+
+## Long Term Support
+
+Each major version of this library will be supported for 5 years after it's initial release. Support will be provided for security and bug fixes.
+
+Version 1 will therefore be supported until the 11th September 2019.
+
+## Background
+
+I wanted a replacement for Base64 encoded strings and the [Base58 encoding used by Bitcoin](https://en.bitcoin.it/wiki/Base58Check_encoding) looked ideal. I looked around for an existing PHP library which would directly convert a string into Base58 but I couldn't find one, or at least one that worked correctly and was also well tested.
+
+So I decided to create a library with the following goals:
+
+- Encode/Decode PHP Strings
+- Simple and easy to use
+- Fully Tested
+- Available via Composer
+
+## Requirements
+
+This library has the following requirements:
+
+- PHP => 5.3
+- BC Math Extension
+
+## Installation
+
+I recommend you install this library via Composer.
+
+```json
+{
+    "require": {
+        "stephenhill/base58": "~1.0"
+    }
+}
+```
+
+## Basic Usage
+
+```php
+require_once('vendor/autoload.php');
+
+$base58 = new StephenHill\Base58();
+
+$base58->encode('Hello World');
+$base58->decode('JxF12TrwUP45BMd');
+```
+
+## Advanced Usage
+
+By default this library chooses the encoding service provider to use, either GMPService or BCMathService (in that order).
+If you want to specify one of the included services or your own, you can inject it into the constructor.
+
+```php
+require_once('vendor/autoload.php');
+
+$gmp = new StephenHill\GMPService();
+$base58 = new StephenHill\Base58(null, $gmp);
+
+$base58->encode('Hello World');
+$base58->decode('JxF12TrwUP45BMd');
+```
+
+Also by default, this library uses Bitcoin's Base58 alphabet. If you want to use another variant, you can do this in the constructor.
+
+```php
+require_once('vendor/autoload.php');
+
+// Flickr's Base58 Alphabet
+$base58 = new StephenHill\Base58('123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ');
+
+$base58->encode('Hello World');
+$base58->decode('iXf12sRWto45bmC');
+```
+
+## Testing
+
+This library is tested using PHPUnit.
+
+```bash
+$ bin/phpunit
+```
+
+## Benchmarking
+
+You can benchmark this library using [Athletic](https://github.com/polyfractal/athletic).
+The benchmarking suite also benchmarks PHP's built-in Base64 and Base16 encoding for comparison.
+
+```bash
+$ bin/athletic -p benchmarks
+```
+
+Example output.
