+## Options
+
+In the `options` property you'll need to add an object with a property `rss` which is an array of objects with the RSS informations you want to parse
+
+```js
+{
+  urlToFetch: "URL_TO_FETCH",
+  selectors: ["SELECTORS"],
+  name: "graphQLPropertyName",
+}
+```
+
+Use gatsby's `useStaticQuery` to retrieve datas

+{
+  allYouTubeRss {
+    nodes {
+      media_title
+      media_thumbnail
+    }
