+ The servers are listed / edited  in a grid. 
+
+ <ul>
+  <li>To edit a cell, double click on it. After a cell is changed it
+      will flags one of its corner to red to indicated that it has been
+      changed. To commit these changes back to Tvheadend press the 
+      'Save changes' button. In order to change a Checkbox cell you only
+      have to click once in it.
+
+  <li>To add a new entry, press the 'Add entry' button. The new (empty) entry
+      will be created on the server but will not be in its enabled state.
+      You can now change all the cells to the desired values, check the
+      'enable' box and then press 'Save changes' to activate the new entry.
+
+  <li>To delete one or more entries, select the lines (by clicking once on 
+      them), and press the 'Delete selected' button. A pop up
+      will ask you to confirm your request.
+ </ul>
+
+ <p>
+ The columns have the following functions:
+
+ <dl>
+  <dt>Enabled
+  <dd>If selected, connection will be tried to be established and retained up.
+      If unselected, Tvheadend will disconnect (if connected) and not try to reconnect.
+
+  <dt>Camd.socket Filename
+  <dd>Socket filename which is usually opened by cam client. Tvheadend
+      tries to connect to this socket file.
+
+  <dt>Listenport
+  <dd>If running on a so called full-featured DVB-Card this can be left
+      empty.
+      Running on Budget-Cards one has to use a dummy ca-device. This is
+      emulated via capmt_ca.so. This module has to be pre-loaded prior to
+      the cam client.
