 ================================
 
 Kanboard can run easily with [Docker](https://www.docker.com).
-There is a `Dockerfile` in the repository to build your own container.
+
+The image size is approximately **50MB** and contains:
+
+- [Alpine Linux](http://alpinelinux.org/)
+- The [process manager S6](http://skarnet.org/software/s6/)
+- Nginx
+- PHP-FPM
+
+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 **20MB**.

+Volumes
----------------------------
+-------
 
-By default Kanboard will store attachments and the Sqlite database in the directory data. Run this command to use a custom volume path:
+You can attach 2 volumes to your container:
 
-```bash
+- Data folder: `/var/www/kanboard/data`
-docker run -d --name kanboard -v /your/local/data/folder:/var/www/html/data -p 80:80 -t kanboard/kanboard:master
+- Plugins folder: `/var/www/kanboard/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/).
+
+Config files
+------------
+
+- The container already include a custom config file located at `/var/www/kanboard/config.php`.
+- You can store your own config file on the data volume: `/var/www/kanboard/data/config.php`.
