+# Zeppelin development environment
+Zeppelin's development environment runs entirely within a Docker container.
+Below you can find instructions for setting up the environment and getting started with development!
+
+**Note:** If you'd just like to run the bot for your own server, see 👉 **[PRODUCTION.md](./PRODUCTION.md)** 👈
+
+## Starting the development environment
+
+### Using VSCode devcontainers
+1. Install Docker
+2. Make a copy of `.env.example` called `.env`
+3. Fill in the missing values in `.env`
+4. In VSCode: Install the `Remote - Containers` plugin
+5. In VSCode: Run `Remote-Containers: Open Folder in Container...` and select the Zeppelin folder
+
+### Using VSCode remote SSH plugin
+1. Install Docker
+2. Make a copy of `.env.example` called `.env`
+3. Fill in the missing values in `.env`
+4. Run `docker compose -f docker-compose.development.yml up` to start the development environment
+5. In VSCode: Install the `Remote - SSH` plugin
+6. In VSCode: Run `Remote-SSH: Connect to Host...`
+    * As the address, use `ubuntu@127.0.0.1:3002` (where `3002` matches `DOCKER_DEV_SSH_PORT` in `.env`)
+    * Use the password specified in `.env` as `DOCKER_DEV_SSH_PASSWORD`
+7. In VSCode: Once connected, click `Open folder...` and select `/home/ubuntu/zeppelin`
+
+### Using JetBrains Gateway
+1. Install Docker
+2. Make a copy of `.env.example` called `.env`
+3. Fill in the missing values in `.env`
+4. Run `docker compose -f docker-compose.development.yml up` to start the development environment
+5. Choose `Connect via SSH` and create a new connection:
+    * Username: `ubuntu`
+    * Host: `127.0.0.1`
+    * Port: `3002` (matching the `DOCKER_DEV_SSH_PORT` value in `.env`)
+6. Click `Check Connection and Continue` and enter the password specified in `.env` as `DOCKER_DEV_SSH_PASSWORD` when asked
+7. In the next pane:
+    * IDE version: WebStorm, PHPStorm, or IntelliJ IDEA
+    * Project directory: `/home/ubuntu/zeppelin`
+8. Click `Download and Start IDE`
+
+### Using any other IDE with SSH development support
+1. Install Docker
+2. Make a copy of `.env.example` called `.env`
+3. Fill in the missing values in `.env`

+# Management
+After starting Zeppelin -- either in the [development](./DEVELOPMENT.md) or [production](./PRODUCTION.md) environment -- you have several tools available to manage it.
+
+## Note
+Make sure to add yourself to the list of staff members (`STAFF`) in `.env` and allow at least one server by default (`DEFAULT_ALLOWED_SERVERS`). Then, invite the bot to the server.
+
+In all examples below, `@Bot` refers to a user mention of the bot user. Make sure to run the commands on a server with the bot, in a channel that the bot can see.
+
+In the command parameters, `<this>` refers to a required parameter (don't include the `< >` symbols) and `[this]` refers to an optional parameter (don't include the `[ ]` symbols). `<this...>` refers to being able to list multiple values, e.g. `value1 value2 value3`.
+
+## Allow a server to invite the bot
+Run the following command:
+```
+@Bot allow_server <serverId> [userId]
+```
+When specifying a user ID, that user will be given "Bot manager" level access to the server's dashboard, allowing them to manage access for other users.
+
+## Disallow a server
+Run the following command:
+```
+@Bot disallow_server <serverId>
+```
+
+## Grant access to a server's dashboard
+Run the following command:
+```
+@Bot add_dashboard_user <serverId> <userId...>
+```
+
+## Remove access to a server's dashboard
+Run the following command:
+```
+@Bot remove_dashboard_user <serverId> <userId...>
+```

