+# Voice and Tone of openEuler Documentation
+
+The openEuler developer community is built more than just code. Our voice and tone set developers' expectation for the efficient and valuable experiences, resources, and interactions that openEuler provides.    
+
+## Conversational tone  
+
+==Using a lighthearted, friendly tone== and offering specific suggestions for contributions can go a long way in making people feel welcomed and excited to participate in openEuler.   
+
+For example,  
+
+"Hi Judith, welcome to the openEuler Community. I'm the Bot here serving you."  
+
+"First off, thank you for considering contributing to openEuler. It’s people like you that make openEuler such a great community."  
+
+## Inclusive language
+
+==Use simple language==, as many of our readers may not be native English speakers. Therefore,  
+
+- Don't idioms. Use more formal terms that are well defined.  
+
+- Keep things brief, and avoid words and phrases that are vague or confusing.   
+
+==All users and developers are welcomed== in the openEuler community. We're going to have people with diverse backgrounds. Therefore,  
+
+- Don't use any terms that any group may feel offended.  
+- Always use gender-neutral pronouns.  
+- Don't assume people have prior knowledge about openEuler. Provide the basic knowledge needed to better understand openEuler.
