If you have been using Evernote as your note management solution and want to move your notes into Notebooks, you can do so with a few simple steps:
  1. Export your Evernote notes in .enex format.
  2. Move the resulting file into Notebooks. You can do so by dragging it into a book in Notebooks’ outline or document list.
  3. Select the file in Notebooks. 
  4. Notebooks displays some status info and an import button In the right window. Click that button to extract your notes contained in the enex file and add them to Notebooks.
  5. Wait until the process has finished and you are done. You can now continue to work on your documents directly in Notebooks.
