+
+<Info>
+  If this is your project's first cloud integration, then you'll have to grant Infisical access to your project's environment variables.
+  Although this step breaks E2EE, it's necessary for Infisical to sync the environment variables to the cloud platform.
+</Info>
+
+## Start integration
+
+Select which Infisical environment secrets you want to sync to which BitBucket repo and press start integration to start syncing secrets to the repo.
