-PostCSS syntax highlighting for Sublime Text. This package is fork of [Syntax Highlighting for Sass] by @P233 with few changes making this more useful rather Sass package:
+PostCSS syntax highlighting for Sublime Text. 
 
-* Using SCSS syntax highlighting. This covers most of PostCSS possible syntax. Removed `Sass` syntax highlighting and all Sass completions;
-* Support for CSS custom properties `var(--variable-name)` and `--variable-name`;
-* Automatic enable syntax highlighting by `*.pcss` and `*.postcss` file extensions;
-* Standard CSS comments (`/* comment */`) instead of Sass single line comments (`// comment`).
-* Supports [SugarSS syntax]
+* Support CSS-like syntax and [SugarSS] syntax.
+* Support for CSS custom properties `var(--variable-name)` and `--variable-name`, and dollar variables `$variable`;
+* Automatic enable syntax highlighting for `*.pcss` and `*.postcss` files (CSS-like syntax), and for `*.sss` (SugarSS);
 
 There is a lot of possible improvements can be made to this syntax, but frankly, I don't understand in syntax files much and hope for the help of the community.
