+How to run Kanboard with Docker?
+================================
+
+Kanboard can run easily with [Docker](https://www.docker.com).
+
+The image size is approximately **70MB** and contains:
+
+- [Alpine Linux](http://alpinelinux.org/)
+- The [process manager S6](http://skarnet.org/software/s6/)
+- Nginx
+- PHP 7
+
+The Kanboard cronjob is also running everyday at midnight.
+URL rewriting is enabled in the included config file.
+
+When the container is running, the memory utilization is around **30MB**.
+
+Use the stable version
+----------------------
+
+To fetch the latest stable release of Kanboard use the tag **stable**:
+
+```bash
+docker pull kanboard/kanboard
+docker run -d --name kanboard -p 80:80 -t kanboard/kanboard:stable
+```
+
+Use the development version (automated build)
+---------------------------------------------
+
+Every new commit on the repository trigger a new build on the [Docker Hub](https://registry.hub.docker.com/u/kanboard/kanboard/).
+
+```bash
+docker pull kanboard/kanboard
+docker run -d --name kanboard -p 80:80 -t kanboard/kanboard:latest
+```
+
+The tag **latest** is the **development version** of Kanboard, use at your own risk.
+
+Build your own Docker image
+---------------------------
+
+There is a `Dockerfile` in the Kanboard repository to build your own image.
+Clone the Kanboard repository and run the following command:
+
+```bash
+docker build -t youruser/kanboard:master .
+```
+
+or
+
+```bash
+make docker-image
+```
+
+To run your container in background on the port 80:
+
+```bash
+docker run -d --name kanboard -p 80:80 -t youruser/kanboard:master
+```
+
+Volumes
+-------
+
+You can attach 2 volumes to your container:
+
+- Data folder: `/var/www/app/data`
+- Plugins folder: `/var/www/app/plugins`
+
+Use the flag `-v` to mount a volume on the host machine like described in [official Docker documentation](https://docs.docker.com/engine/userguide/containers/dockervolumes/).
+
+Upgrade your container
+----------------------
+
+- Pull the new image
+- Remove the old container
+- Restart a new container with the same volumes
+

+
+The list of environment variables is available on [this page](env.markdown).
+
