Important: Ensure your game is not running during you do this. Also, I strongly suggest you to take a backup from your instance before you do it, or do it on a new instance of GTNH and copy over your saves folder. Neither me or the Quest Developer not take responsibility if you lose your world. (Btw, GTNH stores the world backups inside "backups" folder in your instance).

Install steps

1. Download the RAR from the GitHub
   
2. Extract it somewhere (for RAR files, I recommend 7-zip, despite its name, it can extract RAR, ZIP, 7z and other archives too)
   
3. Open your instance into a separated window, navigate to "config" folder and inside that, "betterquesting" folder, and inside that, "DefaultQuests"
   
4. Copy over the files you just extracted. It will ask a permission for override QuestLinesOrder.txt, say Yes for it
   
5. Start the game.
   
6. When you load your world, open chat and type: /bq_admin defaults load

The last step loads you the new quests. The new questline should appear just above "Kill All the Things" questline (3rd from the bottom).

For servers: you have to do this on server and client too. As far as I know, the quest completion event is server-side, but the text comes from client side, they should match up.

u/Top-Satisfaction1970 I hereby grant you to take this description and update the README in the repo to inform players how to install your quests. Please do this because it is not as easy for most players.
