- Added the option to set the sass and css folders in the grunt config
file so you don't have to create a separate compass configuration file
- updated the read me to reflect these changes

 1. Place the `grunt-compass` folder in the root of your project.
 2. Call `grunt.loadTasks('grunt-compass/tasks');` in your gruntfile.
 3. Configure `grunt watch` to watch your scss files and call the task.
-e.g.:
-
-````javascript
-watch: {
-    files: ['assets/scss/partials/*.scss'],
-    tasks: ['compass']

+	e.g.:

+	watch: {
+	    files: ['assets/scss/partials/*.scss'],
+	    tasks: ['compass']
+	}

+
+4. Setup the config for compass in your grunt config, or setup a compass config file:
+	* Option 1: Set the configuration for compass in your grunt.js file:
+
+		```javascript
+		compass: {
+		  src: 'assets/scss/partials',
+		  dest: 'assets/css/partials'
+		}
+		```
+
+		"src" is the folder with sass/scss files.
+		"dest" is the file where the css files will be place.
+	* Option 2: Setup a compass project
+		```
+		compass install compass
+		```
+5. Run "grunt watch" and change some SASS files :)
+
+**Notice:** At this moment this task doesn't work with "grunt" or "grunt compass" it only creates the folders, not the files!
