 ### Configurations
 
-The Xcode project contains two configurations, which have independent `xcconfig` configuration files, and can run on your local at the same time without conflicts.

+- `Vite`: for vite real-time development.
 
-- `Debug`: No developer account is required, that is `Sign to Run Locally` by default, which will speed up the build during development. This is convenient for developers without an account, and contributors who only need to do simple local debugging.
+- `Debug`: for development and debugging.
 
-- `Release`: A developer account is required, which means it can be used for distribution as well as running on real iOS/iPadOS devices. You will need to override your developer account information in `xcconfig` to complete the build.

 ### xcconfig
 
 All `xcconfig` files are in the [`/xcode/xcconfig/`](../xcode/xcconfig) directory. Each `.xcconfig` file can be overridden by `.dev.xcconfig` in the same path, they will be ignored by `git`, so you can override any build settings locally.
 
-For example, you can create an `Userscripts-Release.dev.xcconfig` file to override [`Userscripts-Release.xcconfig`](../xcode/xcconfig/Userscripts-Release.xcconfig) and fill in your own developer account information there:
