 ##Usage
 ```javascript
 var scraper = require('website-scraper'); 
-scraper.scrape({
+var options = {
   url: 'http://nodejs.org/',
-  path: '/path/to/save/',
-}, function (error, result){
+  directory: '/path/to/save/',
+};
+
+// with callback
+scraper.scrape(options, function (error, result) {
+	/* some code here */
+});
+
+// or with promise
+scraper.scrape(options).then(function (result) {
 	/* some code here */
 });
 ```
 
 ##API
 ### scrape(options, callback)
-Makes request to `url` and saves all files found with `srcToLoad` to `path`. 
+Makes request to `url` and saves all files found with `srcToLoad` to `directory`. 
 
 **options** - object containing next options:
 
  - `url:` url to load *(required)*
- - `path:` path to save loaded files *(required)*
+ - `directory:` path to save loaded files *(required)*

  - `log:` boolean indicates whether to write the log to console *(optional, default: false)*
  - `indexFile:` filename for index page *(optional, default: 'index.html')*
  - `srcToLoad:` array of objects to load, specifies selectors and attribute values to select files for loading *(optional, see default value in `lib/defaults.js`)*
- - `directories:` array of objects, specifies relative directories for extensions. If `null` all files will be saved to `path` *(optional, see example below)*
+ - `subdirectories:` array of objects, specifies subdirectories for extensions. If `null` all files will be saved to `directory` *(optional, see example below)*
 
 
 **callback** - callback function *(optional)*, includes following parameters:
 
   - `error:` if error - `Error object`, if success - `null`

+    - `url:` url of loaded page
+    - `filename:` absolute filename where page was saved
 
 
 ##Examples
-Let's scrape [http://nodejs.org/](http://nodejs.org/) with images, css, js files and save them to `/path/to/save/`. Index page will be named 'myIndex.html', files will be separated into directories:
+Let's scrape some pages from [http://nodejs.org/](http://nodejs.org/) with images, css, js files and save them to `/path/to/save/`. 
+Imagine we want to load:
+  - [Home page](http://nodejs.org/) to `index.html`
+  - [About page](http://nodejs.org/about/) to `about.html`
+  - [Blog](http://blog.nodejs.org/) to `blog.html`
+  
+and separate files into directories:
 
-  - `img` for .jpg, .png (full path `/path/to/save/img`) 
+  - `img` for .jpg, .png, .svg (full path `/path/to/save/img`) 
   - `js` for .js (full path `/path/to/save/js`)
   - `css` for .css (full path `/path/to/save/css`)
-  - `font` for .ttf, .woff, .eot, .svg (full path `/path/to/save/font`)
