+GitBook Sample Plugin
+==============
+
+This is a model for GitBook plugins.
+
+## How GitBook plugin works?
+
+A plugin for GitBook is a node package that can be published on [NPM](http://www.npmjs.org). It has to follow the name convention: `gitbook-plugin-*name*`.
+
+### package.json
+
+#### name
+
+The package name should begin with ```gitbook-plugin-```.
+
+Examples: `gitbook-plugin-mixpanel`, `gitbook-plugin-googleanalytics`.
+>>>>>>> a61a89e2f73e5cd1ce9b40a6df653bd82832a2ce
+
+#### engine
+
+The package.json should contain a `engine` field using [the standard norm](https://www.npmjs.org/doc/json.html#engines).
+
+```
+"engines": {
+    "gitbook": "*"
+}
+```
+
+For example if you want your plugin to supports only GitBook version supperior to 0.3.1:
+
+```
+"engines": {
+    "gitbook": ">=0.3.1"
+}
+```
+
+### entry point
+
+The plugin entry point should return an object with some metadata.
