[Exclusivity groups](../experiments/exclusive-experiments) ensure that experiments don't overlap, so no user is in multiple experiments at the same time.

## Create an Exclusivity Group

If you don't already have an exclusivity group, create one first:

<Steps>
  <Step title="Go to Surfaces on the left sidebar" />

  <Step title="Select the surface" />

  <Step title="Select Settings" />

  <Step title="Select Add exclusivity group" />

  <Step title="Configure the exclusivity group">
    Give it a name and description. Choose whether it should be marked as suggested, which means it will be automatically pre-selected for experiments on the surface.
  </Step>
</Steps>

## Make an Experiment Exclusive

<Steps>
  <Step title="Go to the experiment">
    Go to Confidence and find the A/B test or rollout you want to make mutually exclusive with other experiments.
  </Step>

  <Step title="Select the surface">
    Select the surface on which the exclusivity group lives.
  </Step>

  <Step title="Select the exclusivity group">
    Select the exclusivity group you want to use.
  </Step>

  <Step title="Click Save" />
</Steps>

The experiment is now mutually exclusive with other experiments that share the same exclusivity group.
