+
+## Goal and Philosophy
+
+**`Inquirer.js`** strives to be an easily embeddable and beautiful command line interface for [Node.js](https://nodejs.org/) (and perhaps the "CLI [Xanadu](https://en.wikipedia.org/wiki/Citizen_Kane)").
+
+**`Inquirer.js`** should ease the process of
+
+- providing _error feedback_
+- _asking questions_
+- _parsing_ input
+- _validating_ answers
+- managing _hierarchical prompts_
+
+> **Note:** **`Inquirer.js`** provides the user interface and the inquiry session flow. If you're searching for a full blown command line program utility, then check out [commander](https://github.com/visionmedia/commander.js), [vorpal](https://github.com/dthree/vorpal) or [args](https://github.com/leo/args).
+
+## [Documentation](#documentation)
+
+
+
+### Installation
+
+
+
+```shell
+npm install inquirer
+```
+
+```javascript
+var inquirer = require('inquirer');
+inquirer
+ .prompt([
+ /* Pass your questions in here */
+ ])
+ .then(answers => {
+ // Use user feedback for... whatever!!
+ });
+```
+
+
+
+### Examples (Run it and see it)
+
+Check out the [`packages/inquirer/examples/`](https://github.com/SBoudrias/Inquirer.js/tree/master/packages/inquirer/examples) folder for code and interface examples.
+
+```shell
+node packages/inquirer/examples/pizza.js
+node packages/inquirer/examples/checkbox.js
+# etc...
+```
+
+### Methods
+
+
+
+#### `inquirer.prompt(questions) -> promise`
+
+Launch the prompt interface (inquiry session)
+
+- **questions** (Array) containing [Question Object](#question) (using the [reactive interface](#reactive-interface), you can also pass a `Rx.Observable` instance)
+- returns a **Promise**
+
+#### `inquirer.registerPrompt(name, prompt)`
+
+Register prompt plugins under `name`.
+
+- **name** (string) name of the this new prompt. (used for question `type`)
+- **prompt** (object) the prompt object itself (the plugin)
+
+#### `inquirer.createPromptModule() -> prompt function`
+
+Create a self contained inquirer module. If you don't want to affect other libraries that also rely on inquirer when you overwrite or add new prompt types.
+
+```js
+var prompt = inquirer.createPromptModule();
+
+prompt(questions).then(/* ... */);
+```
+
+### Objects
+
+
+
+#### Question
+
+
+A question object is a `hash` containing question related values:
+
+- **type**: (String) Type of the prompt. Defaults: `input` - Possible values: `input`, `number`, `confirm`,
+ `list`, `rawlist`, `expand`, `checkbox`, `password`, `editor`
+- **name**: (String) The name to use when storing the answer in the answers hash. If the name contains periods, it will define a path in the answers hash.
+- **message**: (String|Function) The question to print. If defined as a function, the first parameter will be the current inquirer session answers. Defaults to the value of `name` (followed by a colon).
+- **default**: (String|Number|Boolean|Array|Function) Default value(s) to use if nothing is entered, or a function that returns the default value(s). If defined as a function, the first parameter will be the current inquirer session answers.
+- **choices**: (Array|Function) Choices array or a function returning a choices array. If defined as a function, the first parameter will be the current inquirer session answers.
+ Array values can be simple `numbers`, `strings`, or `objects` containing a `name` (to display in list), a `value` (to save in the answers hash) and a `short` (to display after selection) properties. The choices array can also contain [a `Separator`](#separator).
+- **validate**: (Function) Receive the user input and answers hash. Should return `true` if the value is valid, and an error message (`String`) otherwise. If `false` is returned, a default error message is provided.
+- **filter**: (Function) Receive the user input and return the filtered value to be used inside the program. The value returned will be added to the _Answers_ hash.
+- **transformer**: (Function) Receive the user input, answers hash and option flags, and return a transformed value to display to the user. The transformation only impacts what is shown while editing. It does not modify the answers hash.
+- **when**: (Function, Boolean) Receive the current user answers hash and should return `true` or `false` depending on whether or not this question should be asked. The value can also be a simple boolean.
+- **pageSize**: (Number) Change the number of lines that will be rendered when using `list`, `rawList`, `expand` or `checkbox`.
+- **prefix**: (String) Change the default _prefix_ message.
+- **suffix**: (String) Change the default _suffix_ message.
+
+`default`, `choices`(if defined as functions), `validate`, `filter` and `when` functions can be called asynchronously. Either return a promise or use `this.async()` to get a callback you'll call with the final value.
+
+```javascript
+{
+ /* Preferred way: with promise */
+ filter() {
+ return new Promise(/* etc... */);
+ },
+
+ /* Legacy way: with this.async */
+ validate: function (input) {
+ // Declare function as asynchronous, and save the done callback
+ var done = this.async();
+
+ // Do async stuff
+ setTimeout(function() {
+ if (typeof input !== 'number') {
+ // Pass the return value in the done callback
+ done('You need to provide a number');
+ return;
+ }
+ // Pass the return value in the done callback
+ done(null, true);
+ }, 3000);
+ }
+}
+```
+
+### Answers
+
+
+A key/value hash containing the client answers in each prompt.
