+    import       Import payload signed with genesis secret key and create & import a genesis certificate
+```
+
+Run 'genesis bootstrap' command in release with default configuration, **only in test mode**.
+This allows the Mithril Aggregator node to bootstrap a `Genesis Certificate`. After this operation, the Mithril Aggregator will be able to produce new snapshots and certificates.
+
+```bash
+./mithril-aggregator genesis bootstrap
+```
+
+Or with a specific `Genesis Secret Key`, **only in test mode**.
+
+```bash
+./mithril-aggregator genesis bootstrap --genesis-secret-key **YOUR_SECRET_KEY*
+```
+
+Run 'genesis export' command in release with default configuration.
+This allows the Mithril Aggregator node to export the `Genesis Payload` that needs to be signed (and later reimported) of the `Genesis Certificate`. The signature of the `Genesis Payload` must be done manually with the owner of the `Genesis Secret Key`.
+
+```bash
+./mithril-aggregator genesis export
+```
+
+Or with a custom export path (to override the default value `./mithril-genesis-payload.txt`)
+
+```bash
+./mithril-aggregator genesis export --target-path **YOUR_TARGET_PATH**
+```
+
+Run 'genesis import' command in release with default configuration.
+This allows the Mithril Aggregator node to import the signed payload of the `Genesis Certificate` and create it in the store. After this operation, the Mithril Aggregator will be able to produce new snapshots and certificates.
+
+```bash
+./mithril-aggregator genesis import
+```
+
+Or with a custom export path (to override the default value `./mithril-genesis-signed-payload.txt`)
+
+```bash
+./mithril-aggregator genesis import --signed-payload-path **YOUR_SIGNED_PAYLOAD_PATH**
+```
