 # pdfpc
 
-This packages allows to define additional meta data within
-the PDF file which can be interpreted by the pdf presenter
-console (pdfpc) program.
+This LaTeX package provides a convenient way to specify notes and to define
+certain meta properties of the presentation when used with [PDF Presenter
+Console (`pdfpc`)](https://pdfpc.github.io), a GPLv3+ licensed multi-monitor PDF
+presentation viewer application available on GitHub.
+
 
 ## Dependencies
 
-`pdfpc` depends on these packages:
+The `pdfpc` package depends on these other packages:
 [`kvoptions`](https://ctan.org/pkg/kvoptions),
 [`xstring`](https://ctan.org/pkg/xstring),
 [`iftex`](https://ctan.org/pkg/iftex),
 [`hyperxmp`](https://ctan.org/pkg/hyperxmp)
 
+When using LuaTeX, it additionally depends on these packages:
+[`stringenc`](https://ctan.org/pkg/stringenc),
+[`pdftexcmds`](https://ctan.org/pkg/pdftexcmds)
+
+
 ## Usage
 
-It's best to read the [`pdfpc`](https://github.com/pdfpc/pdfpc) documentation
-for `pdfpc` integration.
+The [PDF Presenter Console](https://pdfpc.github.io) program accepts a variety
+of configuration options when started from the command line. (See the *pdfpc(1)*
+manual page for details.)
+
+This package allows certain details, such as presentation duration, default
+slide transitions, and speaker notes, to be specified within the metadata of the
+PDF itself, instead of via the command line. These settings are parsed by the
+PDF Presenter Console when the presentation is loaded.
+
+These parameters can be specified as package options, or via the `\pdfpcsetup` command.
+
+The following is a simple LaTeX document demonstrating a few example features:
+
+```latex
+\documentclass{beamer}
+\usepackage[overridenote]{pdfpc}
+% "overridenote" must be specified as a package option
+\pdfpcsetup{
+    % Other settings can be package options, or can go here
+    duration=5,
+    lastminutes=2,
+}
+
+% The usual Beamer document setup
+\title{\texttt{pdfpc} Example Presentation}
+\author{\texttt{pdfpc} Contributors}
+\institute{GitHub}
+\date{\today}
+
+\begin{document}
+\maketitle
+
+\begin{frame}
+    Hello PDFPC World!
+    % Because of "overridenote", this uses the pdfpc note command
+    \note{This speaker note will be shown by `pdfpc`, but hidden for the audience.}
+    \pause
+    Notice that the timer starts counting down from 5 minutes, just as we specified in the preamble!
+\end{frame}
+
+\end{document}
+```
+
+
+## Documentation
 
+Complete
+[documentation](http://mirrors.ctan.org/macros/latex/contrib/pdfpc/pdfpc-doc.pdf)
+for the current version of `pdfpc` is availble on [its CTAN

 \section*{Loading \sty{pdfpc}}
 
-Load \sty{pdfpc} by adding \cmd{\usepackage[\param{options}]\{pdfpc\}} to your
-preamble.
-
+Load \sty{pdfpc} by adding \cmd{\usepackage[\param{options}]\{pdfpc\}} to your preamble.
 The following options may be given as comma-separated list:
 
-\begin{itemize}
-\item \texttt{duration}
-\item \texttt{starttime}
-\item \texttt{endtime}
-\item \texttt{enduserslide}
-\item \texttt{lastminutes}
-\item \texttt{hidenotes}
-\item \texttt{overridenote}
-\item \texttt{disablemarkdown}
-\item \texttt{defaulttransition} (needs pdfpc v4.5 or higher)
-\end{itemize}
-
-Alternatively, the options can be set using the \cmd{\pdfpcsetup} command
-like \cmd{\pdfpcsetup\{\param{option1=value1}[,~\ldots]\}}.
-The meaning and possible values of most of these options are documented in
-\textit{pdfpcrc(5)} man page of the pdfpc program. The rest are explained below.
-
-To add a note to a slide, use \cmd{\pdfpcnote\{Text of a note\}}. A line break
-in the body of the note can be inserted with \cmd{\\}. The notes are rendered
-according to the Markdown syntax by default. If you prefer the plain text format
-(which was the case with \texttt{pdfpc}-4.4 and below), use the
-\texttt{disablemarkdown} option.
-
-The pdfpc package can be used standalone or together with beamer. In
-the later case, it may be desirable to continue using the \cmd{\note}
-command. To this end, the \texttt{overridenote} option should be provided.
-Please note though, that this will work only in simple cases.
-
-If you prefer using full-featured beamer notes rendered alongside the
-presentation (\cmd{\setbeameroption\{show notes on second screen\}}), the pdfpc
-package will autodetect it, so using the \texttt{--notes} command-line option is
-unnecessary. To override the autodetection, use the \texttt{notesposition}
-option, accepting the same values (right/left/top/bottom/none).
-
-When sharing slides, one may want to omit the (private) notes, by using the
-\texttt{hidenotes} option. Enabling it together with \texttt{overridenote} will
-disable the beamer notes as well.

+Options should be given as a comma-separated list.
+All options, aside from \texttt{overridenote}, can alternatively be set via a command of the form \cmd{\pdfpcsetup\{\param{option1=value1}[,~\ldots]\}}.
+
+The meaning and possible values of most of these options are documented in the \textit{pdfpc(1)} man page, provided by the \texttt{pdfpc} program.
+The rest are explained below.
+
+To add a note to a slide, use \cmd{\pdfpcnote\{Text of a note\}}, which also supports Beamer's overlay specifications\footnote{See sections 3.10 and 9.2 of the \texttt{beamer} package documentation.}.
+A line break in the body of the note can be inserted with \cmd{\\}.
+To preserve a whitespace, e.g., to indent a nested list, preceed it by a backslash.
+The notes are rendered according to the Markdown syntax by default.
+If you prefer the plain text format (which was the case with \texttt{pdfpc}-4.4 and below), use the \texttt{disablemarkdown} option.
+
+The pdfpc package can be used standalone or together with Beamer.
+In the later case, it may be desirable to continue using the \cmd{\note} command.
+To this end, the \texttt{overridenote} option should be provided.
+Note, however, that this will work only in simple cases.
+
+If you prefer full-featured Beamer notes rendered alongside the presentation (as with \cmd{\setbeameroption\{show notes on second screen\}}), the pdfpc package will autodetect this, so using the \texttt{--notes} command-line option is unnecessary.
+To override the autodetection, use the \texttt{notesposition} option, accepting the same values (right/left/top/bottom/none) that Beamer natively supports.
+
+When sharing slides, one may want to omit the (potentially private) notes, by using the \texttt{hidenotes} option.
+Enabling it will disable notes, including Beamer notes if \texttt{overridenote} was specified.
+
+Finally, be aware that some features are unsupported by old versions of the \texttt{pdfpc} console.
+In particular, the \texttt{defaulttransition} option requires version 4.5 or later.
