-You can just build a container image from this repository.
+You can use the docker image [crycode/http-server-upload](https://hub.docker.com/r/crycode/http-server-upload) from the Docker Hub.
+
+Simple usage example:
 
 ```sh
-docker build -t http-server-upload .
+docker run --rm -it -p 8080:8080 crycode/http-server-upload
 ```
 
-Then run it without argument for default
+You may also overwrite default options using environment variables  (see below for available variables) and use volumes or bind mounts for upload storage:
 
 ```sh
-docker run --rm -ti http-server-upload
+docker run --rm -it -p 8080:8080 -e TOKEN=foo -e ENABLE_FOLDER_CREATION=1 -v $(pwd):/upload crycode/http-server-upload
 ```
 
-Or you can override default values with environment variables (see blow for available variables).
-`UPLOAD_DIR` and `UPLOAD_TMP_DIR` are set to `/upload`. You may find it useful to mount a volume in this directory to keep uploaded files. Keep in mind that this volume must be writeable by the `node` user. More complete example.
+Or you build a container image youself from this repository:
 
 ```sh
-docker run --rm -ti -e PORT=9090 -e UPLOAD_DIR=/data -v myvolume:/data -p 80:9090 http-server-upload
+docker build -t http-server-upload .
 ```
