How to install the PoD Development branch (Patreon)

From our patron, Dunnlag:

How to install the PoD Development branch:
1 - Signup for the Patreon. Provide the team with your GitHub user name, then download zip from the GitHub link.  
2 - Extract the files from the zip.  
3 - Place the "princesofdarkness.mod" file in your "c:\Users\ [YourUserName]\Documents\Paradox Interactive\Crusader Kings III\mod" folder.  
3b - Place the "princesofdarkness" folder in the same folder from step #3.  
4 - Edit the "devprincesofdarkness.mod" file that was placed in My Documents to replace "YOURUSERNAME" in the path with your account user name on your PC.  
5 -Launch CK3 and get to the Paradox Launcher.  
6 - Beneath the Resume and Play buttons is a dropdown for Playset.  
7  - Add a new playset and select the "Development Princes of Darkness" mod.  
8 - Select that playset and launch the game.  

If your C drive is small/full, it is possible to install the mod into your Steam directory.
Follow steps 1-3 above.
Skip step 3b.
Do not place the large folder in your "My Documents"  
4 - Find your Steam Workshop folder for CK3. It should be something like "c:\ [wherever-steam-is]\steamapps\workshop\content[#####]"
4b - If you have multiple games with workshop content, you may have to open all the folders to figure out which one is for CK3. Mine is number 1158310.  
5 - Place the "devprincesofdarkness" folder from the Zip in your Steam Workshop folder.  
5b - It should be something like: "c:[wherever-steam-is]\steamapps\workshop\content\1158310\devprincesofdarkness"  
6 - Edit the "devprincesofdarkness.mod" file that was placed in My Documents to include the new path for the mod in the Steam Workshop folder.  
6b - The path should be something like "c:/[wherever-steam-is]/steamapps/workshop/content/1158310/devprincesofdarkness" Note the different slashes than Windows normally uses.  
7 - Resume at step #5 in the first section to launch the game.
