 ### Installing the client library
 
-    npm install --save text-to-speech
+    npm install --save @google-cloud/text-to-speech
 
+### Using the client library
 
+```javascript
+const fs = require('fs');
+
+// Imports the Google Cloud client library
+const textToSpeech = require('@google-cloud/text-to-speech');
+
+// Creates a client
+const client = new textToSpeech.TextToSpeechClient();
+
+// The text to synthesize
+const text = 'Hello, world!';
+
+// Construct the request
+const request = {
+  input: { text: text },
+  // Select the language and SSML Voice Gender (optional)
+  voice: { languageCode: 'en-US', ssmlGender: 'NEUTRAL' },
+  // Select the type of audio encoding
+  audioConfig: { audioEncoding: 'MP3' }
+};
+
+// Performs the Text-to-Speech request
+client.synthesizeSpeech(request)
