-                  Notice: The groupchat code is not working with the actual GNUnet release atm!

-          To make chatting a tiny bit easier and prettier, we need to install and compile additional software.
-     </p>
-     <p>
-          First we have to install the Nim programming language. Please refer to their <a href="https://nim-lang.org/install.html">project site</a> for further details. The preferred method is using you distributions package manager, e.g. for Debian it would look like this: 
-      </p>
-      <code>
-        $ sudo apt install nim<br>
-        $ nim --version<br>
-        Nim Compiler Version 1.2.2 [Linux: amd64]<br>
-        Compiled at 2020-06-16<br>
-        Copyright (c) 2006-2020 by Andreas Rumpf<br>
-        <br>
-        active boot switches: -d:release -d:nativeStackTrace<br>
-      </code>
-      <p>
-       If the displayed version is <b>1.2.2 or newer</b>, we have a compatible version and can continue downloading and compiling the groupchat. If the version is older (like on Ubuntu 18.04) we can install Nim using a tool called <i>choosenim</i>:
-      </p>
-      <code>
-          $ curl https://nim-lang.org/choosenim/init.sh -sSf | sh
-      </code>
-      <p>
-      Then we follow the onscreen instructions. More information can be found in the <a href="https://nim-lang.org/install.html">official documentation</a>.
-      </p>
-      <p>In the onscreen instructions you'll be ask to add a line to your bashrc - once you've done that, re-read your bash environment to make the change active: 
-      </p>
-      <code>
-        $ source ~/.bashrc
-      </code>
-      
-      <p>
-          After we have installed (and maybe upgraded) Nim we download and compile the GNUnet groupchat application:
-         </p>
-         <p>
-         <code>
-              $ git clone https://git.gnunet.org/groupchat.git<br>
-              $ cd groupchat<br>
-              $ make<br>
-         </code>
-         <p>
-         <p>
-            We can now try to enter a chat server running on another GNUnet node using the command:
-         </p>
-         <p>
-         <code>
-               $ LD_LIBRARY_PATH=/path/to/gnunetlibs ./groupchat --config=/path/to/gnunet.conf --server=88RXABKJNMT426FY81N2DXN0M2X37SW5Q1NR005YPDZ1Q7A22CHG --port=t3ss --nick=YOURNICK<br>
-         </code>
-         <p>
-              The peer key and port name given in this example should work as they are almost always online and running groupchat on port "t3ss".

+        <p>
+          To make chatting a tiny bit easier and prettier, we need to install additional software.
+        </p>
+        <p>
+          You can select one of the options listed <a href="applications.html">here</a> under applications 
+          using the Messenger service. Those are generally compatible with each other using the same 
+          underlying <a href="https://git.gnunet.org/libgnunetchat.git/">library</a> but tell apart in their 
+          user interface and design.
+        </p>
+        <p>
+          In other words: You can choose by your own preference how to chat.
+        </p>
+        <p>
+          After you have picked an application (for example <a href="https://git.gnunet.org/messenger-gtk.git/">Messenger-GTK</a> 
+          or <a href="https://git.gnunet.org/messenger-cli.git/">messenger-cli</a>), follow the instructions for build and installation.
+          Notice that depending on the picked application, you might need additional dependencies besides the library for the chatting
+          functionality.
+        </p>
+        <p>
+          Once you installed the application and started it, a dialog should open to ask you for an account to use or whether you want 
+          to create a new one. An account is pretty much an identity which can also be used for <a href="#gns_cli">GNS</a> capabilities.
+          Accounts don't require any information besides a chosen identifier or nick.
+        </p>
+        <p>
+          Next step is to enter a chat room via your application. The easiest step is choosing a public chat room which is similar to 
+          communicate via <a href="#cadet">CADET</a> through a shared port. Look for a function to add a new room or "platform".
+          You should be able to enter any sort of text as key for the room and confirm.
+        </p>
+        <p>
+          A chat room should open using the entered key as identifier and any other person you share the key with should be able to join
+          this room as well using one of the compatible applications as linked above. From here you can simply write text in a proper field
+          and send it as a message to communicate.
+        </p>
+        <p>
+          In case of any more advanced functionality it is recommended to look for a guide or more detailed information on the source of the
+          used application since implementations can vary, especially the design of user interface.
+        </p>
+        <p>
+          Also you can always use the simplified command line tool `gnunet-messenger` provided by GNUnet itself to open or join a chat with
+          its key in a similar way as described above. See the more detailed information in the 
+          <a href="https://docs.gnunet.org/handbook/gnunet.html#Using-the-GNUnet-Messenger">handbook</a> to use it.

         <p>The GNU Name Service (GNS) is a fully decentralized alternative to the Domain Name System (DNS). Where GNS does not suffer the same major <a href="https://en.wikipedia.org/wiki/Domain_Name_System#Security_issues">security flaws as DNS</a>.
