+Protobuf for PHP
+================
 
+Protobuf for PHP is an implementation of Google's Protocol Buffers for the PHP
+language, supporting its binary data serialization and including a `protoc` 
+plugin to generate PHP classes from .proto files.
+
+Great effort has been put into generating PHP files that include all sort of type
+hints to aide IDE's with autocompletion. Therefore, it can not only be used to
+communicate with Protocol Buffers services but also as a generation tool for 
+_data objects_ no matter what the final serialization is.
+
+For more information see the [included man pages](http://drslump.github.com/Protobuf-PHP/).
+
+
+## Requirements
+
+  - PHP 5.3  
+  - Pear's Console_CommandLine (for the protoc wrapper tool)
+  - Google's `protoc` compiler version 2.3 or above
+  - GMP or BC Math extensions ¹
+
+  ¹ Only needed for negative values in `int32`, `int64` or `fixed64` types. See
+    the _known issues_ section.
+
+
+## Features
+
+### Working
+
+  - Standard types (numbers, string, enums, messages, etc)
+  - Pluggable serialization backends (codecs)
+    - Standard Binary
+    - Standard TextFormat ¹
+    - PhpArray
+    - JSON
+    - [ProtoJson](https://github.com/drslump/ProtoJson) (_TagMap_ and _Indexed_ variants)
+    - XML
+  - Protoc compiler plugin to generate the PHP classes
+  - Extensions
+  - Unknown fields
+  - Packed fields
+  - Reflection
+  - Dynamic messages with annotations support
+  - Generates service interfaces
+  - Includes comments from .proto files in the generated files
+  - Pear package for easy installation
+
+¹ Only serialization is supported
+
+### Future
+
+  - Speed optimized code generation mode
+  - Support numbers beyond PHP's native limits
+
+
+
+## Example usage
+
+    $person = new Tutorial\Person();
+    $person->name = 'DrSlump';
+    $person->setId(12);
+
+    $book = new Tutorial\AddressBook();
+    $book->addPerson($person);
+
+    // Use default codec
+    $data = $book->serialize();
+
+    // Use custom codec
+    $codec = new \DrSlump\Protobuf\Codec\Binary();
+    $data = $codec->encode($book);
+    // ... or ...
+    $data = $book->serialize($codec);
+
+
+## Installation
+
+Install with Pear
+
+    pear channel-discover pear.pollinimini.net
+    pear install drslump/Protobuf-beta
+
+You can also get the latest version by checking out a copy of the
+repository in your computer.
+
+
+
+## Known issues
+
+
+### Types
+
+PHP is very weak when dealing with numbers processing. Several work arounds have been applied
+to the standard binary codec to reduce incompatibilities between Protobuf types and PHP ones.
+
+  - Protobuf stores floating point values using the [IEEE 754](http://en.wikipedia.org/wiki/IEEE_754) standard
+    with 64bit words for the `double` and 32bit for the `float` types. PHP supports IEEE 754 natively although
+    the precission is platform dependant, however it typically supports 64bit doubles. It means that
+    if your PHP was compiled with 64bit sized doubles (or greater) you shouldn't have any problem encoding
+    and decoded float and double typed values with Protobuf.
+
+  - Integer values are also [platform dependant in PHP](http://www.php.net/manual/en/language.types.integer.php).
+    The library has been developed and tested against PHP binaries compiled with 64bit integers. The encoding and
+    decoding algorithm should in theory work no matter if PHP uses 32bit or 64bit integers internally, just take
+    into account that with 32bit integers the numbers cannot exceed in any case the `PHP_INT_MAX` value (2147483647).
+
+    While Protobuf supports unsigned integers PHP does not. In fact, numbers above the compiled PHP maximum
+    integer (`PHP_INT_MAX`, 0x7FFFFFFFFFFFFFFF for 64bits) will be automatically casted to doubles, which
+    typically will offer 53bits of decimal precission, allowing to safely work with numbers upto
+    0x20000000000000 (2^53), even if they are represented in PHP as floats instead of integers. Higher numbers
+    will loose precission or might even return an _infinity_ value, note that the library does not include
+    any checking for these numbers and using them might provoke unexpected behaviour.
+
+    Negative values when encoded as `int32`, `int64` or `fixed64` types require the big integer extensions
+    [GMP](http://www.php.net/gmp) or [BC Math](http://www.php.net/bc) (the later only for 64bit architectures)
+    to be available in your PHP environment. The reason is that when encoding these negative numbers without
+    using _zigzag_ the binary representation uses the most significant bit for the sign, thus the numbers become
+    above the maximum supported values in PHP. The library will check for these conditions and will automatically
+    try to use GMP or BC to process the value.
+
+
+### Strings
+
+The binary codec expects strings to be encoded using UTF-8. PHP does not natively support string encodings,
+PHP's string data type is basically a length delimited stream of bytes, so it's not trivial to include
+automatic encoding conversion into the library encoding and decoding routines. Instead of trying to guess
+or offer a configuration interface for the encoding, the binary codec will process the `string` type just as
+it would process `byte` one, delegating on your application the task of encoding or decoding in the desired
+character set.
+
+### Memory usage
+
+Large messages might be troublesome since the way the library is modelled does not allow to parse or
+serialize messages as a streams, instead the whole operation is performed in memory, which allows for faster
+processing but could consume too much RAM if messages are too large.
+
+
+### Unknown fields
+
+Since wire types are different across different codec's formats, it's not possible to transcode unkwnon
+fields consumed in one codec to another. This means, for example, that when consuming a message using the
+binary codec, if it contains unknown fields, they won't be included when serializing the message using the
+Json codec.
+
+
+## Generating PHP classes
+
+The generation tool is designed to be run as a `protoc` plugin, thus it should
+work with any proto file supported by the official compiler.
+
+    protoc --plugin=protoc-gen-php --php_out=./build tutorial.proto
+
+To make use of non-standard options in your proto files (like `php.namespace`) you'll
+have to import the `php.proto` file included with the library. It's location will 
+depend on where you've installed this library.
+
+    protoc -I=./Protobuf-PHP/library/DrSlump/Protobuf/Compiler/protos \
+           --plugin=protoc-gen-php --php_out=./build tutorial.proto
+
+In order to make your life easier, the supplied protoc plugin offers an additional
+execution mode, where it acts as a wrapper for the `protoc` invocation. It will
+automatically include the `php.proto` path so that you don't need to worry about it.
+
+    protoc-gen-php -o ./build tutorial.proto
