+Inspired by [linkding on fly.io](https://github.com/fspoettel/linkding-on-fly)
+
+## Storing the state in s3
+
+You'll an s3 compatible bucket, like backblaze, aws, cloudflare or any compatible provider. Litestream will restore the bucket in an `emptyDir`. Then during operation a `litestream` sidecar will live replicate the changes to s3.
+
+## Contents of `manifest.yaml`
+
+ - a `Namespace` for the project
+ - a `ConfigMap` containing `litestream.yml` config
+     - replace `$S3_ENDPOINT` with your bucket config
+ - a `StatefulSet` containing
+     - an `initContainer` to restore the sqlite db
+     - a `Pod` with `linkding` + `litestream` official images
+ - a `Service` to expose the pods
+     - I'm using tailscale annotations, replace these with traefik or your favorite ingress controller stuff.
+
+## Setup
+
+```
+$ export S3_ENDPOINT=<REPLACE ME>
+$ export S3_BUCKET=<REPLACE ME>
+$ export S3_PATH=<REPLACE ME>
+$ export S3_ACCESS_KEY_ID=<REPLACE ME>
+$ export S3_SECRET_ACCESS_KEY=<REPLACE ME>
+$ envsubst <manifest.yaml | kubectl apply -f -
+$ kubectl create secret -n linkding generic litestream-s3 \
+    --from-literal=LITESTREAM_ACCESS_KEY_ID=$S3_ACCESS_KEY_ID \
+    --from-literal=LITESTREAM_SECRET_ACCESS_KEY=$S3_SECRET_ACCESS_KEY
+```
