-A single-user, javascript app to scrobble your recent plays to [Maloja](https://github.com/krateng/maloja) (and other clients, eventually)
+A javascript app to scrobble music you listened to, to [Maloja](https://github.com/krateng/maloja), [Last.fm](https://www.last.fm), and [ListenBrainz](https://listenbrainz.org)

-* Displays running status and buffered log through web server
-* Spotify - Authorize your app through the web server
-* Spotify - Persists obtained credentials to file

+* Monitor status of Sources and Clients using [webhooks (Gotify or Ntfy)](/docs/configuration.md#webhook-configurations) or [healthcheck endpoint](/docs/configuration.md#health-endpoint)
+* Supports configuring for single or multiple users (scrobbling for your friends and family!)
+* Web server interface for stats, basic control, and detailed logs
+* Smart handling of credentials (persistent, authorization through app)
+* Easy configuration through ENVs or JSON
+* Docker images for x86/ARM
+
+**Why should I use this over a browser extension and/or mobile app scrobbler?**
+
+* **Platform independent** -- Because multi-scrobbler communicates directly with service APIs it will scrobble everything you play regardless of where you play it. No more need for apps on every platform you use!
+* **Open-source** -- Get peace of mind knowing exactly how your personal data is being handled.
+* **Track your activity regardless of where you listen** -- Scrobble from many Sources to one Client with ease and without duplicating tracks.
+* **Manage scrobbling for others** -- Scrobble for your friends and family without any setup on their part. Easily silo sources to specific clients to keep plays separate.
+
+**But I already scrobble my music to Last.fm/ListenBrainz, is multi-scrobbler for me?**
+
+Yes! You can use [Last.fm as a **Source**](/docs/configuration.md#lastfm--source-) or [Listenbrainz as a **Source**](/docs/configuration.md#listenbrainz--source-) to forward scrobbles from your profile to any other Client! That way you can keep your current scrobble setup as-is but still get the benefit of capturing your data to a self-hosted location.
+
+<img src="/assets/status-ui.jpg" width="800">
+
+## How Does multi-scrobbler (MS) Work?
+
+You set up configurations for one or more **Sources** and one or more **Clients**. MS monitors all of your configured **Sources**. When new tracks are played by a Source it grabs that information and then sends it (scrobbles it) to all **Clients** that Source is configured to scrobble to.
+
+### Source
+
+A **Source** is a data source that contains information about tracks you are playing like a music player or platform. Examples are **Spotify, Jellyfin, Plex, Youtube Music, Airsonic**, etc...
+
+Source configurations consist of:
+
+* A friendly name.
+* Any data needed to communicate or authenticate with the Source.
+* An optional list of Client names that the Source should scrobble to. If omitted the Source also scrobbles to all configured Clients.
+
+### Client
+
+A **Client** is an application that stores the historical information about what songs you have played (scrobbles). Examples are **Maloja, Last.fm, Listenbrainz**...
+
+Client configurations consist of:
+
+* A friendly name.
+* Any data needed to communicate or authenticate with the Client.

 ## Installation

+[See the **Installation** documentation](/docs/installation.md)

