The channel lists follow the JSON Schema from schema.json, also available in Markdown format in schema.md.
The channel logos are in the logos/
folder. In the root of a country's folder you'll find the high quality logos, in the highest resolution available, in PNG and SVG format.
Inside of a country's folder you'll also find the optimized/
folder, which contains transformed and optimized versions of the logos in WEBP and SVG format, automatically generated by the optimize-images GitHub Action. The Action transforms logos in PNG format to WEBP and resizes them to have a width of 300px, while the SVG ones just get compressed.
Because the optimization is automatically done by the Action, when you open a pull request and add a logo, don't worry about optimizing or compressing it. Upload the highest quality version you can.
