Installing

Minecraft	1.21.1
Loader	NeoForge 21.1.256 or later
Required	ProgressiveStages 3
Recommended	Patchouli, Legendary Tabs

1. Install NeoForge for 1.21.1.
2. Put foreverpathways-<version>.jar and ProgressiveStages in your mods folder.
3. Add the other mods you want. The more of them, the bigger the tree.
4. Do the same on the server. The mod must be installed on the server and on every client.
5. Start the game once, then restart it. The first launch writes the stage files and adjusts config; the restart applies them.

Note

On first run the mod also adjusts two other mods' configs, only where a value is still at that mod's default, and logs exactly what it changed: ProgressiveStages' block interaction switches, and Hardcore Torches' burn times and lantern lighting.
