 ## Prerequisites
 
-Archive node requires a pre-existing oasis-node state.
+Running an archive node requires a pre-existing `oasis-node` state. If you don't have one,
+you can download a snapshot of a specific network state [here][snapshots].
 
-## Configuration
+[snapshots]: https://snapshots.oasis.io
 
-Archive mode can be enabled by using the `mode` setting.
+## Configuration (Oasis Core 23 and later)
+
+Starting from the Oasis Core version 23, the configuration for enabling archive mode has changed.
+Use the `mode` setting:

+## Configuration (Oasis Core 22 and earlier)
+
+For all pre-Eden networks, such as Damask, the configuration remains the same but requires the
+appropriate version of `oasis-node` and the node state.
+
+#### Damask
+
+To run an archive node for Damask, use [Oasis Core v22.2.12] and the following
+configuration:
+
+```yaml
+datadir: /node/data
+
+log:
+  level:
+    default: info
+    tendermint: info
+    tendermint/context: error
+  format: JSON
+
+genesis:
+  file: /node/etc/genesis.json
+
+consensus:
+  tendermint:
+    mode: archive
+
+runtime:
+  mode: client
+  paths:
+    # Paths to ParaTime bundles for all of the supported ParaTimes.
+    - "{{ runtime_orc_path }}"
+```
+
+#### Cobalt
+
+To run an archive node for Cobalt, use [Oasis Core v21.3.14] and the following configuration:
+
+```yaml
+log:
+  level:
+    default: info
+    tendermint: info
+    tendermint/context: error
+  format: JSON
+
+genesis:
+  file: /node/etc/genesis.json
+
+consensus:
+  tendermint:
+    mode: archive
+
+runtime:
+  supported:
+    - "{{ runtime_id }}"
+
+  paths:
+    "{{ runtime_id }}": {{ paratime_binary_path }}
+
+worker:
+  storage:
+    enabled: true
+```
+
+:::warn
+
+Ensure you are using the correct version of oasis-node and the pre-existing state for your specific pre-Eden network.
