    <para>
-     &TODO;
+    An interactive definition is started by giving a
+    <link linkend="definition">definition</link> command omitting
+    the definiens.
+    An interactive proof is started by using one of the
+    <link linkend="proofs">proof commands</link> omitting
+    an explicit proof term.
    </para>
+   <para>An interactive proof or definition can and must be terminated by
+    a <link linkend="command_qed">qed</link> command when no more sequents are
+    left to prove. Between the command that starts the interactive session and
+    the qed command the user must provide a procedural proof script made
+    of <link linkend="sec_tactics">tactics</link> structured by means of
+    <link linkend="tacticals">tacticals</link>.</para>
+   <para>In the tradition of the LCF system, tacticals can be considered
+    higher order tactics. Their syntax is structured and they are executed
+    atomically. On the contrary, in Matita the syntax of several tacticals is
+    destructured into a sequence of tokens and tactics in such a way that is
+    is possible to stop execution after every single token or tactic.
+    The original semantics is preserved: the execution of the whole sequence
+    yields the result expected by the original LCF-like tactical.</para>
