 For example, consider the domain name `node.example.com`, which resolves to a `nwaku` node:

 Nodes with a domain name and secure WebSocket configured will generate a discoverable ENR with `/wss` multiaddr and `/dns4` domain name, essential for verifying domain certificates when connecting securely.

+## Configure Store Protocol and Message Store
+
+To enable `nwaku` to be a [store service node](/overview/concepts/protocols#store), use the following configuration options:
+
+- `store`: Enables `Waku Store` protocol on the node (disabled by default).
+- `store-message-retention-policy`: Retention policy of the store node (how long messages will be persisted). Two different retention policies are supported:
+	- Time retention policy: `time:<duration-in-seconds>` (e.g., `time:14400`)
+	- Capacity retention policy: `capacity:<messages-count>` (e.g, `capacity:25000`)
+	- Set this option to an empty string to disable the retention policy.
+- `store-message-db-url`: Database connection URL for persisting messages in the [SQLAlchemy database URL format](https://docs.sqlalchemy.org/en/20/core/engines.html#database-urls). Setting this option to an empty string will instruct the node to use the fallback in-memory message store.
+
+```bash
+./build/wakunode2 \
+  --store=true \
+  --store-message-retention-policy=[MESSAGE RETENTION POLICY] \
+  --store-message-db-url=[DATABASE CONNECTION URL]
+```
+
+For example, consider a `nwaku` node that is configured to be a `Store` protocol and retain messages received in the last `15,000` seconds:
+
+```bash
+./build/wakunode2 \
+  --store=true \
+  --store-message-retention-policy=time:15000 \
+  --store-message-db-url=sqlite://store.sqlite3
+```
+
+You can configure `nwaku` as a `Waku Store` client using the `storenode` option. This allows the node to query peers for historical messages but not store any message itself.
+
+```bash
+./build/wakunode2 --storenode=[STORE PEER MULTIADDR]
+```
+
+For example, consider a `nwaku` node that does not persist messages but can query peers for historical messages:
+
+```bash
+./build/wakunode2 --storenode=/dns4/node-01.ac-cn-hongkong-c.wakuv2.prod.statusim.net/tcp/30303/p2p/16Uiu2HAm4v86W3bmT1BiH6oSPzcsSr24iDQpSN5Qa992BCjjwgrD
