+## ChiaSeeder
+
+### bootstrapPeer
+
+Deprecated in: 0.12.5
+Expected to be removed in: 1.0.0
+
+The `bootstrapPeer` API field was deprecated in favor of `bootstrapPeers`. The latter being the preferred way to specify multiple bootstrap peers for a seeder installation, which still allows for specifying a single peer.
+
+Switch to bootstrapPeers by specifying a yaml string list instead of a string:
+
+```yaml
+spec:
+  chia:
+    # bootstrapPeer: "mainnet-node.chia.svc.cluster.local"
+    bootstrapPeers:
+      - "mainnet-node.chia.svc.cluster.local"
+```
