 ## Additional info
 
-All styles (as well as scripts and templates) added to `src/app/` and `src/common/` should be included to the project automatically - with a small difference to `src/sass/` folder. Partials SASS files (such as variables, mixins, etc.) put into `src/sass/includes/` must be manually imported in `src/sass/_includes.scss` file (you may want to set custom order for loading your styles). Partials located in `src/sass/_includes/` should be named with a leading underscore `_`, so the compiler knows not to generate them into a CSS file (see [SASS official site](http://sass-lang.com/guide#topic-4) for details).

+## Known issues
+
+Support for source maps in the latest version of node-sass (v0.9.1) is broken, so older version of gulp-sass (depending on older node-sass) will be used as a temporary solution (see the discussions at [gulp-sass](https://github.com/dlmanning/gulp-sass/issues/57) and [node-sass](https://github.com/sass/node-sass/issues/337)).

 ## TODO
