First of all, Nottelo app has to be installed on your device (so far we support desktop OS only). App can be downloaded right here. To install Nottelo, all you have to do is to run downloaded installer for your macOS / windows / linux computer.
When the app is installed and started, you should see blue dot icon in your tray bar. Clicking the icon should open app.notello.com address where you will find the registration which is the very last step of setting up Nottelo. When you are registered and logged in to your account, you are good to go.
You should see demo content in left panel represented by PERSONAL and WORK places with projects. Feel free to look around to see what can be done with Nottelo and when you're done, you might want to delete these places and create your own.
