Understanding Society User Support

I am doing cross-sectional analysis of wave 3 (adult self completion questionnaire), so I am aware I need to use the weight c_indscub_xw but I don't actually understand how the weight is implemented on STATA. Do I just add c_indscub_xw as if it were an independent variable or is there a command I need to type into stata before doing my analysis in order for the weights to have an effect?

Thanks
