   To use this option add the optional environmental variable as shown in the docker-mods section to pull an addition docker layer to enable ebook conversion and then in the Calibre-Web admin page (Basic Configuration:External Binaries) set the **Path to Calibre E-Book Converter** to `/usr/bin/ebook-convert` on versions 0.6.21 and lower. For 0.6.22 and higher, set the directory, `/usr/bin/` only.
