+<h2>Overview</h2>
+<p style="margin-top: 1em;">
+LuaJIT has been successfully used as a <b>scripting middleware</b> in
+games, appliances, network and graphics apps, numerical simulations,
+trading platforms and many other specialty applications.
+</p>
+<p>
+LuaJIT is part of a hundred million web sites, huge SaaS installations,
+network switches, set-top boxes and other embedded devices. You've probably
+already used LuaJIT without knowing about it.
+</p>
+<p>
+LuaJIT scales from embedded devices, smartphones, desktops up to server
+farms. It combines high flexibility with high performance and an unmatched
+<b>low memory footprint</b>.
+</p>
+<p>
+LuaJIT has been in continuous development since 2005. It's widely
+considered to be <b>one of the fastest dynamic language
+implementations</b>. It has outperformed other dynamic languages on many
+cross-language benchmarks since its first release &mdash; often by a
+substantial margin.
+</p>
+<p>
+For <b>LuaJIT 2.0</b>, the whole VM has been rewritten from the ground up
+and relentlessly optimized for performance. It combines a <b>high-speed
+interpreter</b>, written in assembler, with a <b>state-of-the-art JIT
+compiler</b>.
+</p>
+<p>
+An innovative <b>trace compiler</b> is integrated with advanced,
+SSA-based optimizations and highly tuned code generation backends.
+A substantial reduction of the overhead associated with dynamic languages
+allows it to break into the performance range traditionally reserved for
+offline, static language compilers.
