Ionic has introduced a new feature in version 1.3.19 of its CLI, designed to improve access to documentation, enhancing the ease of development. The "ionic docs" command allows users to quickly access specific sections of the Ionic framework documentation through their browser. Users can explore all help documents with "ionic docs ls" or receive suggestions for document names using "ionic docs repeat" if they are unsure of the exact title. The update encourages developers to install the latest version of the Ionic CLI via npm to benefit from these new documentation access features.
