 # GRACE
-A novel system for accelerating the reconstruction and overall update process on PMA-based dynamic graph processing systems. GRACE has been integrated into three existing systems: PPCSR(https://github.com/domargan/parallel-packed-csr), Terrace(https://github.com/PASSIONLab/terrace), and VCSR(https://github.com/DIR-LAB/VCSR).
 
-Submission: This paper has been submitted to ICDE26: "GRACE: Alleviating Reconstruction Cost in Dynamic Graph Processing Systems"
+GRACE accelerates reconstruction and update processing in PMA-based dynamic
+graph systems. This repository contains GRACE integrations for
+[PPCSR](https://github.com/domargan/parallel-packed-csr),
+[Terrace](https://github.com/PASSIONLab/terrace), and
+[VCSR](https://github.com/DIR-LAB/VCSR).
 
-# Authors
+## Project status
+
+The paper "GRACE: Alleviating Reconstruction Cost in Dynamic Graph Processing
+Systems" is accepted to ICDE 2026. See the
+[official accepted-paper list](https://icde2026.github.io/accepted-papers.html).
+The repository is a DataSys dynamic-graph research artifact; the three
+integrated systems retain their respective upstream authorship and licenses.
+
+## Implementations
+
+- `PPCSR-GRACE`: PPCSR integration, built by the repository CI.
+- `Terrace-GRACE`: Terrace integration and benchmark scripts.
+- `VCSR-GRACE`: VCSR integration.
