+```
 docker service create \
 --name hexo \
---publish 80:4000 \
--e GIT_EMAIL="me@newnius.com" \
--e GIT_NAME="newnius" \
---mount type=bind,source=/mnt/data/blog,target=/blog \

-docker service create \
---name hexo \
---publish 80:4000 \

+## Notice
+
+_This command creates a docker swarm service, you can use `docker run ...` instead in your way_
+
+_The first time you run this command, it will init the blog and will take some time to install some packages._
+
+_If you live in China, the npm source mirror is blocked and the inititial may not be completed, you can download the required packages and put them where they should be._
