 Todo; currently under development. Will make it possible to assign actions/files/folders to RFID-tags and configure some things.
 
 ### FTP
-In order to avoid disassembling the Tonuino all the time, it's possible to transfer music onto the sd-card using FTP. Please make sure to set the max. number of parallel connections to ONE in your FTP-client. My recommendation is [Filezilla](https://filezilla-project.org/). But don't expect fast transfer, it's only around 145 kB/s and decreases dramatically, if music is played in parallel. Better stop playback then doing a FTP-transfer.

Default-user and password are set via ftpUser and ftpPassword.
 
 ### Energy saving
-As already described in the modify-section, there are different sleepmodes available. Additionaly, uC will be put into deepsleep after 10 minutes (maxInactivityTime) unless Tonuino doesn't play music, has a FTP-client connected and any input via buttons.
+As already described in the modify-section, there are different sleepmodes available. Additionaly uC will be put into deepsleep after 10 minutes of inactivity (configurable my maxInactivityTime) unless Tonuino doesn't play music, has a FTP-client connected and any input via buttons. Every button-interaction resets the counter to the initial value.
 
 ### MQTT
-Everything, that can be controlled via RFID-tags and buttons can also be done via MQTT. All manual interactions (buttons, RFID-tags) are also sent to MQTT, so everything is always in-sync (unless Wifi/MQTT-connection is broken). In my home-setup I'm using [openHAB](https://www.openhab.org/) to encapsulate MQTT into a nice GUI, that's accessible via APP + web. ToDo: Publish sample-configuration for openHAB.

 ### Supported file/stream-types
 Please refer [ESP32-audioI2S](https://github.com/schreibfaul1/ESP32-audioI2S), as this is the lib I integrated for music-decoding.
