+Comparison with other libraries
+-------------------------------
+
+Besides performance, `css-inline` differs from other Python libraries for CSS inlining.
+
+- Generally supports more CSS features than other libraries (for example, `toronado` and `pynliner` do not support pseudo-elements);
+- It has fewer configuration options and not as flexible as `premailer`;
+- Works on fewer platforms than LXML-based libraries (`premailer`, `inlinestyler`, `toronado`, and optionally `pynliner`);
+- Does not have debug logs yet;
+- Supports only HTML 5.
