@SebTota What @Wieber has forgotten to mention is that the config.js.sample file is the default configuration that is included with the mirror software. The mirror software itself is looking for config.js. So the step that is missing is to copy the sample to the end file name. Once you have it copied over, this will become the file that you use to change your mirror’s behavior.
You copy the file with this command: cp ~/MagicMirror/config/config.js.sample ~/MagicMirror/config/config.js
You can then edit the config.js command as you have already discovered: nano ~/MagicMirror/config/config.js Nano is the editor, config.js is the file you are editing.
