# Setup Parameters They are separated in two groups: [general options](#general-options) (push and view) and [source side](#source-side-options) (push) options. ## General options You can add them to both, source ([`&push`](/advanced-settings/setup-parameters/push.md)) and viewer ([`&view`](/advanced-settings/mixer-scene-parameters/view.md), [`&scene`](/advanced-settings/mixer-scene-parameters/scene.md) or [`&solo`](/advanced-settings/mixer-scene-parameters/and-solo.md)) sides.
