-To reset the development environment completely, remove all volumes plus the

+#### Minio / remoteStorage
 
-    docker compose down -v
-    rm -f db/*.sqlite3 tmp/.setup-complete
-    docker compose up --build
+If you want to run remoteStorage accounts locally, you will have to create the
+respective bucket first. With the `minio` container running (run by default
+when using Docker Compose), follow these steps:
 
-#### Garage / remoteStorage
-
-remoteStorage accounts use the `garage` S3-compatible object store. On first
-start, Garage automatically configures a single-node cluster and creates the
-`remotestorage` bucket together with a `dev-key1` access key (secret
-`1234567890123456`), so no manual setup is required.
-
-If you want to run remoteStorage accounts locally, the `garage` container is
-started by default when using Docker Compose. To run just the remoteStorage
-stack:
-
-* `docker compose up web redis garage liquor-cabinet`
-
-The S3 API is available at http://localhost:3900 (region `garage`). If you want
-to start over with a fresh storage, delete the `garage-data` volume as well as
-the container.
-
-#### Accessing remoteStorage from another machine
-
-remoteStorage clients force HTTPS for any host except `localhost`, and browsers
-block plain-HTTP requests to a LAN IP as mixed content. To connect to the dev
-remoteStorage from a browser on another machine (including production apps such
-as Inspektor), forward the ports over SSH and connect as `localhost`:
-
-    ssh -N -L 3000:localhost:3000 -L 4567:localhost:4567 <user>@<dev-host>
-
-Then use `<user>@localhost:3000` as the remoteStorage address in the client.
-WeFinger discovery and storage requests are served through the forwarded ports,
-so no TLS setup is needed.
+* `docker compose up web redis minio liquor-cabinet`
+* Head to http://localhost:9001 and log in with user `minioadmin`, password
+  `minioadmin`
+* Create a new bucket called `remotestorage` (or whatever you
+  change the `S3_BUCKET` config to)
+* Create a new key with ID "dev-key" and secret "123456789" (or whatever you
+  change `S3_ACCESS_KEY` and `S3_SECRET_KEY` to). Leave the policy field empty,
+  as it will automatically allow access to the bucket you created.