+# Zeppelin production environment
+Zeppelin's production environment - that is, the **bot, API, and dashboard** - uses Docker.
+
+## Starting the production environment
+1. Install Docker on the machine running the bot
+2. Make a copy of `.env.example` called `.env`
+3. Fill in the missing values in `.env`
+4. Run `docker compose -f docker-compose.production.yml build`
+5. Run `docker compose -f docker-compose.production.yml up -d`
+
+**Note:** The dashboard and API are exposed with a self-signed certificate. It is recommended to set up a proxy with a proper certificate in front of them. Cloudflare is a popular choice here.
+
+## Updating the bot
+
+### One-click script
+If you've downloaded the bot's files by cloning the git repository, you can use `update.sh` to update the bot.
+
+### Manual instructions
+1. Shut the bot down: `docker compose -f docker-compose.production.yml down`
+2. Update the files (e.g. `git pull`)
+3. Build new images: `docker compose -f docker-compose.production.yml build`
+3. Start the bot again: `docker compose -f docker-compose.production.yml up -d`
+
+### Ephemeral hotfixes
+If you need to make a hotfix to the bot's source files directly on the server:
+1. Shut the bot down: `docker compose -f docker-compose.production.yml down`
+2. Make your edits
+3. Build new images: `docker compose -f docker-compose.production.yml build`
+4. Start the bot again: `docker compose -f docker-compose.production.yml up -d`
+
+Make sure to revert any hotfixes before updating the bot normally.
+
+## View logs
+To view real-time logs, run `docker compose -f docker-compose.production.yml logs -t -f`

 See https://zeppelin.gg/ for more details.

+## Usage documentation
+For information on how to use the bot, see https://zeppelin.gg/docs
+
 ## Development
-These instructions are intended for bot development only.
+See [DEVELOPMENT.md](./DEVELOPMENT.md) for instructions on running the development environment.

-👉 **No support is offered for self-hosting the bot!** 👈
+Once you have the environment up and running, see [MANAGEMENT.md](./MANAGEMENT.md) for how to manage your bot.

-### Running the bot
-1. `cd backend`
-2. `npm ci`
-3. Make a copy of `bot.env.example` called `bot.env`, fill in the values
-4. Run the desired start script:
-    * `npm run build` followed by `npm run start-bot-dev` to run the bot in a **development** environment
-    * `npm run build` followed by `npm run start-bot-prod` to run the bot in a **production** environment
-    * `npm run watch` to watch files and run the **bot and api both** in a **development** environment
-      with automatic restart on file changes
-5. When testing, make sure you have your test server in the `allowed_guilds` table or the guild's config won't be loaded at all
+## Production
+See [PRODUCTION.md](./PRODUCTION.md) for instructions on how to run the bot in production.

-### Running the API server
-1. `cd backend`
-2. `npm ci`
-3. Make a copy of `api.env.example` called `api.env`, fill in the values
-4. Run the desired start script:
-    * `npm run build` followed by `npm run start-api-dev` to run the api in a **development** environment
-    * `npm run build` followed by `npm run start-api-prod` to run the api in a **production** environment
-    * `npm run watch` to watch files and run the **bot and api both** in a **development** environment
-      with automatic restart on file changes
-
-### Running the dashboard
-1. `cd dashboard`
-2. `npm ci`
-3. Make a copy of `.env.example` called `.env`, fill in the values
-4. Run the desired start script:
-    * `npm run build` compiles the dashboard's static files to `dist/` which can then be served with any web server
-    * `npm run watch` runs webpack's dev server that automatically reloads on changes
-
-### Notes
-* Since we now use shared paths in `tsconfig.json`, the compiled files in `backend/dist/` have longer paths, e.g.
-  `backend/dist/backend/src/index.js` instead of `backend/dist/index.js`. This is because the compiled shared files
-  are placed in `backend/dist/shared`.
-* The `backend/register-tsconfig-paths.js` module takes care of registering shared paths from `tsconfig.json` for
-  `ava` and compiled `.js` files
-* To run the tests for the files in the `shared/` directory, you also need to run `npm ci` there
-
-### Config format example
-Configuration is stored in the database in the `configs` table
-
-```yml
-prefix: '!'

-# role id: level
-levels:
-  "12345678": 100 # Example admin
