 ## Summary
 
 You run one playbook and set up a node. For example:
 
 ```bash
-ansible-playbook -i inventory juno_full_setup.yml -e "target=juno_testnet"
+ansible-playbook -i inventory juno.yml -e "target=juno_testnet"
 ```
 
 But before you rush with this easy setup, you probably want to read on so you understand the structure of this Ansible program and all the features it offers.

+Needless to say, you need to update the dummy values in the inventory file. For each node, you need to update the server IP, validator_name and log_name (log_name is optional if you do not install Promtail). While you are free to keep the default, you might also want to update:

 2. ansible_port: The sample file assumes `22`. But if you are like me, you will have a different ssh port other than `22` to avoid port sniffing.
 3. ansible_ssh_private_key_file: The sample file assumes `~/.ssh/id_rsa`, but you might have a different key location.

 It is beyond the scope of this guide to help you create a sudo user, alternate ssh port, create a private key, install Ansible on your machine, etc. You can do a quick online search and find the answers. In my experience, Digital Ocean have some quality guides on these topics. Stack Overflow can help you trouble-shoot if you are stuck.

+## Additional Info
+
+When you install a node that has upgrades in the past, you can either sync from Block 1, or use a snapshot to time travel. We strongly recommend snapshots, which will save you time of syncing and debugging. Here are a list of trusted snapshot providers. Do your own research and make sure that you can trust the snapshot providers
