-Thanks to thibaudcolas, this script has been tested on OSX 10.11.6 El Capitan. YMMV, but it should work for 
-conversions in OSX. It is recommended that you install GNU grep using 'brew install grep' for chapter padding to work.

-## AUR
-Thanks to kbabioch, this script has also been packaged in the [AUR](https://aur.archlinux.org/packages/aaxtomp3-git/). Note that you will still need to extract your activation bytes before use.

+## AAXC files
+The AAXC format is a new Audible encryption format, meant to replace the old AAX.
+The encryption has been updated, and now to decrypt the file the authcode
+is not sufficient, we need two "keys" which are unique for each audiobook.
+Since getting those keys is not simple, for now the method used to get them
+is handled by the package audible-cli, that stores
+them in a file when downloading the aaxc file. This means that in order to
+decrypt the aaxc files, they must be downloaded with audible-cli.
+Note that you need at least [ffmpeg 4.4](#ffmpegffprobe).
 
+## Audible-cli integration
+Some information are not present in the AAX file. For example the chapters's
+title, additional chapters division (Opening and End credits, Copyright and
+more).  Those information are avaiable via a non-public audible API. This
+[repo](https://github.com/mkb79/Audible) provides a python API wrapper, and the
+[audible-cli](https://github.com/mkb79/audible-cli) packege makes easy to get
+more info. In particular the flags **--cover --cover-size 1215 --chapter**
+downloads a better-quality cover (.jpg) and detailed chapter infos (.json).
+More info are avaiable on the package page.
+
+Some books might not be avaiable in the old `aax` format, but only in the newer
+`aaxc` format. In that case, you can use [audible-cli](https://github.com/mkb79/audible-cli)
+to download them. For example, to download all the books in your library in the newer `aaxc` format, as well as
+chapters's title and an HQ cover: `audible download --all --aaxc --cover --cover-size 1215 --chapter`.
+
+To make AAXtoMP3 use the additional data, specify the **--use-audible-cli-data**
+flag: it expects the cover and the chapter files (and the voucher, if converting
+an aaxc file) to be in the same location of the AAX file.  The naming of these
+files must be the one set by audible-cli. When converting aaxc files, the variable
+is automatically set, so be sure to follow the instructions in this paragraph.
+
+For more information on how to use the `audible-cli` package, check out the git page [audible-cli](https://github.com/mkb79/audible-cli).
+
+Please note that right now audible-cli is in dev stage, so keep in mind that the
+naming scheme of the additional files, the flags syntax and other things can
+change without warning.
