So you have installed correctly KW and its requirements in the mods folder and are ready to start. Load a previously saved game or start a new one. If you start a new game, do as usual (chose or create your household).

Upon entering live mod, a notification message should appear in the upper right corner of the screen showing information about KW's version.

Click on any Sim to bring the Pie Menu and select Kinky category then Settings. Then click on KinkyWorld to enable the mod. KW's welcome messages should appear after a few seconds.

Set the options according to your preferences (see Settings for more information).
