+\section{Introduction}
+ACM's consolidated article template, introduced in 2017, provides a
+consistent \LaTeX\ style for use across ACM publications, and
+incorporates accessibility and metadata-extraction functionality
+necessary for future Digital Library endeavors. Numerous ACM and
+SIG-specific \LaTeX\ templates have been examined, and their unique
+features incorporated into this single new template.
+
+If you are new to publishing with ACM, this document is a valuable
+guide to the process of preparing your work for publication. If you
+have published with ACM before, this document provides insight and
+instruction into more recent changes to the article template.
+
+The ``\verb|acmart|'' document class can be used to prepare articles
+for any ACM publication --- conference or journal, and for any stage
+of publication, from review to final ``camera-ready'' copy, to the
+author's own version, with {\itshape very} few changes to the source.
+
+\section{Template Overview}
+As noted in the introduction, the ``\verb|acmart|'' document class can
+be used to prepare many different kinds of documentation --- a
+double-blind initial submission of a full-length technical paper, a
+two-page SIGGRAPH Emerging Technologies abstract, a ``camera-ready''
+journal article, a SIGCHI Extended Abstract, and more --- all by
+selecting the appropriate {\itshape template style} and {\itshape
+  template parameters}.
+
+This document will explain the major features of the document
+class. For further information, the {\itshape \LaTeX\ User's Guide} is
+available from
+\url{https://www.acm.org/publications/proceedings-template}.
+
+\subsection{Template Styles}
+
+The primary parameter given to the ``\verb|acmart|'' document class is
+the {\itshape template style} which corresponds to the kind of publication
+or SIG publishing the work. This parameter is enclosed in square
+brackets and is a part of the {\verb|documentclass|} command:
+\begin{verbatim}
+  \documentclass[STYLE]{acmart}
+\end{verbatim}
+
+Journals use one of three template styles. All but three ACM journals
+use the {\verb|acmsmall|} template style:
+\begin{itemize}
+\item {\verb|acmsmall|}: The default journal template style.
+\item {\verb|acmlarge|}: Used by JOCCH and TAP.
+\item {\verb|acmtog|}: Used by TOG.
+\end{itemize}
+
+The majority of conference proceedings documentation will use the {\verb|acmconf|} template style.
+\begin{itemize}
+\item {\verb|acmconf|}: The default proceedings template style.
+\item{\verb|sigchi|}: Used for SIGCHI conference articles.
+\item{\verb|sigchi-a|}: Used for SIGCHI ``Extended Abstract'' articles.
+\item{\verb|sigplan|}: Used for SIGPLAN conference articles.
+\end{itemize}
+
+\subsection{Template Parameters}
+
+In addition to specifying the {\itshape template style} to be used in
+formatting your work, there are a number of {\itshape template parameters}
+which modify some part of the applied template style. A complete list
+of these parameters can be found in the {\itshape \LaTeX\ User's Guide.}
+
+Frequently-used parameters, or combinations of parameters, include:
+\begin{itemize}
+\item {\verb|anonymous,review|}: Suitable for a ``double-blind''
+  conference submission. Anonymizes the work and includes line
+  numbers. Use with the \verb|\acmSubmissionID| command to print the
+  submission's unique ID on each page of the work.
+\item{\verb|authorversion|}: Produces a version of the work suitable
+  for posting by the author.
+\item{\verb|screen|}: Produces colored hyperlinks.
+\end{itemize}
+
+This document uses the following string as the first command in the
+source file:
+\begin{verbatim}
+\documentclass[acmsmall,screen,review]{acmart}
+\end{verbatim}
+
+\section{Modifications}
+
+Modifying the template --- including but not limited to: adjusting
+margins, typeface sizes, line spacing, paragraph and list definitions,
+and the use of the \verb|\vspace| command to manually adjust the
+vertical spacing between elements of your work --- is not allowed.
+
+{\bfseries Your document will be returned to you for revision if
+  modifications are discovered.}
+
+\section{Typefaces}
+
+The ``\verb|acmart|'' document class requires the use of the
+``Libertine'' typeface family. Your \TeX\ installation should include
+this set of packages. Please do not substitute other typefaces. The
+``\verb|lmodern|'' and ``\verb|ltimes|'' packages should not be used,
+as they will override the built-in typeface families.
