Download and install Sonarr
Sonarr provides ready-made installers for every platform. Go to the official download page and grab the right one for your OS. On Windows you get a normal .exe installer. On Linux/Raspberry Pi you run a one-line install script from their wiki. The installer sets Sonarr up as a background service so it starts automatically with your computer.
Linux script asks for your password and you see 'permission denied'
Make sure you typed 'sudo bash' at the end of the command. sudo gives the script the admin rights it needs.
