Install
The latest version of the Gren compiler is 0.4.5 (changelog).
The fastest way to install the compiler is through NPM:
> npm install -g gren-lang
It's also possible to use asdf with the asdf-gren plugin.
If none of these work for you, then you can always build your own compiler from source.
Once you have the compiler installed on your system, it is time to learn the language.
