+    <title>Scope</title>
+    <p>Debugger is a graphical user interface for the Erlang
+      interpreter, which can be used for debugging and testing of
+      Erlang programs. For example, breakpoints can be set, code can be
+      single-stepped and variable values can be displayed and changed.
+    </p>
+
+    <p>The Erlang interpreter can also be accessed through the interface
+      module <seealso marker="int"><c>int(3)</c></seealso>.
+    </p>
+
+    <warning>
+      <p>Debugger might at some point
+      start tracing on the processes that execute the interpreted
+      code. This means that a conflict occurs if tracing by other
+      means is started on any of these processes.</p>
+    </warning>

+  <section>
+    <title>Prerequisites</title>
+    <p>It is assumed that the reader is familiar with the Erlang
+      programming language.</p>
+    <p>Modules to be debugged must include debug information,
+      for example, <c>erlc +debug_info MODULE.erl</c>.</p>
