string
+
+	} catch (SnappydbException e) {
+	}
+ ```
+
+For more recipes please take a look at the [Cookbook].
+
+With SnappyDB you could seamlessly store and retrieve your object/array, it use [Kryo](https://github.com/EsotericSoftware/kryo) serialization which it [faster](https://github.com/eishay/jvm-serializers/wiki) than regular Java serialization.
+
+
