Repository with assets used by ThingsBoard UI help engine.
You may run a simple web server to host the files (assuming you are in the project folder):
sudo npm install --global http-server
http-server . -p 8081 --cors
Now the help assets are available using url: http:https://localhost:8081.
Launch ThingsBoard with configuration parameter:
UI_HELP_BASE_URL=http:https://localhost:8081
