-This is a fine-grained annotation we collected from SPIN dataset. 
+## Summary
+PartInventory is a fine-grained hierarchical instance-segmentation dataset derived from **SPIN** (built on **PartImageNet**). It provides detailed part annotations and serves as a **proof of concept** for exploring new annotation workflows and more efficient storage formats for large-scale instance segmentation.

+## Description
+PartInventory refines SPIN annotations with more granular labels and updated hierarchies. It is intended to support research on part-level segmentation, hierarchical understanding, and efficient dataset representations (e.g., Parquet/Arrow).  
+
+This release is an early, **proof-of-concept** version. Further expansions are planned.
