-### Interacting with multiple relays
+#### enablePing
+
+You can enable regular pings of connected relays with the `enablePing` option. This will set up a heartbeat that closes the websocket if it doesn't receive a response in time. Some platforms, like Node.js, don't report websocket disconnections due to network issues, and enabling this can increase the reliability of the `onclose` event.

 ```js
 import { SimplePool } from 'nostr-tools/pool'

-const pool = new SimplePool()
+const pool = new SimplePool({ enablePing: true })
+```

-let relays = ['wss://relay.example.com', 'wss://relay.example2.com']
+#### enableReconnect

-let h = pool.subscribeMany(
-  [...relays, 'wss://relay.example3.com'],
-  [
-    {
-      authors: ['32e1827635450ebb3c5a7d12c1f8e7b2b514439ac10a67eef3d9fd9c5c68e245'],
-    },
-  ],
-  {
-    onevent(event) {
-      // this will only be called once the first time the event is received
-      // ...
-    },
-    oneose() {
-      h.close()
-    }
+You can also enable automatic reconnection with the `enableReconnect` option. This will make the pool try to reconnect to relays with an exponential backoff delay if the connection is lost unexpectedly.
+
+```js
+import { SimplePool } from 'nostr-tools/pool'
+
+const pool = new SimplePool({ enableReconnect: true })
+```
+
+Using both `enablePing: true` and `enableReconnect: true` is recommended as it will improve the reliability and timeliness of the reconnection (at the expense of slighly higher bandwidth due to the ping messages).
+
+```js
+// on Node.js
+const pool = new SimplePool({ enablePing: true, enableReconnect: true })
+```
+
+The `enableReconnect` option can also be a callback function which will receive the current subscription filters and should return a new set of filters. This is useful if you want to modify the subscription on reconnect, for example, to update the `since` parameter to fetch only new events.
+
+```js
+const pool = new SimplePool({
+  enableReconnect: (filters) => {
+    const newSince = Math.floor(Date.now() / 1000)
+    return filters.map(filter => ({ ...filter, since: newSince }))
  }

+
+### Connecting to a bunker using NIP-46
+
+`BunkerSigner` allows your application to request signatures and other actions from a remote NIP-46 signer, often called a "bunker". There are two primary ways to establish a connection, depending on whether the client or the bunker initiates the connection.
+
+A local secret key is required for the client to communicate securely with the bunker. This key should generally be persisted for the user's session.
+
+```js
+import { generateSecretKey } from '@nostr/tools/pure'
+
+const localSecretKey = generateSecretKey()
+```
+
+### Method 1: Using a Bunker URI (`bunker://`)
+
+This is the bunker-initiated flow. Your client receives a `bunker://` string or a NIP-05 identifier from the user. You use `BunkerSigner.fromBunker()` to create an instance, which returns immediately. For the **initial connection** with a new bunker, you must explicitly call `await bunker.connect()` to establish the connection and receive authorization.
+
+```js
+import { BunkerSigner, parseBunkerInput } from '@nostr/tools/nip46'
+import { SimplePool } from '@nostr/tools/pool'
+
+// parse a bunker URI
+const bunkerPointer = await parseBunkerInput('bunker://abcd...?relay=wss://relay.example.com')
+if (!bunkerPointer) {
+  throw new Error('Invalid bunker input')
+}
+
+// create the bunker instance
+const pool = new SimplePool()
+const bunker = BunkerSigner.fromBunker(localSecretKey, bunkerPointer, { pool })
+await bunker.connect()
+
+// and use it
+const pubkey = await bunker.getPublicKey()
+const event = await bunker.signEvent({
+  kind: 1,
+  created_at: Math.floor(Date.now() / 1000),
+  tags: [],
+  content: 'Hello from bunker!'
+})
+
+// cleanup
+await signer.close()
+pool.close([])
+```
+> **Note on Reconnecting:** Once a connection has been successfully established and the `BunkerPointer` is stored, you do **not** need to call `await bunker.connect()` on subsequent sessions. 
+
+### Method 2: Using a Client-generated URI (`nostrconnect://`)
+
+This is the client-initiated flow, which generally provides a better user experience for first-time connections (e.g., via QR code). Your client generates a `nostrconnect://` URI and waits for the bunker to connect to it.
+
+`BunkerSigner.fromURI()` is an **asynchronous** method. It returns a `Promise` that resolves only after the bunker has successfully connected. Therefore, the returned signer instance is already fully connected and ready to use, so you **do not** need to call `.connect()` on it.
+
+```js
+import { getPublicKey } from '@nostr/tools/pure'
+import { BunkerSigner, createNostrConnectURI } from '@nostr/tools/nip46'
+import { SimplePool } from '@nostr/tools/pool'
+
+const clientPubkey = getPublicKey(localSecretKey)
+
+// generate a connection URI for the bunker to scan
+const connectionUri = createNostrConnectURI({
+  clientPubkey,
+  relays: ['wss://relay.damus.io', 'wss://relay.primal.net'],
+  secret: 'a-random-secret-string', // A secret to verify the bunker's response
+  name: 'My Awesome App'
+})
+
+// wait for the bunker to connect
+const pool = new SimplePool()
+const signer = await BunkerSigner.fromURI(localSecretKey, connectionUri, { pool })
+
+// and use it
+const pubkey = await signer.getPublicKey()
+const event = await signer.signEvent({
+  kind: 1,
+  created_at: Math.floor(Date.now() / 1000),
+  tags: [],
+  content: 'Hello from a client-initiated connection!'
+})
+
+// cleanup
+await signer.close()
+pool.close([])
+```
+> **Note on Persistence:** This method is ideal for the initial sign-in. To allow users to stay logged in across sessions, you should store the connection details and use `Method 1` for subsequent reconnections. 
+
+### Parsing thread from any note based on NIP-10
+
+```js
+import * as nip10 from '@nostr/tools/nip10'
+
+// event is a nostr event with tags
+const refs = nip10.parse(event)
+
+// get the root event of the thread
+if (refs.root) {
+  console.log('root event:', refs.root.id)
+  console.log('root event relay hints:', refs.root.relays)
+  console.log('root event author:', refs.root.author)
+}
+
+// get the immediate parent being replied to
+if (refs.reply) {
+  console.log('reply to:', refs.reply.id)
+  console.log('reply relay hints:', refs.reply.relays)
+  console.log('reply author:', refs.reply.author)
+}
+
+// get any mentioned events
+for (let mention of refs.mentions) {
+  console.log('mentioned event:', mention.id)
+  console.log('mention relay hints:', mention.relays)
+  console.log('mention author:', mention.author)
+}
+
+// get any quoted events
+for (let quote of refs.quotes) {
+  console.log('quoted event:', quote.id)
+  console.log('quote relay hints:', quote.relays)
+}
+
+// get any referenced profiles
+for (let profile of refs.profiles) {
+  console.log('referenced profile:', profile.pubkey)
+  console.log('profile relay hints:', profile.relays)
 }
