 For general information, check out the `official homepage of the
 plugin <http://www.orthanc-server.com/static.php?page=web-viewer>`__.
+
+
+Compilation
+-----------
+
+.. highlight:: text
+
+The procedure to compile these plugins is similar of that for the
+:ref:`core of Orthanc <compiling>`. The following commands should work
+for every UNIX-like distribution (including GNU/Linux)::
+
+  $ mkdir Build
+  $ cd Build
+  $ cmake .. -DSTATIC_BUILD=ON
+  $ make
+
+The compilation will produce a shared library ``OrthancWebViewer``
+that contains the Web viewer plugin.  Pre-compiled binaries for
+Microsoft Windows `are also available
+<http://www.orthanc-server.com/browse.php?path=/plugin-webviewer>`__.
+
+
+Usage
+-----
+
+.. highlight:: json
+
+You of course first have to :ref:`install Orthanc <compiling>`. Once
+Orthanc is installed, you must change the :ref:`configuration file
+<configuration>` to tell Orthanc where it can find the plugin: This is
+done by properly modifying the ``Plugins`` option. You could for
+instance use the following configuration file::
+
+  {
+    "Name" : "MyOrthanc",
+    [...]
+    "Plugins" : [
+      "/home/user/OrthancWebViewer/Build/libOrthancWebViewer.so"
+    ]
+  }
+
+.. highlight:: text
+
+Orthanc must of course be restarted after the modification of its
+configuration file. The log will contain an output similar to::
+
+  # Orthanc ./Configuration.json

+
+Once a :ref:`DICOM series <model-world>` is opened using Orthanc
+Explorer, a yellow button entitled ``Orthanc Web Viewer`` will show
+up. It will open the Web viewer for that particular series.  See also
+the demonstration video on `official homepage of the plugin
+<http://www.orthanc-server.com/static.php?page=web-viewer>`__.
+
+
+Advanced options
+----------------
+
+.. highlight:: json
+
+The configuration of the Web viewer can be fine-tuned by adding some options::
+
+  {
+    "Name" : "MyOrthanc",
+    [...]
+    "Plugins" : [
+      "/home/user/OrthancWebViewer/Build/libOrthancWebViewer.so"
+    ],
+    "WebViewer" : {
+      "CachePath" : "WebViewerCache",
+      "CacheSize" : 10,
+      "Threads" : 4
+    }
+  }
+
+* ``CachePath`` specifies the location of the cache of the Web
+  viewer. By default, the cache is located inside the storage
+  directory of Orthanc.
+* ``CacheSize`` specifies the maximum size for the cached images, in
+  megabytes. By default, a cache of 100 MB is used.
+* ``Threads`` specifies the number of threads that are used by the
+  plugin to decode the DICOM images.
