 Besu must connect with other peers to sync with the network. If your node is having trouble peering, 
 try [troubleshooting peering](../../how-to/troubleshoot/peering.md).
 
+Besu supports several synchronization options for different network types and use cases:
+
+### Public network syncing
+
+For public networks, Besu offers the following sync modes:
+
+- [Snap synchronization](#snap-synchronization)
+- [Checkpoint synchronization](#checkpoint-synchronization)
+- [Fast synchronization](#fast-synchronization)
+- [Full synchronization](#run-an-archive-node)
+
+### Private network syncing
+
+For private, permissioned blockchain networks, Besu uses the same synchronization modes as public networks, but with specific configurations for private network needs.
+
+When setting up a private network, consider the following:
+
+- Use the same sync modes as public networks (snap, checkpoint, fast, or full sync).
+- Configure the network with a custom genesis file.
+- Set the network ID and bootnode(s) specific to your private network.
+- Implement permissioning features to control network access.
+
+Choose the appropriate sync mode based on your private network's requirements and node purposes.
+
+:::note
+When configuring syncing for a private network, ensure all nodes use compatible sync modes and configurations.
