 ## Usage
-Need to update...
+There are two ways to embed share buttons to page.
+First, you can add share buttons one by one. Example:
+
+    {{#fb-share-button}}Share{{/fb-share-button}}
+    {{#vk-share-button}}Share{{/vk-share-button}}
+    {{#twitter-share-button}}Tweet{{/twitter-share-button}}
+
+Or you can add share buttons like one share panel:
+
+    {{share-panel buttons="fb,vk,twitter" labels="Share,Share,Tweet"}}
+
+There are some properties for ```share-panel```:
+
+* _buttons_ - comma-separated list of social networks
+* _labels_ - comma-separated list of buttons labels
+
+At section below you can find share options that can be set for each button or panel.
