The way to help yourself is as follows.
First you look up what "binding" means in a dictionary.
It means "(Of an agreement or promise) involving an obligation that cannot be broken". That means it is a strict obligation that must be observed.
So, if you have a non-binding agreement, it is not a strict obligation (hence "soft" , or "softer"), which can be ignored.
Now I hope that in future you know how to go about helping yourself by using a dictionary and your own power of analysis.
