+
+## Interface description / API usage
+
+As Mongoose-OS is used as platform for this software, all Mongoose-OS supported RPC-Mechanisms are supported, which are:
+
+- USB: Easiest is to start browser based UI ("> mos ui") or  by following command line:<br />
+*mos --port /dev/ttyUSB0 call TP.Print '{"text": "Text to be printed"}'*
+- MQTT: *mos --port mqtt://my.mqtt.server:1883/esp32_6732ac call TP.Print '{"text": "Text to be printed"}'*
+- WS (WebSocket): *mos --port ws://192.168.0.206/rpc call TP.Print '{"text": "Text to be printed"}'*
+- RESTful HTTP call: *curl -d '{"text": "Text to be printed"}' 192.168.0.206/rpc/TP.Print*
+
+## Printed Text Formatting
+
+The text to be printed is formatted using markdown notation (not fully supported, just "like markdown"). You may use following formattings:
+
+- lines starting with # are used as headlines, printed with double width and height
+- inline formattings used:
+  - "\*" character is used to mark begin and end of emphasized strings, which are printed bold. Example: *Text to be \*emphasized**
+  - "\_" underline character is used to mark begin and end of underlined text. Example: *Text to be \_underlined_*
+  - Characters can be escaped using the "\\" character. This might be changed by configuration (config parameter tp.escapeCharacter, see Config-RPC service)
+
+## Configuration
+
+You may use the Mongoose-OS configuration service to change the behaviour and interface of this module. E.g. use *"> mos --port /dev/USB0 config-get"* to get the current configuration and *"> mos --port /dev/USB0 config-set key=value"* to set a configuration value.
+
+The only specific configuration is everything that is defined under the "tp" key. MQTT, Wifi, debugging and other settings may be changed and are available from Mongoose-OS anyway. A shortcut to set the Wifi settings is: *"> mos --port /dev/USB0 wifi WIFI_NAME WIFI_PASSWORD"*.
+
+## OTA
+
+The firmware may be updated using OTA services offered by Mongoose-OS (see https://mongoose-os.com/docs/book/ota.html).
