+
+## Creating Traits
+
+To create an trait, you first need to make a class overriding `CustomTrait`.  
+Example:
+
+```csharp
+using COTL_API.CustomTraits;
+using UnityEngine;
+using System.IO;
+```
+
+```csharp
+[HarmonyPatch]
+internal class ExampleTrait : CustomTrait
+     {
+         public override string InternalName => "ExampleTrait";
+
+         public override bool Positive => true;
+
+        // exclusive traits are traits that can't appear along with this trait!
+        // if they are also custom defined trait, you only need to exclude it on 
+        // one of the traits.
+         public override List<FollowerTrait.TraitType> ExclusiveTraits =>
+         [
+             FollowerTrait.TraitType.RoyalPooper
+         ];
+
+         public override TraitFlags TraitFlags => TraitFlags.RareStartingTrait;
+
+         public override string LocalizedTitle() => "Example Trait";
+
+         public override string LocalizedDescription() => "this trait is just an example :).";
+
+         public override Sprite Icon => TextureHelper.CreateSpriteFromPath(Path.Combine(Plugin.PluginPath, "Assets", "ExampleTrait.png"));
+
+        // by default, no behaviour for custom traits is added. use patches check in 
+        // your own code for the presence of the trait, and change the game's 
+        // behvaiour accordingly.
+         [HarmonyPatch(typeof(FollowerBrain), nameof(FollowerBrain.GetPoopType))]
+         [HarmonyPrefix]
+         private static bool FollowerBrain_GetPoopType(ref FollowerBrain __instance, ref StructureBrain.TYPES __result)
+         {
+             if (!__instance.Info.Traits.Contains(Plugin.ExampleTrait)) return true;
+
+             __result = StructureBrain.TYPES.POOP_RAINBOW;
+             DataManager.Instance.DaySinceLastSpecialPoop = TimeManager.CurrentDay;
+             return false;
+
+         }
+}
+```
+
+There is no diffrence between cult traits and regular traits. Cult traits are added by `FollowerTrait.AddCultTrait(FollowerTrait.TraitType);` and regular ones by `followerBrain.AddTrait(FollowerTrait.TraitType);` on a follower's brain.
+
+`CustomTrait` supports the following overrides:
+| Type | Name | Default |
+|-|-|-|
+| string | InternalName | \[REQUIRED\] |
+|bool|Positive| true|
+|bool|IsTraitUnavailable()|false|
+|Sprite|Icon|TextureHelper.CreateSpriteFromPath(PluginPaths.ResolveAssetPath("placeholder.png"));|
+|List<FollowerTrait.TraitType>| ExclusiveTraits|[]|
+TraitFlags|TraitFlags|TraitFlags.None|
+|string|LocalizedTitle()|LocalizationManager.GetTranslation($"Traits/{ModPrefix}.{InternalName}")|
+|string|LocalizedDescription()|LocalizationManager.GetTranslation($"Traits/{InternalName}.description")|
+
+## Adding Traits
+
+To add a trait to the game, simply use `CustomTraitManager.Add()`.  
+Example:
+
+```csharp
+using COTL_API.CustomTraits;
+public static FollowerTrait.TraitType ExampleTrait { get; private set; }
+```
+
+```csharp
+private void Awake()
+{
+    ExampleTrait = CustomTraitManager.Add(new ExampleTrait());
+}
+```
+
+Assigning the result of `CustomTraitManager.Add()` allows you to reference that trait elsewhere in your code using `Plugin.ExampleTrait`.
+
+## Final Steps
+
+For the icon to load, you need to put it in the appropriate location. For the example, this would be `/Assets/ExampleTrait.png` relative to the root folder containing the .dll  
+Directory structure:
+
+```
+📂plugins
+ ┣📂Assets
+ ┃ ┗🖼️ExampleTrait.png
+ ┗📜mod_name.dll
+```
