Just seem feedback. Not sure if this is the right section, but as there is no feedback section, thought was probably the best :P.
For Linux, whilst it may seem super simple to other people to run a .sh, it is not for everyone. As it is not as common a file type as say flatpak or a .deb or etc.
Something I would recommend for the guide (https://www.notion.so/Backup-locally-to-any-cloud-provider-7dacad9e95b44c5db681033fc264fb59) is after 4 put in an extra two lines of text from 1. and the first line of 2. from here (https://www.cyberciti.biz/faq/run-execute-sh-shell-script/) to explain how to run the file. Then explain that the app is now available to be opened from Navigation. Such as 6 being changed to ‘Open the app from Navigation’ (Start Menu).
Great program, thanks.