+
+\section{Title Information}
+
+The title of your work should use capital letters appropriately -
+\url{https://capitalizemytitle.com/} has useful rules for
+capitalization. Use the {\verb|title|} command to define the title of
+your work. If your work has a subtitle, define it with the
+{\verb|subtitle|} command.  Do not insert line breaks in your title.
+
+If your title is lengthy, you must define a short version to be used
+in the page headers, to prevent overlapping text. The \verb|title|
+command has a ``short title'' parameter:
+\begin{verbatim}
+  \title[short title]{full title}
+\end{verbatim}
+
+\section{Authors and Affiliations}
+
+Each author must be defined separately for accurate metadata
+identification. Multiple authors may share one affiliation. Authors'
+names should not be abbreviated; use full first names wherever
+possible. Include authors' e-mail addresses whenever possible.
+
+Grouping authors' names or e-mail addresses, or providing an ``e-mail
+alias,'' as shown below, is not acceptable:
+\begin{verbatim}
+  \author{Brooke Aster, David Mehldau}
+  \email{dave,judy,steve@university.edu}
+  \email{firstname.lastname@phillips.org}
+\end{verbatim}
+
+The \verb|authornote| and \verb|authornotemark| commands allow a note
+to apply to multiple authors --- for example, if the first two authors
+of an article contributed equally to the work.
+
+If your author list is lengthy, you must define a shortened version of
+the list of authors to be used in the page headers, to prevent
+overlapping text. The following command should be placed just after
+the last \verb|\author{}| definition:
+\begin{verbatim}
+  \renewcommand{\shortauthors}{McCartney, et al.}
+\end{verbatim}
+Omitting this command will force the use of a concatenated list of all
+of the authors' names, which may result in overlapping text in the
+page headers.
+
+The article template's documentation, available at
+\url{https://www.acm.org/publications/proceedings-template}, has a
+complete explanation of these commands and tips for their effective
+use.
+
+Note that authors' addresses are mandatory for journal articles.
+
+\section{Rights Information}
+
+Authors of any work published by ACM will need to complete a rights
+form. Depending on the kind of work, and the rights management choice
+made by the author, this may be copyright transfer, permission,
+license, or an OA (open access) agreement.
+
+Regardless of the rights management choice, the author will receive a
+copy of the completed rights form once it has been submitted. This
+form contains \LaTeX\ commands that must be copied into the source
+document. When the document source is compiled, these commands and
+their parameters add formatted text to several areas of the final
+document:
+\begin{itemize}
+\item the ``ACM Reference Format'' text on the first page.
+\item the ``rights management'' text on the first page.
+\item the conference information in the page header(s).
+\end{itemize}
+
+Rights information is unique to the work; if you are preparing several
+works for an event, make sure to use the correct set of commands with
+each of the works.
+
+The ACM Reference Format text is required for all articles over one
+page in length, and is optional for one-page articles (abstracts).
+
+\section{CCS Concepts and User-Defined Keywords}
+
+Two elements of the ``acmart'' document class provide powerful
+taxonomic tools for you to help readers find your work in an online
+search.
+
+The ACM Computing Classification System ---
+\url{https://www.acm.org/publications/class-2012} --- is a set of
+classifiers and concepts that describe the computing
+discipline. Authors can select entries from this classification
+system, via \url{https://dl.acm.org/ccs/ccs.cfm}, and generate the
+commands to be included in the \LaTeX\ source.
+
+User-defined keywords are a comma-separated list of words and phrases
+of the authors' choosing, providing a more flexible way of describing
+the research being presented.
+
+CCS concepts and user-defined keywords are required for for all
+articles over two pages in length, and are optional for one- and
+two-page articles (or abstracts).
+
+\section{Sectioning Commands}
+
+Your work should use standard \LaTeX\ sectioning commands:
+\verb|section|, \verb|subsection|, \verb|subsubsection|, and
+\verb|paragraph|. They should be numbered; do not remove the numbering
+from the commands.
