 * Allow Libation to fix up audiobook metadata. After decrypting a title, Libation attempts to fix details like chapters and cover art. Some power users and/or control freaks prefer to manage this themselves. By unchecking this setting, Libation will only decrypt the book and will leave metadata as-is, warts and all.
 
-### Custom File Naming
-
-In Settings, on the Download/Decrypt tab, you can specify the format in which you want your files to be named. As you edit these templates, a live example will be shown. Parameters are listed for folders, files, and files split by chapter including an explanation of what each naming option means. For instance: you can use template `<title short> - <ch# 0> of <ch count> - <ch title>` to create the file `A Study in Scarlet - 04 of 10 - A Flight for Life.m4b`.
-
-These templates apply to GUI and CLI.

 ### Command Line Interface

+### If you found this useful, tell a friend. If you found this REALLY useful, you can click here to [PayPal.me](https://paypal.me/mcrackan?locale.x=en_us)
+...or just tell more friends. As long as I'm maintaining this software, it will remain **free** and **open source**.
+
+
+### Setup
+In order to use the docker image, you'll need to provide it with a copy of the `AccountsSettings.json`, `Settings.json`, and `LibationContext.db` files. These files can usually be found in the Libation folder in your user's home directory. If you haven't run Libation yet, you'll need to launch it to generate these files and setup your accounts. Once you have them, copy these files to a new location, such as `/opt/libation/config`. Before using them we'll need to make a couple edits so that the filepaths referenced are correct when running from the docker image.
+
+In Settings.json, make the following changes:
+* Change `Books` to `/data`
+* Change `InProgress` to `/tmp`
+
+### Running
+Once the configuration files are copied and edited, the docker image can be run with the following command.
+```
+sudo docker run -d \
+  -v /opt/libation/config:/config \
+  -v /opt/libation/books:/data \
+  --name libation \
+  --restart=always \
+  rmcrackan/libation
+```
+
+By default the container will scan for new books every 30 minutes and download any new ones. This is configurable by passing in a value for the `SLEEP_TIME` environment variable. Additionally, if you pass in `-1` it will scan and download books once and then exit.
+
+```
+sudo docker run -d \
+  -v /opt/libation/config:/config \
+  -v /opt/libation/books:/data \

+##### Which version? Chardonnay vs Classic
+
+Nearly 100% of the difference is look and feel -- it's a matter of preference.
+
+Chardonnay has an updated look and will work and look the same on Windows, Mac, and Linux.  
+Classic is Windows only. It has an older look because it's built with older, duller, and more mature technology. This tech has built into it better support for things like accessibility for screen readers.
+
 ### Installation
 
 * Windows
 
 Extract the zip file to a folder and then run `Libation.exe` from inside of that folder. Do not put it in Program Files. The inability to edit files from there causes problems with configuration and updating.

 This walkthrough should get you up and running with Libation on your Mac.
 
 ## Install Libation
 
-- Download latest MacOS zip to downloads folder
-- Extract and rename folder to Libation
-- in terminal type cd and then drag your folder of libation to terminal so it looks like `cd/users/YourName/Downloads/Libation`
-- Type following commands
+- Download the `Libation.app-macOS-x64-x.x.x.tgz` file from the latest release and extract it. 
+- Move the extracted Libation app bundle to your applications folder.
+- Open a terminal (Go > Utilities > Terminal)
+- Copy/paste/run the following command (you'll be prompted to enter your password)
+  
+  ```Console
+  sudo spctl --master-disable && sudo spctl --add --label "Libation" /Applications/Libation.app && open /Applications/Libation.app && sudo spctl --master-enable
+  ```  
+- Close the terminal and use Libation!
 
