 ## Adding the Repository
 
 ```sh
-helm repo add taskchampion https://gothenburgbitfactory.org/taskchampion-sync-server/helm-chart
+helm repo add taskchampion https://gothenburgbitfactory.org/taskchampion-sync-server
 helm repo update
 ```
 
-## Installing the Chart
-
-The chart requires exactly one storage backend to be enabled. To install with
-the SQLite backend:
+## Installing
 
 ```sh
+# SQLite backend
 helm install taskchampion-sync-server taskchampion/taskchampion-sync-server \
   --set sqlite.enabled=true
-```
 
-To install with the Postgres backend, provide the connection details:
-
-```sh
+# PostgreSQL backend
 helm install taskchampion-sync-server taskchampion/taskchampion-sync-server \
   --set postgres.enabled=true \
   --set postgres.host=my-postgres \
-  --set postgres.database=taskchampion \
+  --set postgres.db=taskchampion \
   --set postgres.username=myuser \
   --set postgres.password=mypassword
 ```
 
-Alternatively, pass an existing Secret name via `postgres.existingSecret`. The
-secret must contain a `connection` key holding a [LibPQ-style connection
-URI](https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNSTRING-URIS).
+## Storage Backends
 
-## Configuration
+Exactly one storage backend must be enabled. The chart fails validation if
+neither or both are enabled.
 
-The chart does not implement TLS. The expectation is that a Kubernetes ingress
-or gateway will terminate TLS and proxy HTTP traffic to the server container.
-Enable one of the built-in options or configure your own:
+### SQLite
 
-```sh
-# NGINX ingress
---set ingress.enabled=true --set ingress.hosts[0]=taskchampion.example.com
+Mounts a volume at `sqlite.dataDir` (default `/var/lib/taskchampion-sync-server/data`).
+The volume defaults to `emptyDir` but can be backed by a PVC or
+existing PersistentVolumeClaim:
 
-# Gateway API HTTPRoute
---set httpRoute.enabled=true \
---set httpRoute.gateway=my-gateway \
---set httpRoute.host=taskchampion.example.com
+| Value | Description |
+|-------|-------------|
+| `sqlite.persistence.enabled` | Create a PVC (default: `false`) |
+| `sqlite.existingPV` | Use an existing PVC by name |
+| `sqlite.emptyDir` | emptyDir volume settings (default fallback) |
+
+### PostgreSQL
+
+Creates a Deployment with optional replicas, an auto-generated or existing
+secret for the connection string, and an init container that waits for
+PostgreSQL, applies the schema, and optionally seeds client IDs.
+
+**Secret handling** — When `postgres.existingSecret` is empty (default), the
+chart creates a secret named `{release-name}-connection` with a `conn` key.
+When set, the chart reads the named secret. It accepts either a `conn` key
+with a full [LibPQ-style URI](https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNSTRING-URIS)
+or individual fields (`host`, `port`, `username`, `password`, `database`) that
+override the corresponding `postgres.*` values.
+
+**Init container** — Enabled by default. Waits for PG readiness, downloads
+the schema from `https://raw.githubusercontent.com/GothenburgBitFactory/taskchampion-sync-server/v0.7.0/postgres/schema.sql`,
+applies it, and seeds client IDs if `clientIdSecret` is set. Override the
+schema URL with `postgres.initContainer.schemaUrl`.
+
+**Replicas** — Replicas only apply with PostgreSQL:
+`replicas.enabled=true`, `replicas.count=N`. SQLite is always single-replica.
+
+## Secrets
+
+### Client ID Secret
+
+Optional. Restrict which client IDs the server accepts. Create a Secret with
+comma-separated UUIDs (base64-encoded) under a `client-ids` key:
+
+```yaml
+apiVersion: v1
+kind: Secret
+metadata:
+  name: my-client-ids
+type: Opaque
+data:
+  client-ids: <base64-encoded comma-separated UUIDs>
 ```
 
-To restrict which client IDs the server accepts, create a Secret containing a
-newline-separated list of UUIDs and reference it:
+Reference it via `clientIdSecret: "my-client-ids"`. The value is available to
+the server as `CLIENT_ID` and to the init container as `CLIENT_IDS`.
 
-```sh
---set clientIdSecret=my-client-ids-secret
+## Networking
+
+The chart does not implement TLS. Terminate TLS at the ingress or gateway and
+proxy HTTP to port 8080.
+
+### Ingress (NGINX)
+
+```yaml
+ingress:
+  enabled: true
+  hosts:
+    - taskchampion.example.com
 ```
 
-See the chart's `values.yaml` for the full set of configuration options.
+### HTTPRoute (Kubernetes Gateway API)
+
+Use `parentRefs`, `hostnames`, and `rules`:
+
+```yaml
+httpRoute:
+  enabled: true
+  parentRefs:
+    - name: my-gateway
+  hostnames:
+    - tasks.example.com
+  rules:
+    - path:
+        type: PathPrefix
+        value: /
+      backendPort: 8080
+```
+
+The deprecated fields `httpRoute.gateway`, `httpRoute.host`,
+`httpRoute.path`, and `httpRoute.port` are used as a fallback when the
+structured arrays are empty.
+
+### ServiceAccount and RBAC
+
+When `serviceAccount.create` is `true` (default), the chart creates a
+ServiceAccount, a Role with `get`/`create`/`update`/`patch` on secrets, and
+a RoleBinding. Set `serviceAccount.name` to use an existing SA.
+
+## Reference
+
+See the chart's [values.yaml](https://github.com/GothenburgBitFactory/taskchampion-sync-server/blob/main/helm/taskchampion-sync-server/values.yaml)
