-Synchronous [Readline.question](http://nodejs.org/api/readline.html#readline_rl_question_query_callback) for interactively running.
+Synchronous [Readline](http://nodejs.org/api/readline.html) for interactively running.  
+The interface is used with process.stdin and process.stdout in order to accept user input.
 
 ## Example
 
 ```js
 var readlineSync = require('readline-sync');
-
-var answer = readlineSync('What is your favorite food? :');
+var answer = readlineSync.question('What is your favorite food? :');
 console.log('Oh, so your favorite food is ' + answer);
 ```

 ## Usage
 
+### setPrompt
+
 ```js
-answer = readlineSync([prompt[, encoding]])
+readlineSync.setPrompt(prompt)
 ```
 
-`require('readline-sync')` returns a Function. Displays the `prompt` to the user if it is given, and then returns the user's response after it has been typed.  
-`encoding` specify encoding method of input (user's response) and output (`prompt`). Defaults to 'utf8'.
+Sets the prompt, for example when you run `node` on the command line, you see `> `, which is node's prompt.
+
+### prompt
+
+```js
+line = readlineSync.prompt()
+```
+
+Readies readline for input from the user, putting the current `setPrompt` options on a new line, giving the user a new spot to write.
+
+### question
+
+```js
+line = readlineSync.question(query)
+```
+
+Displays the `query` to the user, and then returns the user's response after it has been typed.
+
+### setEncoding
+
+```js
+readlineSync.setPrompt(encoding)
+```
+
+Set the encoding method of input (user's response) and output (`prompt`). Defaults to 'utf8'.
