+
+## How to Write Plugins
+
+Plugins are used to generate a `link` Object according to the `links.args`.
+For example, the `github` plugin:
+
+```javascript
+(function(socialShare) {
+    socialShare.plugin('github', function(args) {
+        return {
+            url: 'https://github.com/' + args.id,
+            background: '#b5b5b5',
+            icon: 'fa-github'
+        };
+    });
+})(window.socialShare);
+```
+
+To use this plugin, simply set `plugin` to `"github"`, and specify the args:
+
+```js
+var links = [{
+    plugin: 'github',
+    args: {
+        id: 'harttle'
+    }
+}];
+```
+
+Which is equavalent to:
+
+```js
+var links = [{
+    url: 'https://github.com/harttle',
+    background: '#b5b5b5',
+    icon: 'fa-github'
+}];
+```
