@@ -112,7 +112,8 @@ We also release a script and Dockerfile for building PaddlePaddle docker images
 across different cuda versions. To build these docker images, run:
 
 ```bash
-REPO=[your_repo_name] bash ./build_docker_images.sh
+bash ./build_docker_images.sh
+docker build -t [REPO]/paddle:tag -f [generated_docker_file] .
