 Abstract
 --------
 
-Whilst the TeX family of programs is widely used in the sciences
-and academia overall, there seems to be a lack of support for
-the humanities, which commonly adhere to MLA format for
-student papers and reports.
-
-Though there *are*
-[MLA-style packages available](https://ctan.org/pkg/mla-paper),
-none met the expectations of the author (who was mostly
-just nit-picky about elegance in code).
-So *voilà*, there now exists a proper `mla.cls`:
-a simple, straightforward class for composing papers
-almost perfectly adherent to the
-[MLA style guide](https://style.mla.org/).
+In the United States, secondary and undergraduate students
+are generally expected to adhere to the format prescribed by
+the Modern Language Association (MLA) for typewritten essays,
+research papers and writings.
+Sadly, the tool of choice is usually Microsoft Word,
+even amongst those fluent with TeX.
+
+Though there *are* some templates and tools to aid in writing
+in the MLA format using LaTeX, none fully met the expectations
+of the author.
+So *voilà*, there now exists an `mla.cls` proper:
+a simple, straightforward class for composing papers almost

+\begin{document}

+\begin{paper}
+
+This is an example document using ``mla.cls''.
+The header is automatically printed upon using the ``paper'' class,
+which is why there is no ``\textbackslash{}maketitle''.
+
+\section{Professors who prefer sections}
+
+Sometimes, research papers can become unmanageably lengthy.
+In that case, section headings can help divide up the ideas
+to make it more accessible to the reader.
+Though this paper is short, section headings are employed
+as an example of the ``mla'' class' capabilities.
+
+Some professors may explicitly require or denounce use of headings.
+Dr. Suzie Que of Anytown, PA requires they be used for anything
+longer than five pages:
+\begin{blockquote}
+John---so help me God---if you turn in another twenty-page research
+paper with no logical breaks I will hang you at the stake.
+Even though the MLA style guide doesn't say anything about
+section headings, they're not actually prohibited.
+So, if you turn in \emph{anything} longer than five pages to me
+and there isn't a \emph{single} break or section heading,
+I will dock your grade to an F.
+Capisce? \cite{que2019}
+\end{blockquote}
+Despite her language, she does have a point to say.
+
+\subsection{Subsections}
+
+Alongside regular top-level sections, one can use
+``\textbackslash{}subsection'' commands too\endnote{Section commands
+in ``mla.cls'' work identical to those of the ``article'' class.}.
+
+\section{Using endnotes}
+
+As one may notice, the above subsection used an endnote.
+These can simply be cited with
+``Yada yada text\textbackslash{}endnote\{more info\ldots\}.''
+Endnotes can be easily printed in correct format by calling
+``\textbackslash{}printendnotes[mla]'' within the
+``notes'' environment.
+
+\section{Using bibliographies}
+
+Dr. Suzie Que was cited in the above blockquote.
+The ins-and-outs of ``biblatex'' will not be explained in this
+document, so please refer to online documentation such as the
+``BibLaTeX Cheat Sheet''.
+
+Just as with the endnotes,
+the bibliography can be easily printed in correct format by calling
+``\textbackslash{}printbibliography[heading=none]'' within the
+``workscited'' environment.
+(The ``heading=none'' part is important; the ``workscited'' environment
+already prints one.)
