 <p>In both cases you have a text box to type a message. Click inside it, type a notice, then click <i>Send</i> to publish it to your followers.</p>

+<p>After you have followed a few of your friends and interesting people on the network you will see their posts on your "HOME" newsfeed. Below each post are some icons that allow you to interact with the notice and/or the original poster.</p>
+
+<p>Clicking on the <img src="{RES:reply.gif}"> will add a post text field to the page and allow you to respond to the post. Your reply will then appear as a threaded notice underneath the original post, as in this example:</p>
+
+<a href="{RES:reply_example_1.png}">
+<img src="{RES:reply_example_1.png}" alt="Replying to a notice" class="figure" />
+</a>
+
+<p>Clicking on the <img src="{RES:favourite.gif}"> will add the post to your list of favourite posts. This also pings the original poster alerting them that you favourited the post. You can see your list of favourite posts by clicking on the "FAVOURITES" link on the left navigation bar. If you are using <a href="https://github.com/chimo/gs-reverseFavs">Chimo's Reverse Favourites</a> plugin you can see who has favourited your previous posts.
+
+<p>Clicking on the <img src="{RES:recycle.gif}"> will repeat the notice so that it will be shared to your own list of followers, and as such probably implies another more explicit favour to the original post.</p>
+
+{HEADING:SUBSECTION:groups_tags:Hashtags, Mentions and Groups}
+
+<p>In addition to the above methods to interact with followers network, GNUSocial also supports features you will find familiar with other social networks. You can mention someone else in a post by using the '@' prefix. This example shows how to mention someone, and how the post will look after you post it.<p>
+
+<a href="{RES:mention_example_1.png}">
+<img src="{RES:mention_example_1.png}" alt="Mentioning a user in a post" />
+</a>
+
+<p>You don't have to use the full 'username@domain.tld' format when mentioning someone. If you leave out the full '@domain.tld' part of a user you are mentioning then you are limiting the scope to people on your local instance and your followers.
+
+<p>The social network hashtag '#' prefixed before a word, eg #federated makes keywords trend on your home feed and across the federated network as more people use the same hashtag</p>
+
+<p>Groups are an optional part of GNUSocial. Each social instance can have one or more groups based on a topic. Then local users of the instance as well as remote social users can subscribe to the group. A group is similar to a user in GNUSocial but you refer to a group using the '!' prefix instead of the '@' prefix.</p>
+
+<p>When you find a group on your local GNUSocial instance, or a remote instance you can follow it in a similar way to following users, simply enter your GNUSocial username when prompted after clicking on the "Join" button.</p>
+
+<p>You can post a notice to the group by mentioning the group with a '!' prefix, for example:</p>
+
+<a href="{RES:grouppost_example_1.png}">
+<img src="{RES:grouppost_example_1.png}" alt="Making a post mentioning a group." />
+</a>
+
+<p>Your post will then appear in your follower's feeds as well as anyone else subscribed to the group who may or may not also follow you.</p>
