+# sebastian/diff
+
+Diff implementation for PHP, factored out of PHPUnit into a stand-alone component.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+ composer require sebastian/diff
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+ composer require --dev sebastian/diff
+
+### Usage
+
+The `Differ` class can be used to generate a textual representation of the difference between two strings:
+
+```php
+use SebastianBergmann\Diff\Differ;
+
+$differ = new Differ;
+print $differ->diff('foo', 'bar');
+```
+
+The code above yields the output below:
+
+ --- Original
+ +++ New
+ @@ @@
+ -foo
+ +bar
+
+The `Parser` class can be used to parse a unified diff into an object graph:
+
+```php
+use SebastianBergmann\Diff\Parser;
+use SebastianBergmann\Git;
+
+$git = new Git('/usr/local/src/money');
+
+$diff = $git->getDiff(
+ '948a1a07768d8edd10dcefa8315c1cbeffb31833',
+ 'c07a373d2399f3e686234c4f7f088d635eb9641b'
+);
+
+$parser = new Parser;
+
+print_r($parser->parse($diff));
+```
+
+The code above yields the output below:
