 If you find Orthanc useful and wish to contribute to its development,
 here are some tasks you can take in charge that would greatly help us:
 
-* Use Orthanc in the real life. ;)
-* Report possible problems together with sample DICOM images on the
-  `issue tracker
-  <https://bitbucket.org/sjodogne/orthanc/issues?status=new&status=open>`_.
-* Answer questions posted to the `mailing list
-  <https://groups.google.com/forum/#!forum/orthanc-users>`_.
-* Index external contributions on the "`Orthanc Contributed
-  <https://github.com/jodogne/OrthancContributed>`_" GitHub
-  repository, via pull requests.
-* Provide documentation and use cases (e.g. on `GitHub <https://github.com/jodogne/OrthancContributed>`_).
-* Share maintenance scripts (e.g. on `GitHub <https://github.com/jodogne/OrthancContributed>`_).
-* Advertise about Orthanc, and answer the `survey <http://www.orthanc-server.com/static.php?page=blog#survey>`_.
-* Package Orthanc and its associated plugins for more UNIX or
-  GNU/Linux distributions (e.g. RHEL, CentOS, SUSE...).
-* Improve and translate the `Wikipedia page
-  <https://en.wikipedia.org/wiki/Orthanc_(software)>`_ about Orthanc.
-* Interface Orthanc with other software (e.g. 3D Slicer,
-  Matlab/Octave, Python, Horos, dicompyler...). Check the `already
-  supported frameworks <http://www.orthanc-server.com/static.php?page=resources>`_.
-* Develop :ref:`C/C++ plugins extending the Orthanc core <plugins>`.  Here are some ideas
-  of possible plugins:
+* **Non-coding tasks**:
+  
+  - Use Orthanc in the real life. ;)
+  - Advertise about Orthanc, notably on social networks (we are active
+    on `Facebook <https://www.facebook.com/orthancdicom/>`__ and
+    `Twitter <https://twitter.com/OrthancServer>`__).
+  - Answer our `survey
+    <http://www.orthanc-server.com/static.php?page=blog#survey>`_.
+  - Improve and translate the `Wikipedia pages
+    <https://en.wikipedia.org/wiki/Orthanc_(software)>`_ about Orthanc.
+  - Answer questions posted to the `mailing list
+    <https://groups.google.com/forum/#!forum/orthanc-users>`_.
+  - Provide documentation and use cases (inside the dedicated `GitHub
+    repository <https://github.com/jodogne/OrthancContributed>`_, via
+    pull requests).
+  - Index external contributions inside the `Links.md
+    <https://github.com/jodogne/OrthancContributed/blob/master/Links.md>`_
+    file.
+
+* **Maintenance tasks**:
+      
+  - Report problems together with sample DICOM images and possible
+    workarounds on the `issue tracker
+    <https://bitbucket.org/sjodogne/orthanc/issues?status=new&status=open>`_.
+  - Package Orthanc and its associated plugins for more UNIX or
+    GNU/Linux distributions (e.g. RHEL, CentOS, openSUSE...).
+  - Share your maintenance scripts or sample code inside the "`Orthanc Contributed
+    <https://github.com/jodogne/OrthancContributed>`_" public GitHub
+    repository, via pull requests.
+  - Improve the text of the `Orthanc Book
+    <https://bitbucket.org/sjodogne/orthanc-book/src/default/Sphinx/source/>`_.
+  - The Orthanc project will also happily accept **external patches**
+    in the core of Orthanc and in its associated official
+    plugins. Such patches can either be sent to the `mailing list
+    <https://groups.google.com/forum/#!forum/orthanc-users>`_ or via a
+    `pull request <https://bitbucket.org/sjodogne/orthanc/pull-requests/>`_.
 
-  * Check the TODO file of the `official roadmap <https://bitbucket.org/sjodogne/orthanc/src/default/TODO>`__.
-  * Create a :ref:`more advanced Web interface <improving-interface>` than the built-in Orthanc Explorer.
-  * Extend the :ref:`sample modality worklist plugin <worklist>` so that it manages the worklists
-    (i.e. add/remove items) with a REST API or HL7 messages, instead of reading them from 
-    some folder on the filesystem.
-
-* Have a look at the `Orthanc Wishlist board <https://trello.com/b/gcn33tDM/orthanc-wishlist>`__,
-  where users can submit their ideas for the future features of Orthanc.

-Always remember that he **recommended way of contributing to the source code of Orthanc is
-by creating C/C++ plugins**. If the current plugin SDK is insufficient
-for you to develop some feature as a plugin, do not hesitate to
-request an extension to the Orthanc SDK on the `mailing list
