# Quickstart

This documentation explains what the Mesh Collider Optimizer is, how to install it, how the optimization + decomposition workflow works, and how to get the best results

## Install from Asset Manager

* Open Unity → **Window → Package Manager → My Assets**.
* Find **Mesh Collider Optimizer** → **Download → Import**.
* The package content (docs, examples, scripts) appears in your Project window.
* Open an example scene to verify everything is working.

## First Optimization (Concave / Non-Convex)

* Add Mesh Collider Optimizer to your object: Add Component → Physics → Mesh Collider Optimizer.
* Keep Convex disabled (best for static objects / kinematic rigidbodies).
* Adjust Quality and Shape Fidelity to balance speed vs accuracy.
* If Auto is enabled, the collider updates as you tweak settings; otherwise press Rebuild for a full pass.

## Quick Batch (Optional)

For fast scene-wide workflow:

* Top menu → Tools → Occlusionn → Mesh Collider Optimizer.
* Use Add Optimizer + Optimize Selected to apply the optimizer to your selection and generate colliders in one step.
