+A pure Elixir implementation of [Google Protobuf](https://developers.google.com/protocol-buffers/).
 
 ## Why this instead of exprotobuf(gpb)?
 
 It has some must-have and other cool features like:
 
 1. A protoc [plugin](https://developers.google.com/protocol-buffers/docs/cpptutorial#compiling-your-protocol-buffers) to generate Elixir code just like what other official libs do, which is powerful and reliable.
-2. Generate **simple and explicit** code with the power of Macro. (see [test/support/test_msg.ex](https://github.com/tony612/protobuf-elixir/blob/master/test/support/test_msg.ex))
+2. Generate **simple and explicit** code with the power of Macro. See [test/support/test_msg.ex](https://github.com/tony612/protobuf-elixir/blob/master/test/support/test_msg.ex).
 3. Plugins support. Only [grpc](https://github.com/tony612/grpc-elixir) is supported now.
 4. Use **structs** for messages instead of Erlang records.
 5. Support Typespec in generated code.
