Start by saying hello, asking a question or pasting a code.
For example, by writing "Hello!" or "Hei!".
You can also ask questions related to code or programs etc, e.g. "Whats the difference between Vue and React",
"What is a for loop in python",
"Osaatko Suomea?"
You can also ask unrelated questions such as. "Kuka on Mika Rasi?" ATTENTTION! In this case the answer may not strike true.
