+
+We could do something fancy like a NixOS flake, but for the EmacsSurvey server I
+think a simple Debian machine with a setup script should do the trick. Let's
+just work out a setup script to get everything up and running.
+
+The idea is that this repository can be cloned/updated anywhere on the machine
+and =sudo setup.sh= will do the rest.
+
+* Installing software
+** Caddy web server
+
+#+begin_src sh
+if ! rpm -q caddy > /dev/null; then
+    echo -e "\e[1;34mInstalling Caddy\e[m"
+    # Taken from <https://caddyserver.com/docs/install#debian-ubuntu-raspbian>
+    sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https
+    curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
+    curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
+    sudo apt update
+    sudo apt install caddy
+fi
+#+end_src
+
+** Julia
+
+First, we specify the Julia version we want and hope that the relevant paths
+continue to be predictable.
+
+#+begin_src sh
+JULIA_VERSION="1.8.2"
+#+end_src
+
+If either the =julia= command does not exist, or =julia --version= does not match
+the expected output, then we will install Julia in =/opt/julia= and symlink the
+binary into =/usr/bin=.
+
+#+begin_src sh
+if ! command -v julia > /dev/null || [ ! $(julia --version) = "julia version $JULIA_VERSION" ]; then
+    echo -e "\e[1;34mInstalling Julia\e[m"
+    pushd /tmp > /dev/null
+    # Following <https://julialang.org/downloads/platform/>
+    wget "https://julialang-s3.julialang.org/bin/linux/x64/${JULIA_VERSION%.*}/julia-$JULIA_VERSION-linux-x86_64.tar.gz"
+    mkdir -p "/opt/julia/"
+    tar zxvf "julia-$JULIA_VERSION-linux-x86_64.tar.gz" --directory=/opt/julia
+    ln -sf "/opt/julia/julia-$JULIA_VERSION/bin/julia" /usr/bin/julia
+fi
+#+end_src
+
+* Copying over relevant files
+
+Before starting to do this, we will obtain the path to the folder of the script,
+so we can grab files relative to the root of this repository.
+
+#+begin_src sh
+SETUPDIR=$(dirname "$(readlink --canonicalize-existing "$0")")
+#+end_src
+
+** Caddy Config
+
+#+begin_src sh
+cp -f "$SETUPDIR/Caddyfile" "/etc/caddy/Caddyfile"
+#+end_src
+
+* Ensuring services are running
