+## getpass
+
+Get a password from the terminal. Sounds simple? Sounds like the `readline`
+module should be able to do it? NOPE.
+
+## Install and use it
+
+```bash
+npm install --save getpass
+```
+
+```javascript
+const mod_getpass = require('getpass');
+```
+
+## API
+
+### `mod_getpass.getPass([options, ]callback)`
+
+Gets a password from the terminal. If available, this uses `/dev/tty` to avoid
+interfering with any data being piped in or out of stdio.
+
+This function prints a prompt (by default `Password:`) and then accepts input
+without echoing.
+
+Parameters:
+
+ * `options`, an Object, with properties:
+   * `prompt`, an optional String
+ * `callback`, a `Func(error, password)`, with arguments:
+   * `error`, either `null` (no error) or an `Error` instance
+   * `password`, a String
