-# 翻译建议
+   > Note:
+   >
+   > If you installed DocC by downloading a toolchain from Swift.org,
+   > `docc` is located in `usr/bin/`,
+   > relative to the installation path of the toolchain.
+   > Make sure your shell's `PATH` environment variable
+   > includes that directory.
+   >
+   > If you installed DocC by downloading Xcode,
+   > run `xcrun docc preview swift-6-beta-translation.docc` instead.
 
-如果你有兴趣参与项目，请仔细阅读说明：
+3. Replace the content of the original Markdown file with your Chinese translation, following the terminology table below and the [SwiftGG style guide][swiftgg-style-guide]. Submit your translation through a Pull Request. Once verified by SwiftGG members, it will be merged into the current translation branch.
