 # Appendix I: Understanding Bitcoin Standup
 
-[§2.1: Setting Up a Bitcoin Core VPS with StackScript](02_1_Setting_Up_a_Bitcoin-Core_VPS_with_StackScript.md) explains the process of creating a Bitcoin node using [Bitcoin-Standup-Scripts](https://github.com/BlockchainCommons/Bitcoin-Standup-Scripts). The following appendix explains what the major sections of the script do. You may wish to following along in [Linode Standup](https://github.com/BlockchainCommons/Bitcoin-Standup-Scripts/blob/master/Scripts/LinodeStandUp.sh) in another window.

 ## Conclusion — Understanding Bitcoin Standup
 
-Bitcoin Standup uses scripts to try and match much of the functionality of a [GordianNode](https://github.com/BlockchainCommons/GordianNode-macOS). It should provide you with a secure Bitcoin environment with a foundation of Bitcoin Core and Tor for RPC communications.
