+Intro to NWB
+======================================
+
+Neurodata Without Borders (NWB) provides a common self-describing format
+ideal for archiving neurophysiology data and sharing it with colleagues.
+It provides a schema which helps neuroscientists package their data and
+metadata together so that they are both machine- and human-readable, and
+reusable to gain additional scientific insights. Converting to NWB is
+also a critical step for getting your neurophysiology data in the the
+DANDI archive, and allows you to access a number of powerful analysis
+and visualization tools. The software tools for creating NWB files are
+spread across :ref:`several different tools and repositories<tools-glossary>`.
+
+We understand converting to NWB can be daunting. This guide will walk
+you through the tools available to help you convert your neurophysiology
+data to NWB. We will start with an overview of NWB and the Python and
+MATLAB APIs maintained by the core development team, then discuss
+automated tools for converting formats.
