• Clone https://github.com/tbwcjw/nxducominer.git.
• Copy config.sample.txt to config.txt and fill in the fields^*.
• make (all) - build the application and generate a release.
  make build - build the application.
  make release - builds and generate a release.
  make clean - removes build/build data. does not remove releases
• Use NXLink to send application.nro and fptd to send the config.txt, ensuring it is in the same directory as application.nro.

Roadmap

Short term	Mid term	Long term
Automatically select node. Better error handling. Reconnect to node if connection lost. Handle consoleExit() without error. Prevent switch from auto-sleeping in app.	Web dashboard, like the ESP32 miner Multithreading.	Pretty GUI.
