   <h1>KST4Contest Manual</h1>

   <p>
-    User documentation for installation, configuration, features,
-    AirScout integration, log synchronization and contest workflow.
+    The manual describes the controls and interfaces of KST4Contest as well as
+    the reasoning behind functions that derive information from chat messages,
+    station data or external programs. Where a result depends on incomplete
+    information, the corresponding limitations are described as well.

+      <p>
+        The Stable build is normally the appropriate choice for contest
+        operation. Beta and Nightly builds are useful when a specific correction
+        or new function needs to be tested. Test them before the contest rather
+        than during its first minutes.
