Suggested change
| In addition to primary and secondary nodes, a replica set can include specialized member types: | |

Outdated
| It is possible to add a non-voting node in the edge location through the | ||
| `externalNodes` option. Please see [cross-site replication documentation](replication.md) | ||
| for details. | ||
| Hidden nodes are secondary members that hold a full copy of the data but are not visible to client applications. Hidden always have a 0 priority and therefore, cannot become a primary. But they may vote in primary elections. Read more how the Operator [manages voting members in replica set](#manage-voting-members-in-replica-set). |
