+\section{Introduction}
+Thank you for purchasing the openCom LTE from Liberated Embedded
+Systems.
+
+Within your package you will find the following:
+\begin{itemize}
+    \item \textbf{1x openCom LTE}
+    \item LTE antenna(s) (if ordered)
+    \item SMA dust covers (if ordered)
+    \item 3x assorted stickers
+    \item This manual
+\end{itemize}
+
+\newpage
+
+\section{Overview}
+Within this section, we provide an overview of notable aspects of the openCom LTE.
+
+\subsection{Top}
+
+\begin{multicols}{2}
+    The openCom LTE supports 3 antenna connections, with these being:
+    \begin{itemize}
+        \item An SMA main antenna for LTE connectivity (J1)
+        \item An SMA diversity antenna to enhance connection reliability (J2)
+        \item A u.FL GPS antenna for determining location (J3)
+    \end{itemize}
+    The LEDs D2 and D3 are status indicators, and are covered in the next
+    section. 
+
+    \columnbreak
+    \includegraphics[scale=0.27]{top-circled.png}
+\end{multicols}
+Please note that a GPS antenna is \textbf{not included} with the device, and
+one can only be connected with the top cover disassembled.
+
+\subsubsection{LEDs}
+\textbf{D3, or the left LED}, is red, and activates when the device is powered on.
+
+\textbf{D2, or the right LED}, is red, and flashes differently depending on network status:
+\begin{itemize}
+    \item Short flashing - searching for cell tower
+    \item Long flashing - idle
+    \item Quick flicker - data transfer
+    %\item Constantly on - voice calling
+\end{itemize}
+
+
+\subsection{Bottom}
+\begin{multicols}{2}
+    \setlength{\parskip}{0pt} % stop stretching across whole column vertical space
+    On the rear side of the device, the SIM slot is present, which
+    accepts a \textbf{nano sized} SIM card. 
+
+    \vspace{5mm}
+
+    The SIM can be inserted into the slot by pushing it until it clicks. It
+    can also be removed by pushing it until it clicks, and it will spring
+    out after. You may want to consider using the spudger end of your
+    Framework screwdriver to help insert and remove it.
+
+    \vspace{5mm}
+
+    There are many test points present on rear of the device, which are
+    documented in the next section.
+
+    \columnbreak
+    \includegraphics[scale=0.25]{bottom-circled.png}
+\end{multicols}
+
+\newpage
+
+\subsection{Test points}
+\begin{multicols}{2}
+    \setlength{\parskip}{0pt} % stop stretching across whole column vertical space
+    There are several test points available on the device, which allow you to
+    test critical functionality of the device if you so choose.
+
+    These are detailed below:
+    \begin{itemize}
+        \item TP1 - USB D+ trace
+        \item TP2 - USB D- trace
+        \item TP3 - GND
+        \item TP4 - USB\_BOOT
+        \item TP5 - VDD\_EXT
+    \end{itemize}
+
+    Note that to access TP1 and TP2, the resistor pads R13 and R14 must be
+    bridged with wire or solder, as 0Ω resistors are not provided here.
+
+    \subsubsection{Emergency download mode}
+    If necessary, the module can be booted into emergency download mode by
+    shorting TP4 and TP5 before powering it up. This will allow you to upgrade
+    the firmware of the module over USB. The firmware upgrade can only be done with the QFlash utility from Quectel, which only works on Windows. A download link is provided in Section \ref{sec:Windows}.
+
+    \columnbreak
+    \includegraphics[scale=0.25]{test-points-circled.png}
+\end{multicols}
+
+\newpage
+
+\section{Installation}
+\begin{multicols}{2}
+    In order to use your openCom LTE, you must first connect the external
+    antenna(s) to facilitate communication.
+
+    Connect an antenna to the \textbf{J1 port} on the device, which is the
+    right external SMA connector. It is screwed on clockwise.
+
+    Although the diversity antenna on the \textbf{J2 port} is optional,
+    \textbf{consider also connecting it} to the device in order to ensure an
+    optimal internet connection.
+
+
+    \columnbreak
+    \includegraphics[scale=0.2]{sma-circled.png}
+\end{multicols}
+
+Your openCom LTE is now assembled and ready to go, and can be inserted into
+your Framework Laptop by slotting it into an empty Expansion Card bay.
+
+\textbf{Remember to insert your SIM card!}
+
+\newpage
+
+\section{Usage}
+\subsection{Antennas}
+If you chose to bring your own LTE antennas at checkout, please ensure you
+purchase LTE antennas with a VSWR < 2 for optimal performance.
+
+Additionally, if you choose to purchase a GPS antenna for your use, ensure it is a passive antenna (active antennas are not supported), with a VSWR <= 2.
+
+\subsection{Linux}
+On Linux you may use NetworkManager with ModemManager to create a connection
+for your openCom LTE. With the device plugged in, create a new connection,
+choosing "mobile broadband", then progress through the Wizard. If you use
+\textbf{Arch Linux}, there are great wiki articles on the subject.
+
+\subsection{Windows}
+\label{sec:Windows}
+Download the drivers to interface with your openCom LTE from the following
+link: \\
+\texttt{https://link.liberatedsystems.co.uk/EG95} \\
+Within the archive, you will find the executable file to install your drivers.
+
+\newpage
+
+\section{Enclosure}
+\subsection{Disassembly}
+There are two M2 screws on the exterior section of the device which hold on the
+lid. Unscrewing them, you can take the lid off, and the LED columns with it
+(\textbf{don't lose them!}).
+
+There are just two M1 screws holding the circuit board onto the bottom of the
+enclosure, which when removed allow for the removal of the board. However, we
+do not recommend these screws are removed frequently, as their effectiveness
+will decrease over time if they are.
+
+\subsection{Assembly}
+Insert the circuit board into the bottom of the enclosure, and fasten it in
+with the two M1 screws.
+
+Insert the LED columns into their respective holes on the lid (upside down).
+Then, place the bottom part of the enclosure on top of the lid. Finally, insert
+the M2 screws, and screw them into their respective holes on the exterior
+section.
+
+\newpage
+
+\section{AT commands}
+For information concerning the available AT commands, please download the
+archive from the following link: \\
+\texttt{https://link.liberatedsystems.co.uk/EG95} \\
+Within, you will find a copy of the AT command manual for your openCom LTE,
+which utilises Quectel's EG95 module.
+
+\section{Durability}
+Please be careful of the conditions in which you use this device, do not expose
+it to rain or submerge it in bodies of water.
+
+
