Analog inputs count?

I’m a bit confused about documentation.

One place it says analogRead is availbale for all A0…A7 pins (
Other place ( shows analogRead only for 3 pins

Which one is true?

analogRead is available for A0 to A7. However, when we map to the Shield Shield, we are highlighting which peripherals line up with the Arduino Uno peripherals (since, if you’re using a Shield, that’s theoretically what you’re most concerned with). However I can see how this could be confusing; thank you for the feedback.
