+
+**Native Client** is a sandbox for running compiled C and C++ code in the
+browser efficiently and securely, independent of the user's operating system.
+**Portable Native Client** extends that technology with
+architecture independence, letting developers compile their code once to run
+in any website and on any architecture.
+
+In short, Native Client brings the **performance** and **low-level control**
+of native code to modern web browsers, without sacrificing the **security** and
+**portability** of the web. Watch the video below for an overview of
+Native Client, including its goals, how it works, and how
+Portable Native Client lets developers run native compiled code on the web.
