 [![Build Status](https://travis-ci.org/partikus/php-protobuf-encoder.svg?branch=master)](https://travis-ci.org/partikus/php-protobuf-encoder)
 
+Simple PHP library that allows you encode Protobuf Message to byte code. Additionally this library allows to encode/decode massage into single message.
+The implementation is based on [this article](http://eli.thegreenplace.net/2011/08/02/length-prefix-framing-for-protocol-buffers).
+  
+## How to use it?
+
+### Prepare Proto Message file
+
+```
+syntax = "proto3";
+
+package Your.Namespace;
+
+message DummyMessage {
+    string Title = 1;
+    string Description = 2;
+    string CreatedAt = 3;
+    string UpdatedAt = 4;
+}
+
+```
+
+### Generate PHP files
+
+```
+vendor/bin/protobuf --include-descriptors -i . -o src/ DummyMessage.proto
+```
+
+### Create PHP objects
+ 
+```
+$dummyMessage = Your\Namespace\DummyMessage::fromArray([
+    'Title' => 'Test 123',
+    'Description' => 'Description from the text',
+    'CreatedAt' => '2016-12-12 12:00:00',
+    'UpdatedAt' => '2016-12-12 13:00:00',
+]);
+
+$encoder = new ClearCode\Protobuf\ByteEncoder();
+/** @var \Protobuf\Stream $stream */
+$stream = $encoder->encode($dummyMessage);
+file_put_contents(__DIR__ . '/dummyMessage.pb.bin', $stream);
+```
