+# Regenerates the installer logo assets in doc/ from the standardized
+# Node.js logo artwork (https://github.com/openjs-foundation/artwork).
+#
+# The generated images are consumed by:
+#   - tools/msvs/msi/nodemsi/product.wxs           (Windows MSI banner/dialog)
+#   - tools/macos-installer/productbuild/distribution.xml.tmpl
+#                                                  (macOS installer background)
+#
+# The WiX UI bitmap slots are fixed-size (493x58 banner, 493x312 dialog) and
+# the macOS background is placed unscaled (180x361), so the output dimensions
+# must not change. Logo widths and offsets below were measured from the
+# previous assets so the layout stays identical.
+#
+# Prerequisites: rsvg-convert (librsvg), magick (ImageMagick 7), curl
+#
+# Usage: tools/generate-installer-assets.sh
+
+set -e
+
+# Pinned artwork revision so the output is reproducible.
