+#!/usr/bin/env bash
+
+# This script automates compressing PNG images using the lossless Zopfli
+# Compression Algorithm. The process is slow but can produce significantly
+# better compression and, thus, smaller file sizes.
+#
+# This script is meant to be run manually, for example, before making a new
+# release.
+#
+# Requirements
+#
+# zopflipng - https://github.com/google/zopfli
+#             Debian/Ubuntu: sudo apt install zopfli
+#             Fedora:        sudo dnf install zopfli
+#             macOS:         brew install zopfli
+#
+# Usage
+#
+# This script takes a single positional argument which is the path where to
+# search for PNG files. By default, the target path is the current working
+# directory. Run from the root of the repository to compress all PNG images. Run
+# from the `frontend` subdirectory to compress all PNG images within that
+# directory. Alternatively, run from any directory and pass an explicit path to
+# `compress-png` to limit the script to that path/directory.
