+node.js Backup & Restore
+========================
+
+Easy Backup & Restore web site project. All files and directories are written to one file (and files are compressed via GZIP).
+
+* Backup file is text file
+* Supports backup and restore: files and directories
+* Simple filtering files and directories
+* Simple structure
+* Easy manipulation
+* Easy use in your project
+* Executables *backup* and *restore* from terminal
+* __No dependencies__
+
+## Installation
+
+```
+$ sudo npm install -g backup
+
+// or
+
+$ npm install backup
+```
+
+## node.js
+
+```js
+var backup = require('backup');
+
+/*
+	Backup directory to file
+	
+	@directory {String}
+	@filename {String},
+	@complete {Function} :: optional, param: @err {Error}, @filename {String}
+	@filter {Function} :: optional, param: @path {String} return TRUE | FALSE, if FALSE file or directory will be skipped
+*/
+backup.backup('/path/to/directory/', '/users/petersirka/desktop/website.backup');

+```
+
+## BINARY
+
+```
+// backup current directory
+// $ backup @filename
+$ backup /users/petersirka/desktop/website.backup
