“You’d better ~” means “it would be better to ~,” and it carries a stronger nuance of recommendation or warning than a simple suggestion.
It is especially often used in meetings, academic conferences, and similar settings when you want to avoid mistakes or emphasize important preparation. Since it is a contraction of “had better,” it is also generally acceptable in formal situations.
When using it, add the base form of the verb afterward.
