+<h2>What is Isabelle?</h2>
Isabelle can be viewed from two main perspectives. On the one hand it
may serve as a generic framework for rapid prototyping of deductive
-systems. On the other hand, major object logics like
+systems. On the other hand, major existing logics like
<strong>Isabelle/HOL</strong> provide a theorem proving environment
ready to use for sizable applications.
