+> [!WARNING]
+> ## Breaking Changes
+> * The docker image now runs as user 1001 and group 1001. Make sure that the permissions on your volumes allow user 1001 to read and write to them or see the User section below for other options, or if you're not sure.
+> * `SLEEP_TIME` is now set to `-1` by default. This means the image will run once and exit. If you were relying on the previous default, you'll need to explicitly set the `SLEEP_TIME` environment variable to `30m` to replicate the previous behavior.
+> * The docker image now ignores the values in `Settings.json` for `Books` and `InProgress`. You can now change the folder that books are saved to by using the `LIBATION_BOOKS_DIR` environment variable.
 
-### Disclaimer
+# Disclaimer
 The docker image is provided as-is. We hope it can be useful to you but it is not officially supported.
 
-### Setup
+### Configuration
-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.
+Configuration in Libation is handled by two files, `AccountsSettings.json` and `Settings.json`. These files can usually be found in the Libation folder in your user's home directory. The easiest way to configure these is to run the desktop version of Libation and then copy them into a folder, such as `/opt/libation/config`, that you'll volume mount into the image. `Settings.json` is technically optional, and, if not provided, Libation will run using the default settings. Additionally, the `Books` and `InProgress` settings in `Settings.json` will be ignored and the image will instead substitute it's own values.
-
-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.
+Once the configuration files are copied, the docker image can be run with the following command.

-  rmcrackan/libation

+### Environment Variables
+| Env Var  | Default | Description |
+| -------- | ------- | ----------- |
+| SLEEP_TIME  | -1 | Length of time to sleep before doing another scan/download. Set to -1 to run one. |
+| LIBATION_BOOKS_DIR | /data | Folder where books will be saved |
+| LIBATION_CONFIG_DIR | /config | Folder to read configuration from. |
+| LIBATION_DB_DIR    | /db | Optional folder to load database from. If not mounted, will load database from `LIBATION_CONFIG_DIR`. |
+| LIBATION_DB_FILE | | Name of database file to load. By default it will look for all `.db` files and load one if there is only one present. |
+| LIBATION_CREATE_DB | true | Whether or not the image should create a database file if none are found. |
+
+### User
+This docker image runs as user `1001`. In order for the image to function properly, user `1001` must be able to read and write the volumes that are mounted in. If they are not, you will see errors, including [sqlite error](#1060), [Microsoft.Data.Sqlite.SqliteException](#1110), [unable to open database file](#1113), [Microsoft.EntityFrameworkCore.DbUpdateException](#1049)
+
+If you're not sure what your user number is, check the output of the `id` command. Docker should normally run with the number of the user who configured and ran it.
+
+If you want to change the user the image runs as, you can specify `-u <uid>:<gid>`. For example, to run it as user `2000` and group `3000`, you could do the following:
+
+```
+sudo docker run -d \
+  -u 2000:3000 \
+  -v /opt/libation/config:/config \
+  -v /opt/libation/books:/data \
+  --name libation \
+  --restart=always \
+  rmcrackan/libation:latest
+```
+
+If the user it's running as is correct, and it still cannot write, be sure to check whether the files and/or folders might be owned by the wrong user. You can use the `chown` command to change the owner of the file to the correct user and group number, for example: `chown -R 1001:1001 /mnt/audiobooks /mnt/libation-config`
+
+### Advanced Database Options
+The docker image supports an optional database mount location defined by `LIBATION_DB_DIR`. This allows the database to be mounted as read/write, while allowing the rest of the configuration files to be mounted as read only. This is specifically useful if running in Kubernetes where you can use Configmaps and Secrets to define the configuration. If the `LIBATION_DB_DIR` is mounted, it will be used, otherwise it will look for the database in `LIBATION_CONFIG_DIR`. If it does not find the database in the expected location, it will attempt to make an empty database there.

+# Frequently Asked Questions
+
+## Q: What's the difference between 'Classic' and 'Chardonnay'?
+
+**A:** First and most importantly: Classic and Chardonnay have the exact same features.
+
+* **Classic** is Windows only. Its older 'grey boxes' look has a compact design which allows for more information on the screen. Notably, Classic was written using an older, more mature technology which has built-in support for screenreaders.
+
+* **Chardonnay** is available for Windows, Mac, and Linux. Its modern design has a more open look and feel.
+
+## Q: Now that I've downloaded my books, how can I listen to them?
+
+**A:** You can use any app which plays m4b files (or mp3 files if you used that setting). Here are just a few ideas. Disclaimer: I have no affiliation with any of these companies:
+
+* iOS: [BookPlayer](https://apps.apple.com/us/app/bookplayer/id1138219998)

+* [plex](https://www.plex.tv/). Listen with [Prologue](https://prologue.audio/) (iOS)
+
+## Q: I'm having trouble loggin into my Brazil account.
+
+For reasons known only to Jeff Bezos and God, amazon and audible brazil handle logins slightly differently. [See this ticket for more details.](https://github.com/rmcrackan/Libation/issues/1103)
+
+## Q: How do I use Libation with a South Africa account?
+
+**A:** Like many countries, amazon gives South Africa it's own amazon site. [Unlike many other regions](https://www.audible.com/ep/country-selector) there is not South Africa specific audible site. Use `US` for your region -- ie: audible.com.

 - Move the extracted Libation app bundle to your applications folder.
-- Open a terminal (Go > Utilities > Terminal)
+- Right-click on Libation and then click on open
-- Copy/paste/run the following command (you'll be prompted to enter your password)
+- The first time, it will not immediately show you an option to open it. Just dismiss the dialog and do the same thing again (right-click -> open) then you will get an option to run the unsigned application. This takes about 10 seconds.

+
+  ```Console
+  xattr -r -d com.apple.quarantine ~/Downloads/Libation.app

+
+From: [How to Open Anyway](https://support.apple.com/guide/mac-help/apple-cant-check-app-for-malicious-software-mchleab3a043/mac):
+
+* On your Mac, choose Apple menu > System Settings, then click Privacy & Security in the sidebar. (You may need to scroll down.)
+* Go to Security, then click Open.
+* Click Open Anyway. This button is available for about an hour after you try to open the app.
+* Enter your login password, then click OK.
+
+## Troubleshooting
+
+If Libation fails to start after completing the above steps, try the following:
+
+1. Right-click the Libation app in your applications folder and select _Show Package Contents_
+2. Open the `Contents` folder and then the `MacOS` folder.
+3. Find the file named `Libation`, right-click it, and then select _Open_.
