  \item Need a little horizontal space? Use \verb|\hphantom{<stuff>}| where \texttt{<stuff>} is any standard unit. (I use this down below to separate the two images with borders when they are on the same line.)

+\subsection{\LaTeX{} Without a GUI}
+
+Despite my blathering on about the benefits of the command line, I'm actually using a GUI editor called Texmaker (which you can find at \href{https://www.xm1math.net/texmaker/}{\texttt{https://www \\ .xm1math.net/texmaker/}}). This seemed the easiest way to learn LaTeX at the time, because all you have to do to get a readable pdf is to press \texttt{F1}.
+
+But you don't need to go that route. You can do this entirely from the command line. Simply create a LaTeX document in any text editor, and save it with a \texttt{.tex} extension. From that point, simply run the following command in a terminal:
+
+\begin{verbatim}
+$ latex file.tex
+\end{verbatim}
+
+This command should generate the following files:
+
+\begin{verbatim}
+file.dvi
+file.aux
+file.log
+\end{verbatim}
+
+\texttt{file.aux} contains information your document needs to manage any cross-references in your document. \texttt{file.log} contains information about how your file was processed; if you run into errors, this is a good place to find a solution, or at least to find what to search the internet for. But it's the \texttt{file.dvi} file that we're interested in.
+
+\texttt{.dvi} files are device independent files. They're a lot like PostScript or PDF, but without font embedding. To convert this to a pdf file, run the following command:
+
+\begin{verbatim}
+$ dvipdf file.dvi
+\end{verbatim}
+
+This should generate \texttt{file.pdf} which you can read in any document viewer. You may need to install \texttt{dvipdf}---on my system (Ubuntu 20.04) it was not installed.
+
+You can also just run \texttt{pdflatex} (which again, you may have to install), which skips over making a \texttt{.dvi} file:
+
+\begin{verbatim}
+$ pdflatex file.tex
+\end{verbatim}
+
+This should generate the following files:
+
+\begin{verbatim}
+file.aux
+file.log
+file.pdf
+\end{verbatim}
+
+I have noticed that when I generate the pdf file using the former method, I get a much smaller file than I do the second time. As an experiment, I ran the \texttt{integral.tex} file I created earlier through both of these methods. Running the file through \texttt{latex} and then through \texttt{dvipdf} resulted in a pdf file that was only 7.0 kb in size. But when I ran it solely through \texttt{pdflatex}, I ended up with a pdf file that was 30.5 kb big. This is most likely due to a difference in compression methods, \footnote{See this for more information: \href{https://tex.stackexchange.com/questions/38145/why-does-pdflatex-produce-bigger-output-files-than-latexdvipdfm}{\texttt{https://tex.stackexchange.com/questions/38145/why-does-pdflatex-produce-bigger-output-files-than-latexdvipdfm}}} so this could make a difference for you if you are working with large documents.
+
+Go forth and manage your mischief.

 \subsection{Custom Page Sizes}
 
 Okay, this is important enough that it deserves its own section.