-```console
-chmod +x ./Libation
-sudo spctl --add --label "Libation" ./Libation
-./Libation
+## Running Hangover
+
+Libation comes with a recovery app called Hangover. You can start it by running this command:
+```Console
+open /Applications/Libation.app --args hangover
 ```
 
-## Trouble with Gatekeeper?
+## Runnign LibationCli
 
-If Gatekeeper is giving you trouble with Libation:
+Libation comes with a command-line interface. Unfortunately, due to the way apps are sandboxed on mac, its use is somewhat limited. To open a new sandboxed terminal in LibationCli's directory, run the following command:
+```Console
+open /Applications/Libation.app --args cli
+```
+To use LibationCli from an unsandboxed terminal, you must disable gatekeeper again and run the program directly at `/Applications/Libation.app/Contents/MacOS/LibationCli`
 
-Disable the block
+Then use `./LibationCli` to execute a command.
 
-`sudo spctl --master-disable`
+## Get Libation running on Mac
 
-Launch Libation and login, etc. and allow the rules to update then re-enable the block.
-
-`sudo spctl --master-enable`
-
-Once Gatekeeper reenabled, you can open Libation again without it being blocked.

+# Naming Templates
+File and Folder names can be customized using Libation's built-in tag template naming engine. To edit how folder and file names are created, go to Settings \> Download/Decrypt and edit the naming templates. If you're splitting your audiobook into multiple files by chapter, you can also use a custom template to set each chapter's title metadata tag by editing the template in Settings \> Audio File Options.
+
+These templates apply to both GUI and CLI.

+# Template Tags
+
+These are the naming template tags currently supported by Libation.
+
+## Property Tags
+These tags will be replaced in the template with the audiobook's values.
+
+|Tag|Description|Type|
+|-|-|-|
+|\<id\> **†**|Audible book ID (ASIN)|Text|
+|\<title\>|Full title|Text|
+|\<title short\>|Title. Stop at first colon|Text|
+|\<author\>|Author(s)|Name List|
+|\<first author\>|First author|Text|
+|\<narrator\>|Narrator(s)|Name List|
+|\<first narrator\>|First narrator|Text|
+|\<series\>|Name of series|Text|
+|\<series#\>|Number order in series|Text|
+|\<bitrate\>|File's original bitrate (Kbps)|Integer|
+|\<samplerate\>|File's original audio sample rate|Integer|
+|\<channels\>|Number of audio channels|Integer|
+|\<account\>|Audible account of this book|Text|
+|\<locale\>|Region/country|Text|
+|\<year\>|Year published|Integer|
+|\<language\>|Book's language|Text|
+|\<language short\> **†**|Book's language abbreviated. Eg: ENG|Text|
+|\<file date\>|File creation date/time.|DateTime|
+|\<pub date\>|Audiobook publication date|DateTime|
+|\<date added\>|Date the book added to your Audible account|DateTime|
+|\<ch count\> **‡**|Number of chapters|Integer|
+|\<ch title\> **‡**|Chapter title|Text|
+|\<ch#\> **‡**|Chapter number|Integer|
+|\<ch# 0\> **‡**|Chapter number with leading zeros|Integer|
+
+**†** Does not support custom formatting
+
+**‡** Only valid for Chapter Filename and Chapter Tile Metadata
+
+To change how these properties are displayed, [read about custom formatters](#tag-formatters)
+
+## Conditional Tags
+Anything between the opening tag (`<tagname->`) and closing tag (`<-tagname>`) will only appear in the name if the condition evaluates to true. 
+
+|Tag|Description|Type|
+|-|-|-|
+|\<if series-\>...\<-if series\>|Only include if part of a book series or podcast|Conditional|
+|\<if podcast-\>...\<-if podcast\>|Only include if part of a podcast|Conditional|
+|\<if bookseries-\>...\<-if bookseries\>|Only include if part of a book series|Conditional|
+
+For example, <if podcast-\>\<series\>\<-if podcast\> will evaluate to the podcast's series name if the file is a podcast. For audiobooks that are not podcasts, that tag will be blank.
+
+You can invert the condition (instead of displaying the text when the condition is true, display the text when it is false) by playing a '!' symbol before the opening tag name.
+
+As an example, this folder template will place all Liberated podcasts into a "Podcasts" folder and all liberated books (not podcasts) into a "Books" folder.
+
+\<if podcast-\>Podcasts<-if podcast\>\<!if podcast-\>Books\<-if podcast\>\\\<title\>
+
+
+# Tag Formatters
+**Text**, **Name List**, **Integer**, and **DateTime** tags can be optionally formatted using format text in square brackets after the tag name. Below is a list of supported formatters for each tag type.
+
+## Text Formatters
+|Formatter|Description|Example Usage|Example Result|
+|-|-|-|-|
+|L|Converts text to lowercase|\<title[L]\>|a study in scarlet꞉ a sherlock holmes novel|
+|U|Converts text to uppercase|\<title short[U]\>|A STUDY IN SCARLET|
