 # ZongzeLi/ckpts
 
-This repository is initialized by a script.
+This repository hosts grouped model checkpoints uploaded by an automated script.
 
-- Root contains standard files so the model page is not empty.
-- You can edit this README.md in the web UI or via CLI.
+Directory layout:
+- For `xiao/rewardflow`: only `global_step_100/` directories are uploaded.
+- For `xuan/ckpts`: for each checkpoint, the maximum `global_step_*/` directory is uploaded.
+
+Paths are preserved relative to their sources, e.g.:
+`verl_agent_alfworld/rewardflow_qwen2.5_7b_decay_True_seed_0_v5_gamma0.95/global_step_100/...`
+
+Notes:
+- Some auxiliary files (logs, visualizations, caches) may be excluded by ignore patterns.
+- Uploads may be performed in parallel and per-file to improve progress visibility.
