Extract the file with “Extract here” in the file manager.
Optionally, move and/or rename the newly created folder to where you want margin to reside. A common choice is ~/opt/margin
Go into the margin folder and run the file called “margin”. Before the first run, the icon will be a default icon and not the margin logo shown in the screenshot.
Optionally, if you want to copy the .desktop file used to run margin to a different place, e. g. your desktop, or ~/.local/share/applications/
to be seen by your desktop environment, you'll have to change the last line to read something like
Exec=/home/username/opt/margin/run-margin.sh
Adapt for the location you actually put margin in.
