Single RPM file
To install a single, downloaded RPM file:
Open the Dolphin file manager => Navigate to the RPM file => Click on it and follow the instructions
Or use the command line if you wish:
Tarball
If the website doesn't have an RPM for openSUSE, it will most likely have a so-called "tarball". Tarballs
(*.tar.gz, *.tar.bz2) are simply compressed archives similar to *.zip and *.rar files. To uncompress a tarball:
Open the Dolphin file manager => Navigate to the tarball => Right click => Extract Archive
The tarball might contain binaries that just need to be ran, or it might contain source code which needs to be
compiled to run on your system - which can be complicated, and requires you to first install various
developer tools. There's no one standard way to install tarball content, but you should always be able to
find instructions in included files called INSTALL, README or similar - or on the website.
