Gibbs free energy signs

The notes say that when ΔG is positive, the reaction is spontaneous, and non- spontaneous when negative. Shouldn’t it be the other way around?

Hey!
When the the coefficient of Gibbs free energy is negative, the reaction is spontaneous. For some reactions however, the spontaneity of the reaction is also dependent on the temperature.
Hope this helps! :)
