Java stable route
Use CurseForge's Install action from the Verity JE project. Its app can create a compatible profile or add the mod to an existing one. Confirm the profile says Minecraft 1.20.1 and Forge before launch.
Bedrock route
Download only from the chosen maintainer project, open the .mcaddon in Minecraft, apply its behavior/resource packs, enable Beta APIs if required, and test in a copied world. Project-specific connect steps must come from that project's tutorial.
Success signals
A successful install is more than a launch without a crash. Verify that the selected project appears in the mod or pack list, the target world loads, Verity's documented entry behavior occurs, and AI setup succeeds without exposing a key.
