 # Joining the latest testnet
 
 Depending on whether you are a genesis validator, you can join the latest testnet either as a genesis validator or as a full node.
 
 ## Joining as a genesis validator
-Joining the testnet validator is identical to that of a mainnet validator.
 
-For this reason, please refer to [these docs](../../operators/validators/validator-setup.mdx#start-validating).
+In order to join the network as a genesis validator, you will need to have been selected in the genesis ceremony. If you have not been selected, you can still join as a full node.
+If you have been selected. You must run the following command:
+
+```bash
+CHAIN_ID="<chain-id>"
+VALIDATOR_ALIAS="<your-validator-alias>"
+namadac utils join-network --chain-id $CHAIN_ID --genesis-validator $VALIDATOR_ALIAS
+```
+
+<Callout>
+Note that if you use the above command, your pre-genesis wallet must be in the default base directory (`$BASE_DIR`). If the wallet is not in the default base directory, you must use the flag `--pre-genesis-path` instead. The value for this will be `$BASE_DIR/pre-genesis/$VALIDATOR_ALIAS`.
+
+E.g if your base directory is `.namada` and your validator alias is `my-validator`, then run the command 
+
+```bash
+CHAIN_ID="<chain-id>"
+VALIDATOR_ALIAS="my-validator"
+BASE_DIR=".namada"
+namadac utils join-network --chain-id $CHAIN_ID --pre-genesis-path $BASE_DIR/pre-genesis/$VALIDATOR_ALIAS
+```
+</Callout>
+
+Running the node of a pre-genesis validator is identical to that of a mainnet validator.
+
+For this reason, please refer to [these docs](../../operators/validators/validator-setup.mdx#start-validating) for running the node.
 
 ## Joining as a full node
 If you are not a genesis validator, please follow the steps for [joining as a full node](../../operators/ledger/running-a-full-node.mdx).

 ```shell copy
 namadan ledger run
+# or for more verbose output:
+# NAMADA_LOG=info CMT_LOG_LEVEL=p2p:none,pex:error NAMADA_CMT_STDOUT=true namadan ledger run

 The ledger will then use the validator consensus key to sign blocks, should your validator account acquire enough voting power to be included in the active validator set. The size of the active validator set is limited to `128` (the limit is set by the PoS `max_validator_slots` parameter).