-### Locally
+## Configuration

-Clone this repository somewhere and then install from the working directory
-
-```bash
-npm install
-```
-
-### [Dockerhub](https://hub.docker.com/repository/docker/foxxmd/multi-scrobbler)
-
-```
-foxxmd/multi-scrobbler:latest
-```
-
-## Setup
-
-All configuration is done through json files or environment variables. Reference the [examples in the config folder](config) more detailed explanations and structure.
-
-**A property from a json config will override the corresponding environmental variable.**
-
-### App (General)
-
-[JSON config example](config/config.json.example)
-
-These environmental variables do not have a config file equivalent (to make Docker configuration easier)
-
-| Environmental Variable | Required? |   Default    |                                        Description                                        |
-|----------------------------|-----------|--------------|-------------------------------------------------------------------------------------------|
-| `CONFIG_DIR`               |         - | `CWD/config` | Directory to look for all other configuration files                                       |
-| `LOG_PATH`                 |         - | `CWD/logs`   | If `false` no logs will be written. If `string` will be the directory logs are written to |
-| `PORT`                     |         - | 9078         | Port to run web server on                                                                 |
-
-**The app must have permission to write to `CONFIG_DIR` in order to store the current spotify access token.**
-
-
-### Sources (Where Music Plays Come From)
-
-#### Spotify
-
-To access your Spotify history you must [register an application](https://developer.spotify.com/dashboard) to get a Client ID/Secret. Make sure to also whitelist your redirect URI in the application settings.
-
-[Spotify config example](config/spotify.json.example)
-
-All variables have a config file equivalent which will overwrite the ENV variable if present (so config file is not required if ENVs present)
-
-| Environmental Variable     | Required? |            Default             |                    Description                     |
-|----------------------------|-----------|----------------------------------|----------------------------------------------------|
-| `SPOTIFY_CLIENT_ID`        | Yes       |                                  |                                                    |
-| `SPOTIFY_CLIENT_SECRET`    | Yes       |                                  |                                                    |
-| `SPOTIFY_ACCESS_TOKEN`     | -         |                                  | Must include either this token or client id/secret |
-| `SPOTIFY_REFRESH_TOKEN`    | -         |                                  |                                                    |
-| `SPOTIFY_REDIRECT_URI`     | -         | `http://localhost:{PORT}/callback` | URI must end in `callback`                         |
-
-The app will automatically obtain new access/refresh token if needed and possible. These will override values from configuration.
-
-#### [Plex](https://plex.tv)
-
-Check the [instructions](docs/plex.md) on how to setup a [webhooks](https://support.plex.tv/articles/115002267687-webhooks) to scrobble your plays.
-
-[Plex config example](config/plex.json.example)
-
-| Environmental Variable | Required | Default |                   Description                   |
-|------------------------|----------|---------|-------------------------------------------------|
-| PLEX_USER              |        - |         | The username of the user to scrobble tracks for. No user specified means all tracks by all users will be scrobbled. |
-
-#### [Tautulli](https://tautulli.com)
-
-Check the [instructions](docs/plex.md) on how to setup a notification agent to scrobble your plays.
-
-**Environmental variables and config file is the same as Plex**
-
-### Scrobble Clients
-
-At least one client (the only one right now...) must be setup in order for the app to work. Client configurations can alternatively be configured in the main [`config.json`](https://github.com/FoxxMD/multi-scrobbler/blob/master/config/config.json.example) configuration
-
-#### Maloja
-
-[Maloja config example](config/maloja.json.example)
-
-All variables have a config file equivalent which will overwrite the ENV variable if present (so config file is not required if ENVs present)
-
-| Environmental Variable | Required? | Default |          Description          |
-|----------------------------|-----------|---------|-------------------------------|
-| `MALOJA_URL`               | Yes       |         | Base URL of your installation |
-| `MALOJA_API_KEY`           | Yes       |         | Api Key                       |
+[See the **Configuration** documentation](/docs/configuration.md)

+## Plex/Tautulli/Jellyfin don't connect
+
+These three [sources](/README.md#source) are **ingress-based** which means that multi-scrobbler waits for the Plex/Tautulli/Jellyfin server to contact multi-scrobbler, as opposed to multi-scrobbler contacting the server.
+
+multi-scrobbler will log information about any server that connects to it for these three services. In the logs it looks something like this:
+
+```
+2023-02-22T10:55:56-05:00 info   : [Ingress - Plex  ] Received request from a new remote address: ::ffff:192.168.0.140 (UA: PlexMediaServer/1.24.5.5173-8dcc73a59)
+2023-02-22T10:55:56-05:00 info   : [Ingress - Plex  ] ::ffff:192.168.0.140 (UA: PlexMediaServer/1.24.5.5173-8dcc73a59) Received valid data from server examplePlex for the first time.
+2023-02-22T10:55:56-05:00 warn   : [Plex Request    ] Received valid Plex webhook payload but no Plex sources are configured
+```
+It also logs if a server tries to connect to a URL that it does not recognize:
+
+```
+2023-02-22T11:16:12-05:00 debug  : [App             ] Server received POST request from ::ffff:192.168.0.140 (UA: PlexMediaServer/1.24.5.5173-8dcc73a59) to unknown route: /plkex
+```
+**So, if you do not see either of these in your logs then Plex/Tautulli/Jellyfin is not able to connect to your multi-scrobbler instance at all.**
+
+This is not something multi-scrobbler can fix and means you have an issue in your network.
+
+### Troubleshooting

