About Messages on Installs

Greetings, dear community members,

I sometimes use npm and, in the installation process, some packages throw
messages regarding to warnings or info/survey URLs.

I wish to use something similar in a package I maintain. Is it possible to
print some data to users' terminal in the installation process? Even if so,
would it be considered a good practice?

Many thanks in advance.
