 # ESP32-Mesh-OTA
 
-## Work in progress  
-<img src="https://patenschaft.bienenweide.org/img/loading.gif" alt="code_example_output" width="50"/>
-
-## Todo for first release
-
-### Refactoring
-- architecture
-- full error handling through all functions
-- export as a component library
-
-### Features
-- root node: Download new Firmware from HTTPS server instead using newest ota partition
-- add example main app