+Check or try all these steps before submitting an issue:
+
+#### Turn on Debug Logging
+
+First, turn on **debug** logging for multi-scrobbler by setting the environmental variable `LOG_LEVEL=debug`:
+
+* using node `LOG_LEVEL=debug ... node src/index.js`
+* using docker `docker run -e LOG_LEVEL=debug ... foxxmd/multi-scrobbler`
+
+Check the output for any additional information.
+
+#### Check Host name and URL
+
+The URLs examples in the [configuration](/docs/configuration.md) documentation assume you are running Plex/Tautulli/Jellyfin on the same server as multi-scrobbler. If these are not the same machine then you need to determine the IP address or domain name that multi-scrobbler is reachable at and use that instead of `localhost` when configuring these sources. **This is likely the same host name that you would use to access the web interface for multi-scrobbler.**
+
+EX `http://localhost:9078/plex` -> `http://192.168.0.140:9078/plex`
+
+#### Check Firewall and Port Forwarding
+
+If the machine multi-scrobbler is running on has a firewall ensure that port **9078** is open. Or if it is in another network entirely make sure your router is forwarding this port and it is open to the correct machine.
+
+#### Check Source Service Logs
+
+Plex/Tautulli/Jellyfin all have logs that will log if they cannot connect to multi-scrobbler. Check these for further information.
+
+##### Plex
+
+Settings -> Manage -> Console
+
+##### Tautulli
+
+Check the command-line output of the application or docker logs.
+
+##### Jellyfin
+
+Administration -> Dashboard -> Advanced -> Logs
+
+## Jellyfin has warnings about undefined or missing data
+
+Make sure you have 
+* [Configured the webhook plugin correctly](/docs/configuration.md#jellyfin)
+  * Checked the **Send All Properties(ignores template)** option in the webhook settings and **Saved**
+
+multi-scrobbler is known to work on Jellyfin `10.8.9` with Webhook version `11.0.0.0`.
+
+You can verify the payload sent from the webhook by modifying your jellyfin configuration to include `logPayload: true` which will output the raw payload to DEBUG level logging:
+
+```json
+[
+  {
+    "name": "MyJellyfin",
+    "clients": [],
+    "data": {
+      "users": ["FoxxMD"],
+      "options": {
+        "logPayload": true
+      }
+    }
+  }
+]
+```
+
+If your issue persists and you open an Issue for it please include the raw payload logs in your report.
+
+
+## Spotify/Deezer/LastFM won't authenticate
+
+Ensure any **client id** or **secrets** are correct in your configuration.
+
+The callback/redirect URL for these services must be:
+
+* the same address you would use to access the multi-scrobbler web interface
+  * the web-interface must be accessible from the browser you are completing authentication from.
+
+If multi-scrobbler is not running on the same machine your browser is on then the default/example addresses (`http://localhost...`) **will not work.** You must determine the address you can reach the web interface at (such as `http://192.168.0.140:9078`) then use that in place of `localhost` in the callback URLs.
+
+EX `http://localhost:9078/lastfm/callback` -> `http://192.168.0.220:9078/lastfm/callback`
+
+# Configuration Issues
+
+## Config could not be parsed
+
+If you see something like this in your logs:
+
+```
+2023-02-19T10:05:42-06:00 warn   : [App] App config file exists but could not be parsed!
+2023-02-19T10:05:42-06:00 error  : [App] Exited with uncaught error
+2023-02-19T10:05:42-06:00 error  : [App] Error: config.json could not be parsed
+```
+
+It means the JSON in your configuration file is not valid. Copy and paste your configuration into a site like [JSONLint](https://jsonlint.com/) to find out where errors you have and fix them.

