 IGraph/M can also be installed manually in the same way as any _Mathematica_ application distributed as a paclet.

 IGraph/M requires Mathematica 10.0.2 or later.  Binaries are included for Windows 64-bit, OS X 10.9 or later, Linux x86_64 and Raspbian (Linux ARM on Raspberry Pi).  For other operating systems the package must be compiled from source (see [Development.md](Development.md) for guidance).
