+
+## Installing the chart
+
+```console
+helm repo add parity https://paritytech.github.io/helm-charts/
+helm install polkadot parity/polkadot
+```
+
+This will deploy a single Polkadot node with the default configuration, using a pruned database snapshot for fast setup.
+
+### Public database snapshots
+
+You can use public database snapshots from [snapshots.polkadot.io](https://snapshots.polkadot.io/), eg:
+
+- https://snapshots.polkadot.io/polkadot-paritydb-prune
+- https://snapshots.polkadot.io/polkadot-rocksdb-prune
+- https://snapshots.polkadot.io/polkadot-rocksdb-archive
+- https://snapshots.polkadot.io/kusama-paritydb-prune
+- https://snapshots.polkadot.io/kusama-rocksdb-prune
+- https://snapshots.polkadot.io/kusama-rocksdb-archive
+- https://snapshots.polkadot.io/westend-paritydb-archive
+- https://snapshots.polkadot.io/westend-paritydb-prune
+- https://snapshots.polkadot.io/westend-rocksdb-prune
+- https://snapshots.polkadot.io/westend-rocksdb-archive
+- https://snapshots.polkadot.io/westend-collectives-rocksdb-archive
+
+For example, to restore a Kusama pruned node ParityDB database from a snapshot, use the following chart values:
+```yaml
+node:
+    node:
+      chain: kusama
+      chainData:
+        chainSnapshot:
+          enabled: true
+          url: https://snapshots.polkadot.io/kusama-paritydb-prune
+        pruning: 256
+```
+
+Polkadot and Kusama backups are pruned at 256 blocks. Westend backups are pruned at 1000 blocks.
+
+### Resizing the node disk

+Refer to the ["Resizing the node disk section" of the node chart](https://github.com/paritytech/helm-charts/tree/main/charts/node#resizing-the-node-disk).
+
+### Optional Vault Integration