+# Configuration Overview
+
+[**Sources** and **Clients**](/README.md#how-does-multi-scrobbler-ms-work) are configured using environmental (ENV) variables and/or json files.
+
+**MS will parse configuration from both configuration types.** You can mix and match configurations but it is generally better to stick to one or the other.
+
+TIP: Check the [**FAQ**](/docs/FAQ.md) if you have any issues after configuration!
+
+## ENV-Based Configuration
+
+This is done by passing environmental variables and so does not require any files to run MS.
+
+* Using a docker container EX `docker run -e "SPOTIFY_CLIENT_ID=yourId" -e "SPOTIFY_CLIENT_SECRET=yourSecret" ...`
+* Using a local installations by exporting variables before running MS EX `SPOTIFY_CLIENT_ID=yourId SPOTIFY_CLIENT_SECRET=yourSecret node index.js`
+
+Use ENV-based configuration if:
+
+* You are the only person for whom MS is scrobbling for
+* You have a very simple setup for MS such as one scrobble [Client](/README.md#client) and one [Source](/README.md#source) IE Plex -> Maloja
+
+## File-Based Configuration
+
+MS will parse configuration files located in the directory specified by the `CONFIG_DIR` environmental variable. This variable defaults to:
+
+* Local installation -> `PROJECT_DIR/config`
+* Docker -> `/config` (in the container) -- see the [install docs](/docs/installation.md#docker) for how to configure this correctly
+
+Use File-based configuration if:
+
+* You have many [Sources](/README.md#source)
+* You have many of each type of **Source** you want to scrobble from IE 2x Plex accounts, 3x Spotify accounts, 1x
+  Funkwhale...
+* You have more than one scrobble **Client** you want to scrobble to IE multiple Maloja servers
+* You want only some **Sources** to scrobble to some **Clients** IE Fred's Spotify account scrobbles to Fred's Maloja
+    server, but not Mary's Maloja server
+
+File-based configurations located in the `CONFIG_DIR` directory can be parsed from
+
+* an **all-in-one** config file named `config.json` that contains information for all Sources and Clients and/or
+* many **specific** files named based on the client/source to configure IE `plex.json` `spotify.json`
+
+There are **example configurations** for all Source/Client types and AIO config located in the [/config](/config) directory of this project. These can be used as-is by renaming them to `.json`.
+For docker installations these examples are copied to your configuration directory on first-time use.
+
+There is also a [**kitchensink example**](/docs/kitchensink.md) that provides examples of using all sources/clients in a complex configuration.
+
+### All-in-One File Configuration
+
+[**Explore the schema for this configuration, along with an example generator and validator, here**](https://json-schema.app/view/%23?url=https%3A%2F%2Fraw.githubusercontent.com%2FFoxxMD%2Fmulti-scrobbler%2Fdevelop%2Fsrc%2Fcommon%2Fschema%2Faio.json)
+
+Example directory structure:
+
+```
+/CONFIG_DIR
+  config.json
+```
+
+<details>
+<summary>Config Example</summary>
+
+```json5
+// in config.json
+{
+  //...
+  "sources": [
+    {
+      "name": "myConfig",
+      "type": "spotify",
+      "clients": [
+        "myMalojaClient"
+      ],
+      "data": {
+        "clientId": "anExample"
+        //...

+        // ...
+      }
+    }
+  ]
+}
+```
+
+</details>
+
+`config.json` can also be used to set default behavior for all sources/clients using `sourceDefaults` and `clientDefaults` properties.
+
+See [config.json.example](/config/config.json.example) for an annotated example or check out [the kitchen sink example](kitchensink.md).

+
+**Known Issues:**
+* "Time played at" is somewhat inaccurate since the api only reports "played X minutes ago" so...
+  * All scrobble times are therefore "on the minute" and you may experience occasional duplicate scrobbles
+  * "played X minutes ago" sometimes is also not reported correctly
+* Multiple artists are reported as one value and cannot be separated

