This repository appears at \url{https://github.com/uw-madison-chem-shops/wisconsin-photoreactor}.
This repository contains everything including the source for this very document.
+The Wisconsin Photo-Reactor (WPR) is made to be easily assembled.
+This document is meant to help chemists accomplish this assembly.
+Each reactor has two major components requiring detailed custom assembly:
+
+\begin{itemize}
+ \item The 3D printed enclosure, described in section TODO
+ \item The drive electronics, described in section TODO
+\end{itemize}
+
+With these two major components complete, assembly of the WPR is relatively straight-forward.
+Details of final assembly are described in section TODO.
+
+TODO: THIS IS A LIVING DOCUMENT, PLEASE CONTRIBUTE.
+
\section{3D Printed Enclosure}
\includegraphics[width=\textwidth]{"./3dp-coverat.jpg"}
+The body of the WPR is made up of three main pieces.
+
+\begin{itemize}
+ \item Base, containing LEDs, fan, and drive electronics.
+ \item Top plate accepting reaction vials.
+ \item Walls spacing the top plate at the appropriate distance away from the base.
+\end{itemize}
+
+The WPR base is the same for all reactors.
+The top plate and wall height can be adjusted depending on the particular vials desired.
+Look within the repository in the subdirectory ``photoreactor-tops'' to find existing designs of (wall, top) for a number of different vial sizes.
+We encourage you to design your own (wall, top) if none of these suit your application.
+Consider adding your new designs to repository so that others may benefit from your design efforts.
+In addition to these three main components you should also print a cable-anchor for each of your WPR bases.
+
+TODO: SHARE DETAILS ABOUT CAD SOFTWARE.
+TODO: MAKE IT CLEAR THAT STL FILES ARE THE RELEVANT EXCHANGE FILE.
+TODO: RECOMMEND STL VIEWER.
+TODO: RECOMMEND SLICER.
+
+There are many options for getting your enclosures printed.
+TODO: DO WE WANT TO GIVE ANY ADVICE ABOUT MATERIAL CHOICE?
+TODO: RECOMMEND SPECIFIC MANUFACTURERS.
+Of course, you may wish to print multiple (wall, top) types to be used interchangeably with one base.
+
+Once your parts are done you may need to remove extra bonding material with a razor blade or exacto-knife.
+The three pieces of your reactor should fit together snugly and securely.

\section{Electronics}
\includegraphics[width=\textwidth]{"./electronics-coverart.jpg"}
+The WPR incorporates small circuit boards controlling the incorporated LED and fan.
+We refer to these small boards as ``drivers''.
+There are two types available: the ``analog-driver'' and ``digital-driver''.
+Refer to the associated directories in the online repository for design files for each of these.
+
+The analog-driver circuit is made to be as simple as possible.
+The circuit accepts DC 12 V through a barrel jack.
+A small knob is used to adjust light intensity.
+Fan speed is not adjustable.
+
+The digital-driver circuit is made to be incorporated into an I$^2$C-based digital control system.
+In addition to power, these boards have 4-pin connectors to carry the I$^2$C serial data.
+More details about this digital control system are in TODO: LINK TO SECTION.
