で, where an action happens and how

The pattern

[Place] de [verb] / [Means] de

で marks the place an action occurs, and the tool, vehicle or language used to do it.

The mistake to avoid

に marks where something exists, で marks where something happens. 公園にいます is being in the park; 公園で遊びます is playing in it.
