+# Database Binding
+This binding provide a database API with key/value semantics.
+The backend is currently a Berkeley DB.
+
+## Verbs
+* **insert**:
+	This verb insert a key/value pair in the database.
+	If the key already exist, the verb fails.
+	
+* **update**:
+	This verb update an existing record.
+	If the key doesn't exist, the verb fails.
+	
+* **delete**:
+	This verb remove an existing key/value pair from the database.
+	If no matching record is found, the verb fails.
+
+* **read**:
+	This verb get the value associated with the specified key.
+	If no matching record is found, the verb fails.
+
+## Arguments
+* The **read** and **delete** verbs need only a **key** to work:
+```
+{
+	"key": "mykey"
+}
+```
+
+* The **insert** and **update** verbs need a **key** and a **value** to work:
+```
+{
+	"key": "mykey",
+	"value": "my value"
+}
+```
+The **value** can be any valid json.

-# Database Binding
-This binding provide a database API with key/value semantics.
-The backend is currently a Berkeley DB.
-
-## Verbs
-* **insert**:
-	This verb insert a key/value pair in the database.
-	If the key already exist, the verb fails.
-	
-* **update**:
-	This verb update an existing record.
-	If the key doesn't exist, the verb fails.
-	
-* **delete**:
-	This verb remove an existing key/value pair from the database.
-	If no matching record is found, the verb fails.
-
-* **read**:
-	This verb get the value associated with the specified key.
-	If no matching record is found, the verb fails.
-
-## Arguments
-* The **read** and **delete** verbs need only a **key** to work:
-```
-{
-	"key": "mykey"
-}
-```
-
-* The **insert** and **update** verbs need a **key** and a **value** to work:
-```
-{
-	"key": "mykey",
-	"value": "my value"
-}
-```
-The **value** can be any valid json.
