Notes: Be aware that Sigil-0.9.17 no longer enforces the need for epub3 to have and support an NCX for the purposes of backward compatibility with epub2 reading systems. There are, however, built-in tools to allow users to add backward compatibility features such as the NCX to their epub3. Please check the Sigil Wiki for important Sigil support links, additional resource downloads, and platform-specific trouble-shooting tips/requirements.
