## Pyanodon branding

`py-logo.png` is the unmodified thumbnail from the official [Pyanodons Modpack repository](https://github.com/pyanodon/pymodpack/blob/HEAD/thumbnail.png), retrieved 2026-11-03. Artwork © Pyanodon. Licensed under [CC BY-NC-ND 4.0](https://creativecommons.org/licenses/by-nc-nd/4.0/), as stated on the [official mod page](https://mods.factorio.com/mod/pymodpack). This is an unofficial community recipe guide, not an official pY site.

## Inventory icons

`production-icons.webp` comes from the FactorioLab full-pY dataset. Upstream notices are retained in `source-data/licenses/`.

## Installed building previews

`buildings/installed/` contains 709 static building previews from the installed Factorio 2.1.24 and Pyanodon graphics packs. Pyanodon artwork © Pyanodon, CC BY-NC-ND 4.0; vanilla artwork © Wube Software. These previews select the north-facing first frame and assemble prototype layers with their defined positions, scales and tints, omitting glow and shadow layers. They are not screenshots. Game and mod versions, source sprite paths, extraction definitions and the 14 unavailable hidden prototypes are listed in [installed provenance](buildings/installed/provenance.json). Each building dialog also credits and links its source. The installed artwork version is independent of the recipe dataset version.

## Archived building previews

Images labelled **Archived artwork** are actual building sprite sheets from Pyanodons Coal Processing 1.5.5, Factorio 0.17. They are not exported from the current installed game. Current buildings may differ, especially the high pressure furnace. Original image bytes are preserved; SVG viewports display the first frame without modifying the source files.
