In the web editor, you can organize the contents of your book via a drag and drop interface. This is obviously not available if you're working offline. Instead, you'll notice a
Contents.txt file (hidden in the Penflip web editor), which achieves the same goal: displaying and organizing the contents of your book.
The Contents.txt file should contain a list of files to be included in your compiled book. The structure is simple: list one filepath per line. You can add, remove, or rearrange filepaths as necessary. Only the files listed in Contents.txt will be included in your project when it is exported.
An example Contents file:
About.md introduction.md part-1/chapter1.md part-1/chapter2.md part-2/chapter3.md end.md
Filepaths are case-insensitive.
