+
+### Files and folders
+
+To make upgrades and reinstalls easier, Libation separates all of its responsibilities to a few different folders. If you don't want to mess with this stuff: ignore it. Read on if you like a little more control over your files.
+
+* In Libation's initial folder are the files that make up the program. Since nothing else is here, just copy new files here to upgrade the program. Delete this folder to delete Libation.
+
+* In a separate folder, Libation keeps track of all of the files it creates like settings and downloaded images. After an upgrade, Libation might think that's its being run for the first time. Just click ADVANCED SETUP and point to this folder. Libation will reload your library and settings.
+
+* The last important folder is the "books location." This is where Libation looks for your downloaded and decrypted books. This is how it knows which books still need to be downloaded. The Audible id must be somewhere in the book's file or folder name for Libation to detect your downloaded book.
+
+### Settings
+
+* 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.
+
+In addition to the options that are enabled if you allow Libation to "fix up" the audiobook, it does the following:
+
+* Adds the `TCOM` (`@wrt` in M4B files) metadata tag for the narrators.
+* Sets the `©gen` metadata tag for the genres.
+* Unescapes the copyright symbol (replace `©` with `©`)
+* Replaces the recording copyright `(P)` string with `℗`
+* Replaces the chapter markers embedded in the aax file with the chapter markers retrieved from Audible's API.
+* Sets the embedded cover art image with the 500x500 px cover art retrieved from Audible
+
+### Command Line Interface
+
+Libationcli.exe allows limited access to Libation's functionalities as a CLI.
+
+Warnings about relying solely on on the CLI:
+* CLI will not perform any upgrades.
+* It will show that there is an upgrade, but that will likely scroll by too fast to notice.
+* It will not perform all post-upgrade migrations. Some migrations are only be possible by launching GUI.

+
+
+### Disclaimer
+The docker image is provided as-is. We hope it can be useful to you but it is not officially supported.
+
+### 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 \
+  -e SLEEP_TIME='10m' \
+  --name libation \
+  --restart=always \
+  rmcrackan/libation

+
+##### 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.
+
+* [Linux](InstallOnLinux.md)
+* [MacOS](InstallOnMac.md)
+
+### Create Accounts
+
+Create your account(s):
+
+![Create your accounts, menu](images/v40_accounts.png)
+
+New locale options include many more regions including old audible accounts which pre-date the amazon acquisition
+
+![Choose your account locales](images/v40_locales.png)
+
+### Import your library
+
+Be default, Libation will periodically scan the accounts you added above with a checkbox next to them. Nothing for you to do. You can also scan manually.
+
+Select Import > Scan Library:
+
+![Import step 1](images/Import1.png)
+
+Or if you have multiple accounts, you'll get to choose whether to scan all accounts or just the ones you select:
+
+![Import which accounts](images/v40_import.png)
+
+If this is a new installation, or you're scanning an account you haven't scanned before, you'll be prompted to enter your password for the Audible account.
+
+![Login password](images/alt-login1.png)
+
+Enter the password and click Submit. Audible will prompt you with a CAPTCHA image. 
+
+![Login captcha](images/alt-login2.png)
+
+Enter the CAPTCHA answer characters and click Submit. If all has gone well, Libation will start scanning the account. 
+
+In rare instances, the Captcha image/response will fail in an endless loop. If this happens, delete the problem account, and then click Save. Re-add the account and click Save again. Now try to scan the account again. This time, instead of typing your password, click the link that says "Or click here". This will open the Audible External Login dialog shown below.
+
+![Login alternative setup](images/alt-login3.png)
+
+You can either copy the URL shown and paste it into your browser or launch the browser directly by clicking Launch in Browser. Audible will display its standard login page. Login, including answering the CAPTCHA on the next page. In some cases, you might have to approve the login from the email account associated with that login, but once the login is successful, you'll see an error message.
+
+![Login alternative login result](images/alt-login4.png)
+
+This actually means you've successfully logged in. Copy the entire URL shown in your browser and return to Libation. Paste that URL into the text box at the bottom of the Audible External Login window and click Submit.
+
+You'll see this window while it's scanning:
+
+![Import step 2](images/Import2.png)
+
+Success! We see how many new titles are imported:
+
+![Import step 3](images/Import3.png)
+
+### Download your books -- DRM-free!
+
+Automatically download some or all of your audible books. This shows you how much of your library is not yet downloaded and decrypted:
+
+The stoplights will tell you a title's status:
+
+* Green: downloaded and decrypted
+* Yellow: downloaded but still encrypted with DRM
+* Red: not downloaded
+* PDF icon without arrow: downloaded
+* PDF with arrow: not downloaded
+
+Or hover over the button to see the status.
+
+![Liberate book step 1](images/LiberateBook1.png)
+
+Select Liberate > Begin Book Backups
+
+You can also click on the stop light to download only that title and its PDF
+
+![Liberate book step 2](images/LiberateBook2.png)
+
+First the original book with DRM is downloaded
+
+![Liberate book step 3](images/LiberateBook3.png)
+
+Then it's decrypted so you can use it on any device you choose. The very first time you decrypt a book, this step will take a while. Every other book will go much faster. The first time, Libation has to figure out the special decryption key which allows your personal books to be unlocked.
+
+![Liberate book step 4](images/LiberateBook4.png)
+
+And voila! If you have multiple books not yet liberated, Libation will automatically move on to the next.
+
+![Liberate book step 5](images/LiberateBook5.png)
+
+The Audible id must be somewhere in the book's file or folder name for Libation to detect your downloaded book.
+
+### Download PDF attachments
+
+For books which include PDF downloads, Libation can download these for you as well and will attempt to store them with the book. "Book backup" will already download an available PDF. This additional option is useful when Audible adds a PDF to your book after you've already backed it up.
+
+Select Liberate > Begin PDF Backups
+
+![PDF download step 2](images/PdfDownload2.png)
+
+The downloads work just like with books, only with no additional decryption needed.
+
+![PDF download step 3](images/PdfDownload3.png)
+
+### Details of downloaded files
+
+![Post download](images/PostDownload.png)
+
+When you set up Libation, you'll specify a Books directory. Libation looks inside that directory and all subdirectories to look for files or folders with each library book's audible id. This way, organization is completely up to you. When you download + decrypt a book, you get several files
+
+* .m4b: your audiobook in m4b format. This is the most pure version of your audiobook and retains the highest quality. Now that it's decrypted, you can play it on any audio player and put it on any device. If you'd like, you can also use 3rd party tools to turn it into an mp3. The freedom to do what you want with your files was the original inspiration for Libation.
+* .cue: this is a file which logs where chapter breaks occur. Many tools are able to use this if you want to split your book into files along chapter lines.
+
+### Export your library
+
+![Export](images/Export.png)
+
+Export your library to Excel, CSV, or JSON

