+=======================
+Guzzle OAuth 2.0 Subscriber
+=======================
+
+This is an OAuth 2.0 client for Guzzle which aims to be 100% compatible with Guzzle 4, 5, 6 and all future versions within a single package.
+Although I love Guzzle, its interfaces keep changing, causing massive breaking changes every 12 months or so, so I have created this package
+to help reduce the dependency hell that most third-party Guzzle dependencies bring with them.  I wrote the official Guzzle OAuth 2.0 plugin
+which is still on the `oauth2` branch, [over at the official Guzzle repo](https://github.com/guzzle/oauth-subscriber/tree/oauth2), but I
+see that they have dropped support for Guzzle < v6 on `master`, which prompted me to split this back off to a separate package.
+
+Installing
+==========
+
+This project can be installed using Composer. Add the following to your
+composer.json:
+
+```javascript
+    {
+        "require": {
+            "kamermans/guzzle-oauth2-subscriber": "~1.0"
+        }
+    }
+```
