# Folder structure {#structure} A Bookup project folder structure looks like this: * `archive`: stores old book versions. * `content`: the actual content: * `drafts`: you can leave here texts still being composed. * `sections`: here goes the material to be compiled in book format. * `notes`: keep texts here to be compiled as a notebook companion. * `slides`: slides in Markdown format. * `site`: an optional website used as base; if that exists, the book will be place inside the `build/book` folder. * `build`: the compiled book (HTML, PDF and other formats): * `notes`: the compiled notebook. * `book`: the compiled book, if there's a `site` folder available, otherwise the book content will be placed in the toplevel `build` folder. * `biblio`: bibliography (BibTeX). * `images`: image folder. * `vendor/bookup`: where the Bookup codebase actually resides: * `content`: Bookup documentation. * `vendor/{Fuse.js,}`: dependencies.
