             Please translate the README source file to {targetLanguage}. \
               Make the translation sound as natural as possible. \
-              Make sure that {targetLanguage} is linked to the corresponding README file using its Language Culture Name. \
-              Keep the HTML snippet in the same place as in the source file or add it at the top and keep existing languages. \
-              For example, for English, Chinese and German the top of the README should look like this:
+              Keep the HTML snippet in the same place as in the source file or add it below the top heading and keep existing languages. \
+              {targetLanguage} should be shown in plaintext and other languages as links to the corresponding README files using the Language Culture Name. \
+              For example, for English, Chinese and German the top of the German README should look like this:
               <p align="center">
                 <a href="README.md">English</a> |
                 <a href="README.zh-CN.md">简体中文</a> |
-                <a href="README.de-DE.md">Deutsch</a>
+                <span>Deutsch</span>
               </p>
               Do NOT add ``` tags to the HTML snippet.
