+Simple PHP wrapper for Git.
+
+## Installation
+
+To add this package as a local, per-project dependency to your project, simply add a dependency on `sebastian/git` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on Git 1.0:
+
+    {
+        "require": {
+            "sebastian/git": "1.0.*"
+        }
+    }