+## [Youtube Music](https://music.youtube.com)
+
+Credentials for YT Music are obtained from a browser request to https://music.youtube.com **once you are logged in.** [Specific requirements are here and summarized below:](https://github.com/nickp10/youtube-music-ts-api/blob/master/DOCUMENTATION.md#authenticate)
+
+* Open a new tab
+* Open the developer tools (Ctrl-Shift-I) and select the “Network” tab 
+* Go to https://music.youtube.com and ensure you are logged in 
+
+Then...
+
+1. Find and select an authenticated POST request. The simplest way is to filter by /browse using the search bar of the developer tools. If you don’t see the request, try scrolling down a bit or clicking on the library button in the top bar.
+2. **Make sure **Headers** pane is selected and open
+3. In the **Request Headers** section find and copy the **entire value** found after `Cookie:` and use this as the `cookie` value in your multi-scrobbler config
+4. If present, in the **Request Headers** section find and copy the number found in `X-google-AuthUser` and use this as the value for `authUser` in your multi-scrobbler config
+
+![Google Headers](/docs/google-header.jpg)
+
+NOTES:
+
+* YT Music authentication is "browser based" which means your credentials may expire after a (long?) period of time OR if you log out of https://music.youtube.com. In the event this happens just repeat the steps above to get new credentials.
+* Communication to YT Music is **unofficial** and not supported or endorsed by Google. This means that **this integration may stop working at any time** if Google decides to change how YT Music works in the browser.

+
+## [MPRIS](https://specifications.freedesktop.org/mpris-spec/latest/)
+
+MPRIS is a standard interface for communicating with Music Players on **linux operating systems.**
+
+If you run Linux and have a notification tray that shows what media you are listening to, you likely have access to MPRIS.
+
+![Notification Tray](/assets/mpris.jpg)
+
+multi-scrobbler can listen to this interface and scrobble tracks played by **any media player** that communicates to the operating system with MPRIS.
+
+**NOTE:** multi-scrobbler needs to be running as a [**Local Installation**](/docs/installation.md#local) in order to use MPRIS. This cannot be used from docker.

+## [Mopidy](https://mopidy.com/)
+
+Mopidy is a headless music server that supports playing music from many [standard and non-standard sources such as Pandora, Bandcamp, and Tunein.](https://mopidy.com/ext/)
+
+multi-scrobbler can scrobble tracks played from any Mopidy backend source, regardless of where you listen to them.

+
+Configuration Options:
+
+##### `url`
+
+The URL used to connect to the Mopidy server. You MUST have [Mopidy-HTTP extension](https://mopidy.com/ext/http) enabled.
+
+If no `url` is provided a default is used which assumes Mopidy is installed on the same server as multi-scrobbler: `ws://localhost:6680/mopidy/ws/`
+
+Make sure the hostname and port number match what is found in the Mopidy configuration file `mopidy.conf`:
+
+```
+...
+
+[http]
+hostname = localhost
+port = 6680
+
+...
+```
+
+The URL used to connect ultimately must be formed like this: `[protocol]://[hostname]:[port]/[path]`
+If any part of this URL is missing multi-scrobbler will use a default value, for your convenience. This also means that if any part of your URL is **not** standard you must explicitly define it.

+

+
+
+#### URI Blacklist/Whitelist
+
+If you wish to disallow or only allow scrobbling from some sources played through Mopidy you can specify these using `uriBlacklist` or `uriWhitelist` in your config. multi-scrobbler will check the list to see if any string matches the START of the `uri` on a track. If whitelist is used then blacklist is ignored. All strings are case-insensitive.
+
+EX:
+
+```json
+{
+  "uriBlacklist": ["soundcloud"]
+}
+```
+
+Will prevent multi-scrobbler from scrobbling any Mopidy track that start with a `uri` like `soundcloud:song:MySong-1234`
+
+#### Album Blacklist
+
+For certain sources (Soundcloud) Mopidy does not have all track info (Album) and will instead use "Soundcloud" as the Album name. You can prevent multi-scrobbler from using this bad Album data by adding the fake Album name to this list. Multi-scrobbler will still scrobble the track, just without the bad data. All strings are case-insensitive.
+
+EX:
+
+```json
+{
+  "albumBlacklist": ["SoundCloud", "Mixcloud"]
+}
+```
+
+If a track would be scrobbled like `Album: Soundcloud, Track: My Cool Track, Artist: A Cool Artist` 
+then multi-scrobbler will instead scrobble  `Track: My Cool Track, Artist: A Cool Artist`
+
+## [JRiver](https://jriver.com/)
+
+In order for multi-scrobbler to communicate with JRiver you must have [Web Server Interface](https://wiki.jriver.com/index.php/Web_Service_Interface#Documentation_of_Functions) enabled. This can can be in the JRiver GUI:
+
+* Tools -> Options -> Media Network
+  * Check `Use Media Network to share this library...`
+  * If you have `Authentication` checked you will need to provide the **Username** and **Password** in the ENV/File configuration below.
+
+#### URL
+
+If you do not provide a URL then a default is used which assumes JRiver is installed on the same server as multi-scrobbler: `http://localhost:52199/MCWS/v1/`
+
+* Make sure the port number matches what is found in `Advanced` section in the [Media Network](#jriver) options.
+* If your installation is on the same machine but you cannot connect using `localhost` try `0.0.0.0` instead.
+
+The URL used to connect ultimately must be formed like this: `[protocol]://[hostname]:[port]/[path]`
+If any part of this URL is missing multi-scrobbler will use a default value, for your convenience. This also means that if any part of your URL is **not** standard you must explicitly define it.

