-# yii2-jsonrpc
+# yii2-jsonrpc
+
+This is Yii2-based JSON-RPC server implementation. CURRENTLY IN DEVELOPMENT. CONTRIBUTION WELCOME.
+
+## Features
+* Uses full Yii2 power, because method string is translated into a route. You can keep using all the Yii2 feature
+such as routing, access control, etc.
+Examples:
+`{jsonrpc: "2.0", "method": "foo", "id": 1} -> route /foo -> {action: foo, controller: index, module: default}`
+`{jsonrpc: "2.0", "method": "foo.bar": "id": 2} -> route /foo/bar -> {action: bar, controller: foo, module: default}`
+`{jsonrpc: "2.0", "method": "foo.bar.baz": "id": 3} -> route /foo/bar/baz -> {action: baz, controller: bar, module: foo}`
+* Supports batch processing.
