Solid logo
The same outline in one color, for single-color print, watermarks, and photos or colored grounds.
App icon
1024×1024 and full-bleed: the system rounds the corners. For app stores and home screens.
README banner
1600×500, exported at twice that resolution, for READMEs and article headers.
Social preview
1280×640, for a GitHub repository's social preview. The mark sits in the middle band, so it stays whole when a topic page crops the image.
