How do I install (anything) on debian: 'apt is unknown instruction' in Dockerfile

If I search: [how to install wget on debian]

I get articles that say:

$sudo apt install wget

So I try to do that in Docker:

FROM debain
apt install wget

and I get this error

You need to add the RUN instruction, like this:

FROM debian
RUN apt install wget
