+\section{Purpose}
+This activity uses a Docker container with TeX Live to compile a simple LaTeX
+document in a repeatable environment. The work was performed on the group's
+DigitalOcean Droplet.
+
+\section{Project Files}
+The demonstration used two files in the
+\texttt{/root/latex-docker-demo} directory:
+
+\begin{itemize}
+\item \texttt{Dockerfile} defines the TeX Live container image.
+\item \texttt{hello.tex} contains the sample LaTeX document.
+\end{itemize}
+
+\section{Dockerfile}
+The following Dockerfile starts with Ubuntu, installs the TeX Live LaTeX
+package, and sets \texttt{pdflatex} as the container's default command.
+
+\begin{minted}[fontsize=\small,breaklines,frame=single]{dockerfile}
+FROM ubuntu:24.04
+
+RUN apt-get update \
+    && DEBIAN_FRONTEND=noninteractive apt-get install -y \
+       --no-install-recommends texlive-latex-base \
+    && rm -rf /var/lib/apt/lists/*
+
+WORKDIR /work
+
+CMD ["pdflatex", "-interaction=nonstopmode", "-halt-on-error", "hello.tex"]
+\end{minted}
+
+\section{Sample LaTeX Document}
+The following source was saved as \texttt{hello.tex}. It creates a short PDF
+with a title and one sentence.
+
+\begin{minted}[fontsize=\small,breaklines,frame=single,escapeinside=||]{latex}
+|\textbackslash|documentclass[12pt]{article}
+
+\title{LaTeX Docker Demonstration}
+\author{SSW 590 Group 02}
+\date{\today}
+
+\begin{document}
+\maketitle
+
+This PDF was compiled by TeX Live inside a Docker container.
+
+\end{document}
+\end{minted}
+
+\section{Building the Docker Image}
+At the Droplet prompt, the following commands selected the demonstration
+directory and built the image:
+
+\begin{minted}[fontsize=\small,breaklines,frame=single]{bash}
+cd /root/latex-docker-demo
+docker build -t ssw590-latex-demo .
+\end{minted}
+
+\section{Compiling the LaTeX Document}
+The image was run as a temporary container. A bind mount saved the generated
+files in the Droplet directory, where they remained after the container
+stopped.
+
+\begin{minted}[fontsize=\small,breaklines,frame=single]{bash}
+docker run --rm \
+  --mount type=bind,source="$PWD",target=/work \
+  ssw590-latex-demo
+
+ls -lh hello.pdf
+\end{minted}
+
+\section{Results}
+The container ran the LaTeX compiler and reported that its transcript was
+written to \texttt{hello.log}. The file check showed \texttt{hello.pdf} in
+the demonstration directory with a size of approximately 27 KB. This
+confirmed that the sample document was compiled into a PDF on the Droplet.
+
+\section{Cleanup}
+The \texttt{--rm} option removed the container after it stopped. The image
+and demonstration files were retained. If the image is no longer needed,
+it can be removed with:
+
+\begin{minted}[fontsize=\small,breaklines,frame=single]{bash}
+docker image rm ssw590-latex-demo
+\end{minted}
