This adds a flake.nix file that makes it possible to quickly create a development environment. You can download Nix here, for use on your Linux or macOS system: https://nixos.org/download.html After you have installed Nix, you can enter the development environment as follows: nix develop This drops you into a bash shell, where you can install TinyGo simply using the following command: go install That's all! Assuming you've set up your $PATH correctly, you can now use the tinygo command as usual: tinygo version You can also do many other things from this environment. Building and flashing should work as you're used to: it's not a VM or container so there are no access restrictions.pull/3949/head
