Add model card and metadata

Hi, I'm Niels from the Hugging Face community science team.

I've opened this pull request to improve the model card for the **Garment Particles** project. This PR adds relevant metadata (pipeline tag and license) and provides a structured description including links to the paper, project page, and the official code repository. I have also included sample usage commands for inference as documented in the GitHub README.

This helps make the model more discoverable and easier to use for the community.

+# Garment Particles: A 2D–3D Symmetric Garment Representation for Generation and Editing
+
+Official checkpoints for **Garment Particles**, a framework for garment design spanning intuitive creation from high-level intent (text, image, sketch) to complex low-level editing across 2D sewing patterns and 3D draped geometry.

+- **Project Page**: [https://garment-particles.github.io](https://garment-particles.github.io)

+## Overview
+Garment Particles uses a 5D point-cloud representation to jointly encode 2D sewing patterns and 3D geometry. This representation enables Garment Particles Flow (GPF), a rectified flow framework that supports intuitive generation from high-level inputs (text, images, sketches) and various editing operations on 2D sewing patterns and 3D geometries.
+
+## Installation
+To use these checkpoints, clone the [official repository](https://github.com/garment-particles/GarmentParticles) and install the dependencies:
+
+```bash
+conda create -n interact_garment python=3.10
+conda activate interact_garment
+pip install torch torchvision
+pip install -r src/requirements.txt
+export PYTHONPATH=$PWD/src:$PYTHONPATH
+```
+
+## Sample Usage (Inference)
+
+Download the checkpoints into `src/checkpoints/` and run the inference script from the `src` directory.
