Hi Karen, "Thus" means, "in this way" or "therefore" "because of this".
I saw this on a book:
Lay the pieces out thus.
Thus it was necessary for me to resign.
"Lay the pieces out in this way - Lay the pieces out like this"
"because of this it was necessary for me to resign" (although I'd use "therefore" not thus).
It's an older word.
Also I'd have said, "Lay the pieces out thusly" - if I was you I would avoid using "thus" until you become more comfortable with the language, stay with the words, "like this", "in this way", "because of".
I hope that helps.