+
+Simulating a sectioning command by setting the first word or words of
+a paragraph in boldface or italicized text is {\bfseries not allowed.}
+
+\section{Tables}
+
+The ``\verb|acmart|'' document class includes the ``\verb|booktabs|''
+package --- \url{https://ctan.org/pkg/booktabs} --- for preparing
+high-quality tables.
+
+Table captions are placed {\itshape above} the table.
+
+Because tables cannot be split across pages, the best placement for
+them is typically the top of the page nearest their initial cite.  To
+ensure this proper ``floating'' placement of tables, use the
+environment \textbf{table} to enclose the table's contents and the
+table caption.  The contents of the table itself must go in the
+\textbf{tabular} environment, to be aligned properly in rows and
+columns, with the desired horizontal and vertical rules.  Again,
+detailed instructions on \textbf{tabular} material are found in the
+\textit{\LaTeX\ User's Guide}.
+
+Immediately following this sentence is the point at which
+Table~\ref{tab:freq} is included in the input file; compare the
+placement of the table here with the table in the printed output of
+this document.
+
+\begin{table}
+  \caption{Frequency of Special Characters}
+  \label{tab:freq}
+  \begin{tabular}{ccl}
+    \toprule
+    Non-English or Math&Frequency&Comments\\
+    \midrule
+    \O & 1 in 1,000& For Swedish names\\
+    $\pi$ & 1 in 5& Common in math\\
+    \$ & 4 in 5 & Used in business\\
+    $\Psi^2_1$ & 1 in 40,000& Unexplained usage\\
+  \bottomrule
+\end{tabular}
+\end{table}
+
+To set a wider table, which takes up the whole width of the page's
+live area, use the environment \textbf{table*} to enclose the table's
+contents and the table caption.  As with a single-column table, this
+wide table will ``float'' to a location deemed more
+desirable. Immediately following this sentence is the point at which
+Table~\ref{tab:commands} is included in the input file; again, it is
+instructive to compare the placement of the table here with the table
+in the printed output of this document.
+
+\begin{table*}
+  \caption{Some Typical Commands}
+  \label{tab:commands}
+  \begin{tabular}{ccl}
+    \toprule
+    Command &A Number & Comments\\
+    \midrule
+    \texttt{{\char'134}author} & 100& Author \\
+    \texttt{{\char'134}table}& 300 & For tables\\
+    \texttt{{\char'134}table*}& 400& For wider tables\\
+    \bottomrule
+  \end{tabular}
+\end{table*}
+
+Always use midrule to separate table header rows from data rows, and
+use it only for this purpose. This enables assistive technologies to
+recognise table headers and support their users in navigating tables
+more easily.
+
+\section{Math Equations}
+You may want to display math equations in three distinct styles:
+inline, numbered or non-numbered display.  Each of the three are
+discussed in the next sections.
+
+\subsection{Inline (In-text) Equations}
+A formula that appears in the running text is called an inline or
+in-text formula.  It is produced by the \textbf{math} environment,
+which can be invoked with the usual
+\texttt{{\char'134}begin\,\ldots{\char'134}end} construction or with
+the short form \texttt{\$\,\ldots\$}. You can use any of the symbols
+and structures, from $\alpha$ to $\omega$, available in
+\LaTeX~\cite{Lamport:LaTeX}; this section will simply show a few
+examples of in-text equations in context. Notice how this equation:
+\begin{math}
+  \lim_{n\rightarrow \infty}x=0
+\end{math},
+set here in in-line math style, looks slightly different when
+set in display style.  (See next section).
+
+\subsection{Display Equations}
+A numbered display equation---one set off by vertical space from the
+text and centered horizontally---is produced by the \textbf{equation}
+environment. An unnumbered display equation is produced by the
+\textbf{displaymath} environment.
