Installation
This is not an installation guide. This is a landing page to ensure that you, the reader, follow the correct installation guide. Realism Overhaul and Realistic Progression One are available for several versions of KSP. Please choose an appropriate link from the list below.
Note: All installation instructions use CKAN as a tool to assist in the installation process. Unless you are intimately familiar with the RO/RP-1 mod ecosystem, you will have a VERY BAD TIME if you insist upon installing without CKAN. If you are unfamiliar with CKAN, it may be informative to read our CKAN 101 article before proceeding.
KSP v1.8.1 (RO/RP-1 v1.4.1) Installation Guide: This is the latest version of KSP for RP-1 supported by the newest RP-1 release (v1.4.1, released April 2020).
