I wonder, if you are new to USDe, and you download the wallet, From windows for example, you download the zip, unarchive it and simply click the QT client?
in my %appdata% in usde I don't have a usde.conf file , I also run the wallet directly from archive and it's working.
Do you still need to create that usde.conf file and copy those lines of code?
You will need the usde.conf file only if you are solo mining. If you are pool mining, you do not have to worry about usde.conf file.
