+## Pre-trained Models
+Here are pre-trained models: 
+[ckpt-amr-2.0.tar.gz](https://www.cs.jhu.edu/~s.zhang/data/AMR/ckpt-amr-2.0.tar.gz) 
+and [ckpt-amr-1.0.tar.gz](https://www.cs.jhu.edu/~s.zhang/data/AMR/ckpt-amr-1.0.tar.gz).
+To use them for prediction, simply download & unzip them, and then run **Step 6-8**.
+
+In case that you only need the pre-trained model prediction (i.e., `test.pred.txt`), you can find it in the download.
