-You'll only need to pass a type into `ext` and it'll figure the rest out for
-you.

 ```js
-var decompress = require('decompress');
-var fs = require('fs');
+var Decompress = require('decompress');
+var decompress = new Decompress()
+    .src('foo.zip')
+    .dest('destFolder')

 ```
 
-## API
-
-### decompress(opts)
-
-Extract an archive using the `ext` option to determine which extractor to use.
-If no `path` is specified it'll extract it to your current location.
-
-### decompress.canExtract(src, mime)
-
-Determine if a file can be extracted or not by checking the file extension
-and/or the MIME type.
-
-```js
-decompress.canExtract('foo.zip');
-// => true
-
-decompress.canExtract('application/zip');
-// => true
-```
-
-## Options
-
-### `ext`
-
-Type: `String`  
-Default: `''`
-
-String that can be a file name, URL, MIME type etc.
-
-### `path`
-
-Type: `String`  
-Default: `process.cwd()`
-
-Path to extract the archive to. If no `path` is defined it'll extract it to your
-current location.
-
-### `strip`
-
-Type: `Number`  
-Default: `0`
-
-Equivalent to `--strip-components` for tar.
-
-## CLI

-```bash
-$ npm install --global decompress

-```bash
-$ decompress --help
-
-Usage
-  $ decompress <file>
-  $ cat <file> | decompress
-
-Example
-  $ decompress --out dist --strip 1 archive.zip
-  $ cat files.txt | decompress --out dist
-
-Options
-  -o, --out <path>        Path to extract the archive to
-  -s, --strip <number>    Strip path segments from root when extracting
