+## Ping
+
+The Ping service is now published in its own package.
+
+**Before**
+
+```ts
+import { createLibp2p } from 'libp2p'
+import { pingService } from 'libp2p/ping'
+
+const node = await createLibp2p({
+  services: {
+    ping: pingService()
+  }
+})
+```
+
+**After**
+
+```ts
+import { createLibp2p } from 'libp2p'
+import { ping } from '@libp2p/ping'
+
+const node = await createLibp2p({
+  services: {
+    ping: ping()
+  }
+})
+```
+
 ## KeyChain
 
 The KeyChain object is no longer included on Libp2p and must be instantiated explicitly if desired.
