Below are a few examples of what you might see, and what the mod can do.
First-time setup
The first time you reach the main menu, a short setup opens and walks through level scaling, the star range and its spawn chances, the distance rings, creature health and damage, modifiers, raids, boss night spawns, the Nemesis system and Location Reset. You can save from any page, or click the X to skip it. Either way it won't open again, in this or any other mod manager profile: whether you have seen it is kept once per user, in ModQuickConfig/FirstRun.cfg next to your Valheim saves (%USERPROFILE%\AppData\LocalLow\IronGate\Valheim on Windows). Set FirstTimeSetup to ShowNextLaunch in the BepInEx config to see it again, or to Never to keep it closed in that profile. The same pages (without the welcome page) open from the Mod Config button on the main menu, or on the pause menu for hosts and admins. Each page has a Reset page button that puts just that page back to the mod's defaults; like any other edit, nothing is written until you Save. If a config file has a mistake that stops it loading, saving from the panel replaces it, but first keeps a copy next to it as <file>.invalid.<date>.bak, so you can see what was wrong and copy your settings back.
Upgrading rather than installing fresh? The setup stays out of your way: a config file that already exists when this version first runs means the mod has been configured already, so it is marked done without being shown.
Other mods that share the Mod Config button can have a welcome of their own. They open one at a time, in turn, rather than on top of each other.
Features
Levels, Levels and more Levels (LevelSettings.yaml)
So you want creatures to have more levels, but you don't want to die instantly to a level 100 boar when you start the game? Well have I got the config file for you.
Level settings allows configuration of creature levelup chance, creature stats, max level, increased level up chance based on distance from the center- and respectively biome based configs for all of that.

Biome Configuration
Lets take a look at some of the things you can do with this, and what better spot to start out than the default All biome configuration (which applies to every creature by default).
