@@ -5,75 +5,35 @@ PluralKit is a Discord bot meant for plural communities. It has features like me
 
 PluralKit has a Discord server for support, feedback, and discussion: https://discord.gg/PczBt78 
 
-# Requirements
-Running the bot requires [.NET 5](https://dotnet.microsoft.com/download), a PostgreSQL database and a Redis database. It should function on any system where the prerequisites are set up (including Windows).
-
-Optionally, it can integrate with [Sentry](https://sentry.io/welcome/) for error reporting and [InfluxDB](https://www.influxdata.com/products/influxdb-overview/) for aggregate statistics.
-
-# Configuration
-Configuring the bot is done through a JSON configuration file. An example of the configuration format can be seen in [`pluralkit.conf.example`](https://github.com/PluralKit/PluralKit/blob/master/pluralkit.conf.example).
-The configuration file needs to be placed in the bot's working directory (usually the repository root) and must be called `pluralkit.conf`.
-
-The configuration file is in JSON format (albeit with a `.conf` extension). The following keys are available (using `.` to indicate a nested object level), bolded key names are required:
-* **`PluralKit.Bot.Token`**: the Discord bot token to connect with
-* **`PluralKit.Database`**: the URI of the database to connect to (in [ADO.NET Npgsql format](https://www.connectionstrings.com/npgsql/))
-* **`PluralKit.RedisAddr`**: the `host:port` of a Redis database to connect to
-* `PluralKit.Bot.Prefixes`: an array of command prefixes to use (default `["pk;", "pk!"]`).
-* **`PluralKit.Bot.ClientId`**: the ID of the bot's user account, used for calculating the bot's own permissions and for the link in `pk;invite`.
-* `PluralKit.SentryUrl` *(optional)*: the [Sentry](https://sentry.io/welcome/) client key/DSN to report runtime errors to. If absent, disables Sentry integration.
-* `PluralKit.InfluxUrl` *(optional)*: the URL to an [InfluxDB](https://www.influxdata.com/products/influxdb-overview/) server to report aggregate statistics to. An example of these stats can be seen on [the public stats page](https://stats.pluralkit.me). 
-* `PluralKit.InfluxDb` *(optional)*: the name of an InfluxDB database to report statistics to. If either this field or `PluralKit.InfluxUrl` are absent, InfluxDB reporting will be disabled.
-* `PluralKit.LogDir` *(optional)*: the directory to save information and error logs to. If left blank, will default to `logs/` in the current working directory.
-
-The bot can also take configuration from environment variables, which will override the values read from the file. Here, use `:` (colon) or `__` (double underscore) as a level separator (eg. `export PluralKit__Bot__Token=foobar123`) as per [ASP.NET config](https://docs.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-3.1#environment-variables).
-
 # Running
+In production, we run PluralKit using Kubernetes. The configuration can be found in the infra repo.
 
-## Docker
-The easiest way to get the bot running is with Docker. The repository contains a `docker-compose.yml` file ready to use.
+For self-hosting, it's simpler to use Docker, with the provided [docker-compose](./docker-compose.yml) file.
 
-* Clone this repository: `git clone https://github.com/PluralKit/PluralKit`
-* Create a `pluralkit.conf` file in the same directory as `docker-compose.yml` containing at least `PluralKit.Bot.Token` and `PluralKit.Bot.ClientId` fields
-  * (`PluralKit.Database` is overridden in `docker-compose.yml` to point to the Postgres container)
-* Build the bot: `docker-compose build`
-* Run the bot: `docker-compose up`
-
-In other words:
+Create a `.env` file with the Discord client ID and bot token:
 ```
-$ git clone https://github.com/PluralKit/PluralKit
-$ cd PluralKit
-$ cp pluralkit.conf.example pluralkit.conf
-$ nano pluralkit.conf  # (or vim, or whatever)
-$ docker-compose up -d
+CLIENT_ID=198622483471925248
+BOT_TOKEN=MTk4NjIyNDgzNDcxOTI1MjQ4.Cl2FMQ.ZnCjm1XVW7vRze4b7Cq4se7kKWs
 ```
 
-## Manually
-* Install the .NET 6 SDK (see https://dotnet.microsoft.com/download)
-* Clone this repository: `git clone https://github.com/PluralKit/PluralKit`
-* Create and fill in a `pluralkit.conf` file in the same directory as `docker-compose.yml`
-* Run the bot: `dotnet run --project PluralKit.Bot`
-  * Alternatively, `dotnet build -c Release -o build/`, then `dotnet build/PluralKit.Bot.dll`
+If you want to use `pk;admin` commands (to raise member limits  and such), set `ADMIN_ROLE` to a Discord role ID:
 
-(tip: use `scripts/run-test-db.sh` to run a temporary PostgreSQL database on your local system. Requires Docker.)
+```
+ADMIN_ROLE=682632767057428509
+```
 
-## Scheduled Tasks worker
+*If you didn't clone the repository with submodules, run `git submodule update --init` first to pull the required submodules.*
+Run `docker compose build`, then `docker compose up -d`.
 
-There is a scheduled tasks worker that needs to be ran separately from the bot. This handles cleaning up the database, and updating statistics (system/member/etc counts, shown in the `pk;stats` embed).
+To view logs, use `docker compose logs`.
 
-Note: This worker is *not required*, and the bot will function correctly without it.
+Postgres data is stored in a `pluralkit_data` [Docker volume](https://docs.docker.com/engine/storage/volumes/).
 
-If you are running the bot via docker-compose, this is set up automatically.
-
-If you run the bot manually you can run the worker as such:
-* `dotnet run --project PluralKit.ScheduledTasks`
-* or if you used `dotnet build` rather than `dotnet run` to run the bot: `dotnet build/PluralKit.ScheduledTasks.dll`
-
-# Upgrading database from legacy version
-If you have an instance of the Python version of the bot (from the `legacy` branch), you may need to take extra database migration steps.
-For more information, see [LEGACYMIGRATE.md](./LEGACYMIGRATE.md).
