**Interface Reference** lets you declare interface-typed fields and assign implementors in the Unity Inspector. Unity cannot serialize a plain `IMyInterface` field. This package gives you a typed field and an **Implementor Picker** so you can assign:

* **Unity Objects** — `MonoBehaviour` or `ScriptableObject` that implement the interface
* **References** — plain serializable classes or structs via `SerializeReference`

## Who this is for

You write interface-based code and want to pick the concrete implementor in the Inspector — without writing a custom property drawer.

## How to learn this package

1. [Installation](/interface-reference/installation.md) — add the package from the Asset Store
2. [Quick Start](/interface-reference/quick-start.md) — declare a field, open the picker, assign, use the value in code
3. [Picker Window](/interface-reference/features/picker-window.md) — search, Unity Object vs Reference, Scene / Assets filters
4. [API](/interface-reference/reference/api.md) — `Value`, helpers, and type variants
