Your introduction goes here! Some examples of commonly used commands and features are listed below, to help you get started.

If you have a question, please use the help menu in the top right of the screen to get in touch. When your article or pre-print is complete, use the "Submit to PeerJ" button in the topbar to send your files to PeerJ.

PeerJ is an award-winning open access publisher covering the biological and medical sciences. PeerJ provides authors with three publication venues: *PeerJ* and *PeerJ Computer Science* (peer-reviewed academic journals) and *PeerJ PrePrints* (a 'pre-print server'). See https://peerj.com/about/publications/ for more information.

The PeerJ model allows an author to publish articles in their peer-reviewed journal via the purchase of a lifetime Publication Plan. Prices start from just \$99 (a one-off payment) which entitles an author to the lifetime ability to publish 1 article per year for free. Publication in PeerJ PrePrints is entirely free.

Use section and subsection commands to organize your document. \LaTeX{} handles all the formatting and numbering automatically. Use ref and label commands for cross-references.

Use the table and tabular commands for basic tables --- see Table \@ref(tab:widgets), for example. You can upload a figure (JPEG, PNG or PDF) using the project menu. To include it in your document, use the includegraphics command as in the code for Figure \@ref(fig:view) below.

Standard \LaTeX references will work as well (e.g. Fig. \ref{fig:view}).

LaTeX formats citations and references automatically using the bibliography records in your .bib file, which you can edit via the project menu. Use the cite command for an inline citation, like @Figueredo:2009dg, and the citep command for a citation in parentheses [@Figueredo:2009dg].

\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 $\mathcal{N}(0, \sigma^2)$.

You can make lists with automatic numbering \dots

We hope you find write\LaTeX\ useful for your PeerJ submission, and please let us know if you have any feedback. Further examples with dummy text are included in the following pages.

This is an equation inserted using LaTeX syntax directly.

\begin{equation} \cos^3 \theta =\frac{1}{4}\cos\theta+\frac{3}{4}\cos 3\theta \label{eq:refname2} \end{equation}

You can also use `$$..$$`

to achieve the same

$$ \cos^3 \theta =\frac{1}{4}\cos\theta+\frac{3}{4}\cos 3\theta $$

Use `{-}`

after a header section so that it is unnumbered.

Header level 4 are equivalent to `\paragraph{}`

You can insert figure using R code chunk with different options

time = seq(1.5, 8, 0.1) plot(time, sin(time), type = "l", xlab = "time [s]", ylab = "amplitude [m]", cex.main = 2, col = "blue", lwd = 3, font = 2, font.main = 2)

You can reference figure if you use **bookdown** format extensions as shown in YAML header

This is another section

Which shows level 2

And level 3 headers

with multiple subsubsections

and subsections

So long and thanks for all the fish.
