 There are prebuilt binaries available in the [releases section](https://github.com/laamaa/m8c/releases/) for Windows and recent versions of MacOS.
 
-## Linux / MacOS (building from source)
+### Linux
 
-These instructions are tested with Raspberry Pi 3 B+ and Raspberry Pi OS with desktop (March 4 2021 release), but should apply for other Debian/Ubuntu flavors as well. The begining on the build process on OSX is slightly different at the start, and then the same once packages are installed.
+There are packages available for Fedora Linux and NixOS, or you can build the program from source.
 
-The instructions assume that you already have a working Linux desktop installation with an internet connection.
+#### Fedora
+``` sh
+sudo dnf copr enable laamaa/m8c
+sudo dnf install m8c
+```
 
-Open Terminal and run the following commands:
+#### NixOS
+``` sh
+nix-env -iA m8c-stable -f https://github.com/laamaa/m8c/archive/refs/heads/main.tar.gz
