      <p>You have two or more environments and versions of your application, but you do trunk-based development, so you only have a single branch that you use on all environments.</p>

      <p>But if all environments have the same code, how can we have differences between them?</p>

      <p>What if we want a feature enabled on one environment and not the other?</p>

      <h2 id="feature-flags">Feature flags</h2>

      <p>Feature flags are an approach I've previously written about. You have two branches of logic within your code, and the flow changes based on whether a flag is enabled.</p>

      <p>If a flag is enabled, execute the first block of code. Otherwise, execute the second.</p>

      <p>Now, you enable and disable the required feature flags for each environment.</p>

      <p><strong>The code is the same for all environments, but the enabled features and functionality are different.</strong></p>

      <p>Then, once the feature has been deployed and released in production, the feature flag can be removed.</p>
