+# How to use Misskey with Docker
+Ensure that the working directory is the repository root directory.
+
+To create misskey image:
+`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`
+
+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`
+
+Note that $(pwd) is the working directory.