+# Monitoring
+
+multi-scrobbler supports some common webhooks and a healthcheck endpoint in order to monitor Sources and Clients for errors.
+
+## Webhook Configurations
+
+Webhooks will **push** a notification to your configured servers on these events:
+
+* Source polling started 
+* Source polling retry
+* Source polling stopped on error 
+* Scrobble client scrobble failure
+
+Webhooks are configured in the main [config.json](#all-in-one-file-configuration) file under the `webhook` top-level property. Multiple webhooks may be configured for each webhook type. EX:
+
+```json
+{
+  "sources": [
+    ...
+  ],
+  "clients": [
+    ...
+  ],
+  "webhooks": [
+    {
+      "name": "FirstGotifyServer",
+      "type": "gotify",
+      "url": "http://192.168.0.100:8070",
+      "token": "abcd"
+    }, 
+    {
+      "name": "SecondGotifyServer",
+      "type": "gotify",
+      ...
+    },
+    {
+      "name": "NtfyServerOne",
+      "type": "ntfy",
+      ...
+    },
+    ...
+  ]
+}
+```
+
+### [Gotify](https://gotify.net/)
+
+Refer to the [config schema for GotifyConfig](https://json-schema.app/view/%23/%23%2Fdefinitions%2FGotifyConfig?url=https%3A%2F%2Fraw.githubusercontent.com%2FFoxxMD%2Fmulti-scrobbler%2Fdevelop%2Fsrc%2Fcommon%2Fschema%2Faio.json)
+
+multi-scrobbler optionally supports setting message notification priority via `info` `warn` and `error` mappings.
+
+EX
+
+```json
+{
+  "type": "gotify",
+  "name": "MyGotifyFriendlyNameForLogs",
+  "url": "http://192.168.0.100:8070",

+  "priorities": {
+    "info": 3,
+    "warn": 4,
+    "error": 5
+  }
+}
+```
+
+## Health Endpoint
+
+An endpoint for monitoring the health of sources/clients is available at GET `http://YourMultiScrobblerDomain/health`
+
+* Returns `200 OK` when **everything** is working or `500 Internal Server Error` if **anything** is not 
+* The plain url (`/health`) aggregates status of **all clients/sources** -- so any failing client/source will make status return 500 
+  * Use query params `type` or `name` to restrict client/sources aggregated IE `/health?type=spotify` or `/health?name=MyMaloja`
+* On 500 the response returns a JSON payload with `messages` array that describes any issues
+  * For any clients/sources that require authentication `/health` will return 500 if they are **not authenticated** 
+  * For sources that poll (spotify, yt music, subsonic) `/health` will 500 if they are **not polling**

-# Minimal Configuration
-
-Examples assume you have registered a Spotify application with the default callback url of `http://localhost:9078/callback`.
-
-If you use another callback url or domain name you will need to specify at a minimum `SPOTIFY_REDIRECT_URI`.

