In addition, where it's made\nsense for a transform, we've added [Browserslist](https://github.com/ai/browserslist)\nto provide different output depending on the browsers that you support.\n\nFor further details check out the [website](https://cssnano.github.io/cssnano):\n\n- [Installation guide for your build process](https://cssnano.github.io/cssnano/docs/getting-started).\n- [Full list of optimisations](https://cssnano.github.io/cssnano/docs/what-are-optimisations/).\n\nYou can now [try cssnano online](https://cssnano.github.io/cssnano/playground/)!\n\n## Contributing\n\nSee [CONTRIBUTING.md](CONTRIBUTING.md).\n\n## Contributors\n\nThis project exists thanks to all the people who contribute.
