 * **&lt;AAX INPUT_FILES&gt;**... are considered input file(s), useful for batching!
 
-## Options ##
+## Options
 * **-f** or **--flac**   Flac Encoding and Produces a single file.
 * **-o** or **--opus**   Ogg/Opus Encoding defaults to multiple file output by chapter. The extention is .ogg
 * **-a** or **--aac**    AAC Encoding and produce a m4a single files output.
-* **-s** or **--single** Output a single file. If you only want a single ogg file for instance.
 * **-A** or **--authcode &lt;AUTHCODE&gt;** for this execution of the command use the provided &lt;AUTHCODE&gt; to decode the AAX file.
 * **-t** or **--target_dir &lt;PATH&gt;** change the default output location to the named &lt;PATH&gt;. Note the default location is ./Audiobook of the directory to which each AAX file resides.
 * **-e:mp3**         Identical to defaults.
 * **-e:m4a**         Create a m4a audio file. This is identical to --aac
 * **-e:m4b**         Create a m4b aduio file. This is the book version of the m4a format. 
+* **-s** or **--single**    Output a single file for the entire book. If you only want a single ogg file for instance.
+* **-c** or **--chaptered** Output a single file per chapter. The --chaptered will only work if it follows the -aac -e:m4a -em4b options. 
+
+
+### [AUTHCODE] 
+**Your** Audible auth code (it won't correctly decode otherwise) (required).
+
+#### Determining your own AUTHCODE
+You will need your authentication code that comes from Audible's servers. This 
+will be used by ffmpeg to perform the initial audio convert. You can obtain 
+this string from a tool like 
+[audible-activator](https://github.com/inAudible-NG/audible-activator).
+
+#### Specifying the AUTHCODE.
+    In order of __precidence__.
+    1. __--authcode [AUTHCODE]__ The command line option. With the highest precidence.
+    2. __.authcode__ If this file is placed in the current working directory and contains only the authcode it is used if the above is not.
+    3. __~/.authcode__ a global config file for all the tools. And is used as the default if none of the above are specified.
+__Note:__ At least one of the above must be exist. The code must also match the encoding for the user that owns the AAX file(s). If the authcode does not match the AAX file no transcoding will occure.
+
 
 ### MP3 Encoding
 * This is the **default** encoding
-* Produces 1 or more mp3 files for the AAX title.  If you desire a single file use the **--single** option
+* Produces 1 or more mp3 files for the AAX title.
-* If you want a mp3 file per chapter do not use the -single option. Note a m3u playlist file will also be created in this instance.
+* The default mode is **chaptered**
+* If you want a mp3 file per chapter do not use the -single option. 
+* A m3u playlist file will also be created in this instance in the case of **default** chaptered ouput.
 
 ### Ogg/Opus Encoding
 * Can be done by using the **-o** or **--opus** command line switches
-* Is designed to efficiently code speech and general audio in a **--single** format
+* The default mode is **chaptered**
 * Opus coded files are stored in the ogg container format for better compatibility.
 
 ### AAC Encoding
 * Can be done by using the **-a** or **--aac** command line switches
+* The default mode is **single**
 * Designed to be the successor of the MP3 format
 * Generally achieves better sound quality than MP3 at the same bit rate.
 * This will only produce 1 audio file as output.
 
 ### FLAC Encoding
 * Can be done by using the **-f** or **--flac** command line switches
+* The default mode is **single**
 * FLAC is an open format with royalty-free licensing
+* Note: There is an bug with the ffmpeg software that prevents the splitting of flac files. Chaptered output of flac files will fail.
