+# The Monad Manifesto
+
+Jeffrey Snover, the inventor of PowerShell, wrote the Monad Manifesto to explain his vision for
+PowerShell and how it would change the way we manage systems. You can read more about why he wrote
+it in his [Monad Manifesto][02] blog post.
+
+In that post, he explained how hard it was to communicate the vision for PowerShell to widely
+distributed development teams. The development teams didn't understand the vision. Writing the
+Manifesto forced him to be clear about what problem was being addressed, the core principles of the
+design, how to address the issue, who would benefit from it, and why.
+
+Use the following link to download a copy of the Manifesto.

+- [Monad Manifesto][01].
+
+This document is historically significant to PowerShell. It's a version of the original Monad
+Manifesto, which articulated the long-term vision and initiated the development effort that became
+PowerShell. PowerShell has delivered on many of the elements described in this document.
