Your first book and interface
Choose your language during first launch and continue Free, or enter your existing Pro token. Create a book with a recognizable title. In Books, open it and use Structure to add a chapter. Click the chapter to write; the editor saves changes automatically. Allow saving to finish before closing or switching your workspace.
The left navigation opens app sections. The writing sidebar opens the book’s pages; the right rail contains contextual tools such as Notes, Review, Preview and Comments. Close a rail or use the existing focus controls when you need writing space. Hidden sections may be disabled in Plugins; they are not necessarily missing data.
