+# Rock iOS Bitrise Step
+
+This Bitrise step enables remote building of iOS applications using [Rock](https://rockjs.dev). It supports both simulator and device builds, with automatic artifact caching. Code signing should be configured separately in your workflow before using this step.
+
+> [!NOTE]
+> **Code Signing Required**: This step assumes that iOS code signing is already configured in your workflow before using this step. For device builds and re-signing, certificates and provisioning profiles must be available in the keychain. See the [Bitrise iOS Code Signing documentation](https://docs.bitrise.io/en/bitrise-ci/code-signing/ios-code-signing/ios-code-signing.html) for setup instructions.
