 This page is for people that want to try the dual-mode combining Boosted and OUDS Web. It also works as a tutorial to implement OUDS Web gradually inside your website. Be careful, we will support this in a “best-effort” way ; this feature is supposed to be mainly used by pre-selected projects. If you need any assistance, please [contact us]([[docsref:/about/team]]).
 This page is not to be used alone, but is complementary to [OUDS Web documentation](https://web.unified-design-system.orange.com/) and [Boosted documentation](https://boosted.orange.com/).