+
+Again, in either environment, you can use any of the symbols and
+structures available in \LaTeX\@; this section will just give a couple
+of examples of display equations in context.  First, consider the
+equation, shown as an inline equation above:
+\begin{equation}
+  \lim_{n\rightarrow \infty}x=0
+\end{equation}
+Notice how it is formatted somewhat differently in
+the \textbf{displaymath}
+environment.  Now, we'll enter an unnumbered equation:
+\begin{displaymath}
+  \sum_{i=0}^{\infty} x + 1
+\end{displaymath}
+and follow it with another numbered equation:
+\begin{equation}
+  \sum_{i=0}^{\infty}x_i=\int_{0}^{\pi+2} f
+\end{equation}
+just to demonstrate \LaTeX's able handling of numbering.
+
+\section{Figures}
+
+The ``\verb|figure|'' environment should be used for figures. One or
+more images can be placed within a figure. If your figure contains
+third-party material, you must clearly identify it as such, as shown
+in the example below.
+\begin{figure}[h]
+  \centering
+  \includegraphics[width=\linewidth]{sample-franklin}
+  \caption{1907 Franklin Model D roadster. Photograph by Harris \&
+    Ewing, Inc. [Public domain], via Wikimedia
+    Commons. (\url{https://goo.gl/VLCRBB}).}
+  \Description{A woman and a girl in white dresses sit in an open car.}
+\end{figure}
+
+Your figures should contain a caption which describes the figure to
+the reader.
+
+Figure captions are placed {\itshape below} the figure.
+
+Every figure should also have a figure description unless it is purely
+decorative. These descriptions convey what’s in the image to someone
+who cannot see it. They are also used by search engine crawlers for
+indexing images, and when images cannot be loaded.
+
+A figure description must be unformatted plain text less than 2000
+characters long (including spaces).  {\bfseries Figure descriptions
+  should not repeat the figure caption – their purpose is to capture
+  important information that is not already provided in the caption or
+  the main text of the paper.} For figures that convey important and
+complex new information, a short text description may not be
+adequate. More complex alternative descriptions can be placed in an
+appendix and referenced in a short figure description. For example,
+provide a data table capturing the information in a bar chart, or a
+structured list representing a graph.  For additional information
+regarding how best to write figure descriptions and why doing this is
+so important, please see
+\url{https://www.acm.org/publications/taps/describing-figures/}.
+
+\subsection{The ``Teaser Figure''}
+
+A ``teaser figure'' is an image, or set of images in one figure, that
+are placed after all author and affiliation information, and before
+the body of the article, spanning the page. If you wish to have such a
+figure in your article, place the command immediately before the
+\verb|\maketitle| command:
+\begin{verbatim}
+  \begin{teaserfigure}
+    \includegraphics[width=\textwidth]{sampleteaser}
+    \caption{figure caption}
+    \Description{figure description}
+  \end{teaserfigure}
+\end{verbatim}
+
+\section{Citations and Bibliographies}
+
+The use of \BibTeX\ for the preparation and formatting of one's
+references is strongly recommended. Authors' names should be complete
+--- use full first names (``Donald E. Knuth'') not initials
+(``D. E. Knuth'') --- and the salient identifying features of a
+reference should be included: title, year, volume, number, pages,
+article DOI, etc.
+
+The bibliography is included in your source document with these two
+commands, placed just before the \verb|\end{document}| command:
+\begin{verbatim}
+  \bibliographystyle{ACM-Reference-Format}
+  \bibliography{bibfile}
+\end{verbatim}
+where ``\verb|bibfile|'' is the name, without the ``\verb|.bib|''
+suffix, of the \BibTeX\ file.
