 To create misskey image:
-
-`sudo docker build -t misskey ./docker`
+``` console
+$ sudo docker build -t misskey ./docker
+```
 
 To run misskey:
-
-`sudo docker run --rm -i -t -p $PORT:80 -v $(pwd):/root/misskey -v $DBPATH:/data/db misskey`
+``` console
+$ sudo docker run --rm -i -t -p $PORT:80 -v $(pwd):/root/misskey -v $DBPATH:/data/db misskey
+```
 
 where `$PORT` is the port used to access Misskey Web from host browser
 and `$DBPATH` is the path of MongoDB database on the host for data persistence.
 
-ex: `sudo docker run --rm -i -t -p 80:80 -v $(pwd):/root/misskey -v /data/db:/data/db misskey`
+ex:
+``` console
+$ sudo docker run --rm -i -t -p 80:80 -v $(pwd):/root/misskey -v /data/db:/data/db misskey
+```
 
 If you want to run misskey in production mode, add `--env NODE_ENV=production` like this:
-
-`sudo docker run --rm -i -t -p 80:80 -v $(pwd):/root/misskey -v /data/db:/data/db --env NODE_ENV=production misskey`
+``` console
+$ sudo docker run --rm -i -t -p 80:80 -v $(pwd):/root/misskey -v /data/db:/data/db --env NODE_ENV=production misskey
+```
 
 Note that `$(pwd)` is the working directory.