+# Installation
+
+## Local
+
+Clone this repository somewhere and then install from the working directory
+
+```bash
+git clone https://github.com/FoxxMD/multi-scrobbler.git .
+cd multi-scrobbler
+nvm use # optional, to set correct Node version
+npm install
+npm build
+npm start
+```
+
+### Local Usage Examples
+
+* The web UI is served on port `9078`. This can be modified using the `PORT` environmental variable.
+
+#### Using [file-based](/docs/configuration.md#file-based-configuration) configuration
+
+```bash
+npm start
+```
+
+#### Using [env-based](/docs/configuration.md#env-based-configuration) configuration
+
+```bash
+SPOTIFY_CLIENT_ID=yourId SPOTIFY_CLIENT_SECRET=yourSecret MALOJA_URL="http://domain.tld" node src/index.js
+```
+
+## [Docker](https://hub.docker.com/r/foxxmd/multi-scrobbler)
+
+Cross-platform images are built for x86 (Intel/AMD) and ARM (IE Raspberry Pi)
+
+```
+foxxmd/multi-scrobbler:latest
+```
+
+Or use the provided [docker-compose.yml](/docker-compose.yml) after modifying it to fit your configuration.
+
+Recommended configuration steps for docker or docker-compose usage:
+
+* If you must **bind a host directory into the container for storing configurations and credentials:**
+    * [Using `-v` method for docker](https://docs.docker.com/storage/bind-mounts/#start-a-container-with-a-bind-mount): `-v /path/on/host/config:/config`
+    * [Using docker-compose](https://docs.docker.com/compose/compose-file/compose-file-v3/#short-syntax-3): `- /path/on/host/config:/config`
+* (Optionally) map the web UI port in the container **9078** to the host
+    * With [docker](https://docs.docker.com/engine/reference/commandline/run/#publish): `-p 9078:9078` (first port is the port on the host to use)
+    * With [docker-compose](https://docs.docker.com/compose/compose-file/compose-file-v3/#short-syntax-1): `- "9078:9078"`
+* (Optionally) set the [timezone](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) for the container using the environmental variable `TZ` ([docker](https://docs.docker.com/engine/reference/commandline/run/#env)) ([docker-compose](https://docs.docker.com/compose/compose-file/compose-file-v3/#environment))
+
+### Linux Host
+
+If you are
+
+* using [rootless containers with Podman](https://developers.redhat.com/blog/2020/09/25/rootless-containers-with-podman-the-basics#why_podman_)
+* running docker on MacOS or Windows
+
+this **DOES NOT** apply to you.
+
+If you are running Docker on a **Linux Host** you must specify `user:group` permissions of the user who owns the **configuration directory** on the host to avoid [docker file permission problems.](https://ikriv.com/blog/?p=4698) These can be specified using the [environmental variables **PUID** and **PGID**.](https://docs.linuxserver.io/general/understanding-puid-and-pgid)
+
+To get the UID and GID for the current user run these commands from a terminal:
+
+* `id -u` -- prints UID
+* `id -g` -- prints GID
+
+### Docker Usage Examples
+
+#### Using [env-based](/docs/configuration.md#env-based-configuration) configuration
+
+```bash
+docker run -e "SPOTIFY_CLIENT_ID=yourId" -e "SPOTIFY_CLIENT_SECRET=yourSecret" -e "MALOJA_URL=http://domain.tld" -e "MALOJA_API_KEY=1234" -e "PUID=1000" -e "PGID=1000" -p 9078:9078 -v /path/on/host/config:/config foxxmd/multi-scrobbler

+# Example Config using all Possible Features
+
+Scenario: 
+
+* You want to scrobble plays for yourself (Foxx), Fred, and Mary
+* Each person has their own Maloja server
+* Each person has their own Spotify account
+* You have your own Airsonic (subsonic) server you to scrobble from
+* You have your own Youtube Music account you want to scrobble from
+* Mary has her own Last.fm account she also wants to scrobble to
+* Fred has his own Spotify application and provides you with just his access and refresh token because he doesn't trust you (wtf Fred)
+* Fred has a Plex server and wants to scrobble everything he plays
+* Mary uses Fred's Plex server but only wants to scrobble her plays from the `podcast` library
+* The three of you have a shared library on Plex called `party` that you only play when you are hanging out. You want plays from that library to be scrobbled to everyone's servers.
+* Fred also has his own Jellyfin server and wants to scrobble everything he plays
