+## Running local blog using Docker
 
+You can start Hexo server using Docker container with the following command:
+
+```
+$ ./hexo.sh server --config _config.yml,_config.local.yml
+```
+
+It will check if the docker image `eprinstacktraceblog:local` exists, and if not, it will generate one.
+
+```
+$ docker images eprintstacktraceblog:local   
+REPOSITORY             TAG                 IMAGE ID            CREATED             SIZE
