RPM packages are published with each release, and can be downloaded from GitHub.
After cloning the repository, ensure that cargo (the rust build tool) and make are available. The project can then be built and installed on a local machine by running. You may also require other build dependencies, like fuse3-devel depending on the components of your system. A typical list of dependencies can be found in the rpm spec file.
make install # both spfs and spk
make install-spfs # only spfs
Currently, only spfs is supported on windows and is still considered experimental. File systems can be mounted and viewed, but not modified. See above on building from source - windows builds will require WinFSP to be installed rather than fuse libraries.
