\section{Introduction}
Your introduction goes here!
\section{Headings and Subheadings}
\label{sec:examples}
Five levels, numbered automatically.To suppress numbering (e.g., for `Acknowledgements'), use an asterisk before the opening curly brace: \verb|\section*{Acknowledgements}|.
For sub- and superscripts in section titles, use the macros
\verb|\textsubscript| and \verb|\textsuperscript|, respectively.
\begin{enumerate}
\item \verb|\section{...}|
\item \verb|\subsection{...}|
\item \verb|\subsubsection{...}|
\item \verb|\subsubsubsection{...}| (NRC macro)
\item \verb|\paragraph{...}|
\end{enumerate}
\section{Text}
The usual \LaTeX\ commands and environments can be used. Where lists must be flushed to the left margin, there are two NRC-specific environments to use:
\begin{flenumerate}
\item The \verb|flenumerate| environment creates a numbered list with labels flushed to the left margin.
\item Note that no nesting is possible.
\end{flenumerate}
\begin{flitemize}
\item The \verb|flitemize| Generates a bulleted list with labels flushed to the left margin.
\item No nesting possible.
\end{flitemize}
\section{Tables, Figures, Captions}
\subsection{How to Include Figures}
First you have to upload the image file (JPEG, PNG or PDF) from your computer to Overleaf using the upload link the project menu. Then use the includegraphics command to include it in your document. Use the figure environment and the caption command to add a number and a caption to your figure. See the code for Figure \ref{fig:frog} in this section for an example.
\begin{figure}[hbt!]
\centering
%% NRC requires \topcaption to typeset captions at the TOP of floats
\setlength{\captionwidth}{0.3\textwidth}
\topcaption{\label{fig:frog}This frog was uploaded to Overleaf via the project menu.}
\includegraphics[width=0.3\textwidth]{frog.jpg}
\end{figure}
\subsection{How to Make Tables}
Use the table and tabular commands for basic tables --- see Table~\ref{tab:widgets}, for example.
\begin{table}[hbt!]
\centering
%% NRC requires \topcaption to typeset captions at the TOP of floats
\topcaption{\label{tab:widgets}An example table.}
\begin{tabular}{l|r}
\hline* %% Generates thicker lines -- NRC only.
Item of Interest & Quantity \\\hline
Widgets & 42 \\
Gadgets & 13\\
\hline* %% Generates thicker lines -- NRC only.
\end{tabular}
\end{table}
\section{How to Write Mathematics}
\LaTeX{} is great at typesetting mathematics. Let $X_1, X_2, \ldots, X_n$ be a sequence of independent and identically distributed random variables with $\text{E}[X_i] = \mu$ and $\text{Var}[X_i] = \sigma^2 < \infty$, and let
$$S_n = \frac{X_1 + X_2 + \cdots + X_n}{n}
= \frac{1}{n}\sum_{i}^{n} X_i$$
denote their mean. Then as $n$ approaches infinity, the random variables $\sqrt{n}(S_n - \mu)$ converge in distribution to a normal $\mathcal{N}(0, \sigma^2)$.
Equations can be numbered too:
\begin{equation}
S_n = \frac{X_1 + X_2 + \cdots + X_n}{n}
= \frac{1}{n}\sum_{i}^{n} X_i
\end{equation}
\section{Citations and References}
You can use either
\begin{verbatim}
\begin{thebibliography}
\bibitem ...
\end{thebibliography}
\end{verbatim}
%
or \verb|bibtex|. This template uses \texttt{thebibliography}.
Here's a citation:
