Think of how when the moon is in the sky at night the ground on Earth is lit up and not fully black. Same with the moon, it’s not totally dark on the night side of the moon if the Earth is in the sky from the moon’s perspective.
The language says “including” which means these mentioned types of sources and potentially other sources that don’t sound as good written down so are left out.
Inline code was conspicuously missing in the comparison, which is more unwieldy in asciidoc (requires backtic and plus instead of just backtic). That’s probably the markdown feature I use most often.