+
+- **Key** The `name` property of the _question_ object
+- **Value** (Depends on the prompt)
+ - `confirm`: (Boolean)
+ - `input` : User input (filtered if `filter` is defined) (String)
+ - `number`: User input (filtered if `filter` is defined) (Number)
+ - `rawlist`, `list` : Selected choice value (or name if no value specified) (String)
+
+### Separator
+
+
+A separator can be added to any `choices` array:
+
+```
+// In the question object
+choices: [ "Choice A", new inquirer.Separator(), "choice B" ]
+
+// Which'll be displayed this way
+[?] What do you want to do?
+ > Order a pizza
+ Make a reservation
+ --------
+ Ask opening hours
+ Talk to the receptionist
+```
+
+The constructor takes a facultative `String` value that'll be use as the separator. If omitted, the separator will be `--------`.
+
+Separator instances have a property `type` equal to `separator`. This should allow tools façading Inquirer interface from detecting separator types in lists.
+
+
+
+### Prompt types
+
+---
+
+> **Note:**: _allowed options written inside square brackets (`[]`) are optional. Others are required._
+
+#### List - `{type: 'list'}`
+
+Take `type`, `name`, `message`, `choices`[, `default`, `filter`] properties. (Note that
+default must be the choice `index` in the array or a choice `value`)
+
+
+
+---
+
+#### Raw List - `{type: 'rawlist'}`
+
+Take `type`, `name`, `message`, `choices`[, `default`, `filter`] properties. (Note that
+default must be the choice `index` in the array)
+
+
+
+---
+
+#### Expand - `{type: 'expand'}`
+
+Take `type`, `name`, `message`, `choices`[, `default`] properties. (Note that
+default must be the choice `index` in the array. If `default` key not provided, then `help` will be used as default choice)
+
+Note that the `choices` object will take an extra parameter called `key` for the `expand` prompt. This parameter must be a single (lowercased) character. The `h` option is added by the prompt and shouldn't be defined by the user.
+
+See `examples/expand.js` for a running example.
+
+
+
+
+---
+
+#### Checkbox - `{type: 'checkbox'}`
+
+Take `type`, `name`, `message`, `choices`[, `filter`, `validate`, `default`] properties. `default` is expected to be an Array of the checked choices value.
+
+Choices marked as `{checked: true}` will be checked by default.
+
+Choices whose property `disabled` is truthy will be unselectable. If `disabled` is a string, then the string will be outputted next to the disabled choice, otherwise it'll default to `"Disabled"`. The `disabled` property can also be a synchronous function receiving the current answers as argument and returning a boolean or a string.
+
+
+
+---
+
+#### Confirm - `{type: 'confirm'}`
+
+Take `type`, `name`, `message`, [`default`] properties. `default` is expected to be a boolean if used.
+
+
+
+---
+
+#### Input - `{type: 'input'}`
+
+Take `type`, `name`, `message`[, `default`, `filter`, `validate`, `transformer`] properties.
+
+
+
+---
+
+#### Input - `{type: 'number'}`
+
+Take `type`, `name`, `message`[, `default`, `filter`, `validate`, `transformer`] properties.
+
+---
+
+#### Password - `{type: 'password'}`
+
+Take `type`, `name`, `message`, `mask`,[, `default`, `filter`, `validate`] properties.
+
+
+
+---
+
+Note that `mask` is required to hide the actual user input.
+
+#### Editor - `{type: 'editor'}`
+
+Take `type`, `name`, `message`[, `default`, `filter`, `validate`] properties
+
+Launches an instance of the users preferred editor on a temporary file. Once the user exits their editor, the contents of the temporary file are read in as the result. The editor to use is determined by reading the $VISUAL or $EDITOR environment variables. If neither of those are present, notepad (on Windows) or vim (Linux or Mac) is used.
+
+
+
+## User Interfaces and layouts
+
+Along with the prompts, Inquirer offers some basic text UI.
+
+#### Bottom Bar - `inquirer.ui.BottomBar`
+
+This UI present a fixed text at the bottom of a free text zone. This is useful to keep a message to the bottom of the screen while outputting command outputs on the higher section.
+
+```javascript
+var ui = new inquirer.ui.BottomBar();
+
+// pipe a Stream to the log zone
+outputStream.pipe(ui.log);
+
+// Or simply write output
+ui.log.write('something just happened.');
+ui.log.write('Almost over, standby!');
+
+// During processing, update the bottom bar content to display a loader
+// or output a progress bar, etc
+ui.updateBottomBar('new bottom bar content');
+```
+
+
+
+## Reactive interface
+
+Internally, Inquirer uses the [JS reactive extension](https://github.com/ReactiveX/rxjs) to handle events and async flows.
+
+This mean you can take advantage of this feature to provide more advanced flows. For example, you can dynamically add questions to be asked:
+
+```js
+var prompts = new Rx.Subject();
+inquirer.prompt(prompts);
+
+// At some point in the future, push new questions
+prompts.next({
+ /* question... */
+});
+prompts.next({
+ /* question... */
+});
+
+// When you're done
+prompts.complete();
+```
+
+And using the return value `process` property, you can access more fine grained callbacks:
+
+```js
+inquirer.prompt(prompts).ui.process.subscribe(onEachAnswer, onError, onComplete);
+```
+
+## Support (OS Terminals)
