A run through the basic features to compliment the hands-on seminar. Suitable for a workshop/seminar or as a stand alone practice file, intending to get the audience up to speed and ready to venture out on their own.
The tutorial template for this seminar can be found here.

\section{Highlighting and footnotes}
You can make words \textbf{bold}, \textit{italicise} them, \underline{underline words} or \textbf{make them \emph{stand out} regardless of the surrounding}. You can break a line\\ mid sentence and make footnotes like this \footnote{a footnote}.

\subsection{As part of text}
In total 85 distinct galaxies were identified in the Hubble Deep Field image provided, the list of which can be found in Appendix B at the end of this report. Poisson statistics states that the error in the number of galaxies counted ($N_x$) is simply the root of the count ($\sqrt{N_x}$), this can be represented as a percentage by the following equation, $N_x^2 + N^2$.
\subsection{In the middle, not numbered}
$$ \alpha \beta \times \frac{2G}{x^2B_n}$$
$$ \frac{-b \pm \sqrt{b^2-4ac}}{2a} + \sin{x}$$
% mag = 5 * np.log10(dlpc/10) + M
$$ \mathrm{mag} = 5 \times \mathrm{log}_{10}\left(\frac{D_{l}}{10}\right) + \mathrm{M_{corr}}$$
\subsubsection{And in the middle, numbered}
\begin{equation}
A=bx+24\times F_x
\label{eq:lovely formula}
\end{equation}
\section{Adding images}
Hello, here is some text without a meaning. This text should show what a printed text will look like at this place. If you read this text, you will get no information. Really? Is there no information? Is there.
\subsection{Lonely image}
\begin{figure}[h!]
\centering % keeps the image in the centre
\includegraphics[width=0.5\textwidth]{snailfrog.png}
\caption{A visualisation of a frog.}
\label{fig:frog}
\end{figure}
\lipsum[7]
\subsubsection{Images side by side}
\begin{figure}[h]
\centering
\begin{minipage}{0.45\textwidth}
\centering
\includegraphics[width=0.9\textwidth]{frog.jpg}
\caption{first figure}
\end{minipage}\hfill
\begin{minipage}{0.45\textwidth}
\centering
\includegraphics[width=0.9\textwidth]{serious_frog.jpeg}
\caption{second figure}
\end{minipage}
\end{figure}
\section{Citing and referencing}
\subsection{Referencing figures and equations}
Expression $4\times 3=G\times x$ naturally follows from Eq \ref{eq:lovely formula}, and both of these things have a lot to do with Fig \ref{fig:frog in multicol}.
\subsection{Citing a paper}
This statement has a citation at the end of it \cite{toadetal1958}, and this one has two \cite{toadetal1958, squeaker1982}. A citation with parenthesis is sure to follow \citep{siddiqi2004interspecific}.
\section{Tables}
\begin{table}[ht]
\centering % used for centering table
\begin{tabular}{c c c c} % centered columns (4 columns)
Case & Ar & H & He \\ [0.5ex] % inserts table %heading
\hline % inserts 1 horizontal line

2 & 47 & 877 & 230 \\
3 & 31 & 25 & 415 \\
4 & 35 & 144 & 2356 \\
5 & 45 & 300 & 556 \\ [1ex] % [1ex] adds vertical space
\end{tabular}
\caption{Imaginary experiment results.}
\label{table:nonlin} % is used to refer this table in the text
