+<h2 id="apolloquerypipe">ApolloQueryPipe</h2>
+
+Apollo client exposes queries as observables, but each Apollo query can include few queries.
+
+So inside an Apollo observable the data comes in the following form: `obs.data.queryName`
+
+To handle that more easily we've created the `ApolloQueryPipe`. here is how it works:
+
+template:
+```html
+<ul>
+  <li *ngFor="#post of posts | async | apolloQuery:'posts'">
+      {{ post.title }}
+  </li>
+</ul>
+```
+
+We are pondering about a solution that will return an observable per single query and then we won't need that pipe anymore.

+import {
+  Component, Injectable
+} from 'angular2/core';
+
+import {
+  Angular2Apollo
+} from 'angular2-apollo';
+
+import {
+  graphQLResult
+} from 'graphql';
+
+@Component({
+  selector: 'postsList',
+  templateUrl: 'client/postsList.html'
+})
+@Injectable()
+class postsList {
+  constructor(private angularApollo : Angular2Apollo) {

+  postReply({
+    token,
+    topicId,

+        topic_id: topicId,
+        category_id: categoryId,
+        raw: raw,
+      }
