 ## CSS
 
-prawn-svg uses the css_parser gem to parse CSS <tt>&lt;style&gt;</tt> blocks.  It only handles simple tag, class or id selectors; attribute and other advanced selectors are not supported by the gem.
+prawn-svg supports CSS, both in `<style>` blocks and `style` attributes.
 
+In CSS selectors you can use element names, IDs, classes, attributes (existence, `=`, `^=`, `$=`, `*=`, `~=`, `|=`)
+and all combinators (` `, `>`, `+`, `~`).
+The pseudo-classes `:first-child`, `:last-child` and `:nth-child(n)` (where n is a number) also work.
+
+Pseudo-elements and the other pseudo-classes are not supported.  Specificity ordering is
+implemented, but `!important` is not.
+
 ## Not supported
 
 prawn-svg does not support radial gradients, patterns or filters.
+
+It does not support text in the clip area, but you can clip shapes and text by any shape.
