 # Usage
-Besides `rclone` this container also features `inotify`.
+`Rclone` is defined generically through the container environment.
+To find the name of the environment variable, first, take the long option name,
+strip the leading --, change - to _ make upper case and prepend RCLONE_.
+All available endpoints are described in the [official rclone documentation](https://rclone.org/commands/rclone_move/)
+of each command.
 ### Run `rclone` (default entrypoint)
 ```bash
 $ docker run --rm -it travelping/rclone:latest --help
 ```
 
+### Run `rclone` (sftp)
+This configuration provides a simple functionality test by enhancing the default entrypoint (`usr/bin/rclone`).
+Running a touch command on the remote path of a sftp server can be done entirely through environment.
+```bash
+docker run --rm -it -e RCLONE_CONFIG_SFTP_TYPE=sftp \
+-e RCLONE_CONFIG_SFTP_HOST=host.com \
+-e RCLONE_CONFIG_SFTP_USER=name \
+-e RCLONE_CONFIG_SFTP_PORT=23 \
+-e RCLONE_CONFIG_SFTP_PASS=mSZyspHocI375S3V7OupBbljCpqSnhD6 travelping/rclone:v1.0 touch sftp:path
+```
+
 ### Run shell
 ```bash
 $ docker run --rm -it --entrypoint=/bin/sh travelping/rclone:latest
 ```

-## Debugging
+## Inotify
+Besides `rclone` this container also features `inotify`. Watchpatterns can be used to make sure only finished files
+are being transfered.
 All inotify-events can be neatly logged using this command:
 ```
 inotifywait -mr --timefmt '%H:%M' --format '%T %w %e %f' /data/"
 ```
 
-## Script
-
+## Inotify-Script
 Wating for the `close_write` event, this command only pushes "finished" data to the destination.