+# Run Libation on MacOS
+This walkthrough should get you up and running with Libation on your Mac.
+
+## Supports macOS 10.15 (Catalina) and above
+
+## Install Libation
+
+- Download the file from the latest release and extract it.
+  - Apple Silicon (M1, M2, ...): `Libation.9.4.2-macOS-chardonnay-`**arm64**`.tgz`
+  - Intel: `Libation.x.x.x-macOS-chardonnay-`**x64**`.tgz`
+- 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!
+
+## 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
+```
+
+## Runnign LibationCli
+
+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`
+
+Then use `./LibationCli` to execute a command.

+# 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.

+## Property Tags
+These tags will be replaced in the template with the audiobook's values.
+
+|Tag|Description|Type|

+|\<locale\>|Region/country|Text|
+|\<year\>|Year published|Number|
+|\<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|Number|
+|\<ch title\> **‡**|Chapter title|Text|
+|\<ch#\> **‡**|Chapter number|Number|
+|\<ch# 0\> **‡**|Chapter number with leading zeros|Number|
+
+**†** 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|
+|\<if podcastparent-\>...\<-if podcastparent\>**†**|Only include if item is a podcast series parent|Conditional|
+
+**†** Only affects the podcast series folder naming if "Save all podcast episodes to the series parent folder" option is checked.
+
+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**, **Number**, 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

+- [Filters](#filters)
+
+
+
+### Tags
+
+To add tags to a title, click the tags button
+
+![Tags step 1](images/Tags1.png)
+
+Add as many tags as you'd like. Tags are separated by a space. Each tag can contain letters, numbers, and underscores
+
+![Tags step 2](images/Tags2.png)
+
+Tags are saved non-case specific for easy search. There is one special tag "hidden" which will also grey-out the book
+
+![Tags step 3](images/Tags3.png)
+
+To edit tags, just click the button again.
+
+### Searches
+
+Libation's advanced searching is built on the powerful Lucene search engine. Simple searches are effortless and powerful searches are simple. To search, just type and click Filter or press enter
+
+* Type anything in the search box to search common fields: title, authors, narrators, and the book's audible id
+* Use Lucene's "Query Parser Syntax" for advanced searching.
+    * Easy tutorial: http://www.lucenetutorial.com/lucene-query-syntax.html
+    * Full official guide: https://lucene.apache.org/core/2_9_4/queryparsersyntax.html
+* Tons of search fields, specific to audiobooks
+* Synonyms so you don't have to memorize magic words. Eg: author and author**s** will both work
+* Click [?] button for a full list of search fields and synonyms ![Filter options](images/FilterOptionsButton.png)
+* Search by tag like \[this\]
+* When tags have an underscore you can use part of the tag. This is useful for quick categories. The below examples make this more clear.
+
+### Search examples
+
+Search for anything with the word potter
+
+![Search example: potter](images/SearchExamplePotter.png)
+
+If you only want to see Harry Potter
+
+![Search example: "harry potter"](images/SearchExampleHarryPotter.png)
+
+If you only want to see potter except for Harry Potter. You can also use "-" instead of "NOT"
+
+![Search example: "potter NOT harry"](images/SearchExamplePotterNotHarry.png)
+![Search example: "potter -harry"](images/SearchExamplePotterNotHarry2.png)
+
+To see only books written by Neil Gaiman where he also narrates his own book. (If you don't include AND, you'll see everything written by Neil Gaiman and also all books in your library which are self-narrated.)
+
+![Search example: author:gaiman AND authornarrated](images/SearchExampleGaimanAuthorNarrated.png)
+
+I tagged autobiographies as auto_bio and biographies written by someone else as bio. I can get only autobiographies with \[auto_bio\] or get both by searching \[bio\]
+
+![Search example: \[bio\]](images/SearchExampleBio.png)
+![Search example: \[auto_bio\]](images/SearchExampleAutoBio.png)
+
+### Filters
+
+If you have a search you want to save, click Add To Quick Filters to save it in your Quick Filters list. To use it again, select it from the Quick Filters list.
+
+To edit this list go to Quick Filters > Edit quick filters. Here you can re-order the list, delete filters, double-click a filter to edit it, or double-click the bottom blank box to add a new filter.
+
+Check "Quick Filters > Start Libation with 1st filter Default" to have your top filter automatically applied when Libation starts. In this top example, I want to always start without these: at books I've tagged hidden, books I've tagged as free_audible_originals, and books which I have rated.
