Pages: 12 (including cover and credits). Sizes: A4 (210 × 297 mm) and US Letter (8.5 × 11 in), both PDFs included in one zip.

Printing: Print at 100% / actual size on A4 or US Letter, so nothing gets squashed. Inside pages use light backgrounds and print well in black and white; covers are dark, so start from page 2 to save ink.
