2. Modify assetManager in your configuration file {app}/protected/config/main.php

    'assetManager' => [
        'bundles' => require(__DIR__ . '/assets.php'),
        'converter'=> [
            'class'=>'nizsheanez\assetConverter\Converter',
        ]

3. Create .gitignore in
4. Enjoy!

• Files with extension .sass are converted to a .css file
• Files with extension .less are converted to a .css file

###Example of assets config file /protected/config/assets.php

return [
	'app' => [
		'basePath' => '@webroot',
		'baseUrl' => '@web',
        'css' => [
			'css/bootstrap.min.css',
			'css/bootstrap-responsive.min.css',
			'css/site.css',
            'css/less_style.less',
            'css/sass_style.sass',
		],
		'js' => [

		],
		'depends' => [
			'yii',
		],
	],
];

###Where is compiled files?

By default it present at @webroot/compiled But you can change it by destinationDir property from config

Full configuration

'components' => [
	'assetManager' => [
        'converter'=> [
            'class'=> 'nizsheanez\assetConverter\Converter',
            'force'=> false, // true : If you want convert your sass each time without time dependency
            'destinationDir' => 'compiled', //at which folder of @webroot put compiled files
            'parsers' => [
                'sass' => [ // file extension to parse
                    'class' => 'nizsheanez\assetConverter\Sass',
                    'output' => 'css', // parsed output file type
                    'options' => [
                        'cachePath' => '@app/runtime/cache/sass-parser' // optional options
                    ],
                ],
                'scss' => [ // file extension to parse
                    'class' => 'nizsheanez\assetConverter\Sass',
                    'output' => 'css', // parsed output file type
                    'options' => [] // optional options
                ],
                'less' => [ // file extension to parse
                    'class' => 'nizsheanez\assetConverter\Less',
                    'output' => 'css', // parsed output file type
                    'options' => [
		    	'importDirs' => [], // import paths, you may use path alias here ex. '@app/assets/common/less'
                        'auto' => true, // optional options
                    ]
                ]
            ]
        ]
    ],
],

Also, for SCSS files you can use alternate configuration:

'components' => [
    'assetManager' => [
            'converter'=> [
                // ...
                'parsers' => [
                    // ...
                    'scss' => [ // file extension to parse
                        'class' => 'nizsheanez\assetConverter\Scss',
                        'output' => 'css', // parsed output file type
                        'options' => [ // optional options
                            'enableCompass' => true, // default is true
                            'importPaths' => [], // import paths, you may use path alias here, 
                                // e.g., `['@path/to/dir', '@path/to/dir1', ...]`
                            'lineComments' => false, // if true — compiler will place line numbers in your compiled output
                            'outputStyle' => 'nested', // May be `compressed`, `crunched`, `expanded` or `nested`,
                                // see more at http://sass-lang.com/documentation/file.SASS_REFERENCE.html#output_style
                        ],
                    ],
                ],
            ],
        ],
    // ...