+
+Citations and references are numbered by default. A small number of
+ACM publications have citations and references formatted in the
+``author year'' style; for these exceptions, please include this
+command in the {\bfseries preamble} (before the command
+``\verb|\begin{document}|'') of your \LaTeX\ source:
+\begin{verbatim}
+  \citestyle{acmauthoryear}
+\end{verbatim}
+
+  Some examples.  A paginated journal article \cite{Abril07}, an
+  enumerated journal article \cite{Cohen07}, a reference to an entire
+  issue \cite{JCohen96}, a monograph (whole book) \cite{Kosiur01}, a
+  monograph/whole book in a series (see 2a in spec. document)
+  \cite{Harel79}, a divisible-book such as an anthology or compilation
+  \cite{Editor00} followed by the same example, however we only output
+  the series if the volume number is given \cite{Editor00a} (so
+  Editor00a's series should NOT be present since it has no vol. no.),
+  a chapter in a divisible book \cite{Spector90}, a chapter in a
+  divisible book in a series \cite{Douglass98}, a multi-volume work as
+  book \cite{Knuth97}, a couple of articles in a proceedings (of a
+  conference, symposium, workshop for example) (paginated proceedings
+  article) \cite{Andler79, Hagerup1993}, a proceedings article with
+  all possible elements \cite{Smith10}, an example of an enumerated
+  proceedings article \cite{VanGundy07}, an informally published work
+  \cite{Harel78}, a couple of preprints \cite{Bornmann2019,
+    AnzarootPBM14}, a doctoral dissertation \cite{Clarkson85}, a
+  master's thesis: \cite{anisi03}, an online document / world wide web
+  resource \cite{Thornburg01, Ablamowicz07, Poker06}, a video game
+  (Case 1) \cite{Obama08} and (Case 2) \cite{Novak03} and \cite{Lee05}
+  and (Case 3) a patent \cite{JoeScientist001}, work accepted for
+  publication \cite{rous08}, 'YYYYb'-test for prolific author
+  \cite{SaeediMEJ10} and \cite{SaeediJETC10}. Other cites might
+  contain 'duplicate' DOI and URLs (some SIAM articles)
+  \cite{Kirschmer:2010:AEI:1958016.1958018}. Boris / Barbara Beeton:
+  multi-volume works as books \cite{MR781536} and \cite{MR781537}. A
+  couple of citations with DOIs:
+  \cite{2004:ITE:1009386.1010128,Kirschmer:2010:AEI:1958016.1958018}. Online
+  citations: \cite{TUGInstmem, Thornburg01, CTANacmart}. Artifacts:
+  \cite{R} and \cite{UMassCitations}.
+
+\section{Acknowledgments}
+
+Identification of funding sources and other support, and thanks to
+individuals and groups that assisted in the research and the
+preparation of the work should be included in an acknowledgment
+section, which is placed just before the reference section in your
+document.
+
+This section has a special environment:
+\begin{verbatim}
+  \begin{acks}
+  ...
+  \end{acks}
+\end{verbatim}
+so that the information contained therein can be more easily collected
+during the article metadata extraction phase, and to ensure
+consistency in the spelling of the section heading.
+
+Authors should not prepare this section as a numbered or unnumbered {\verb|\section|}; please use the ``{\verb|acks|}'' environment.
+
+\section{Appendices}
+
+If your work needs an appendix, add it before the
+``\verb|\end{document}|'' command at the conclusion of your source
+document.
+
+Start the appendix with the ``\verb|appendix|'' command:
+\begin{verbatim}
+  \appendix
+\end{verbatim}
+and note that in the appendix, sections are lettered, not
+numbered. This document has two appendices, demonstrating the section
+and subsection identification method.
+
+\section{SIGCHI Extended Abstracts}
+
+The ``\verb|sigchi-a|'' template style (available only in \LaTeX\ and
+not in Word) produces a landscape-orientation formatted article, with
+a wide left margin. Three environments are available for use with the
+``\verb|sigchi-a|'' template style, and produce formatted output in
+the margin:
+\begin{itemize}
+\item {\verb|sidebar|}:  Place formatted text in the margin.
+\item {\verb|marginfigure|}: Place a figure in the margin.
+\item {\verb|margintable|}: Place a table in the margin.
+\end{itemize}
+
+%%
+%% The acknowledgments section is defined using the "acks" environment
+%% (and NOT an unnumbered section). This ensures the proper
+%% identification of the section in the article metadata, and the
+%% consistent spelling of the heading.
+\begin{acks}
+To Robert, for the bagels and explaining CMYK and color spaces.
+\end{acks}
+
+%%
+%% The next two lines define the bibliography style to be used, and
+%% the bibliography file.
+\bibliographystyle{ACM-Reference-Format}
+\bibliography{sample-base}
+
+%%
+%% If your work has an appendix, this is the place to put it.
