Samuell, please note that we are shipping Luna together with Atom.io app. Look at `.luna/config/luna-studio/1.0/atom/packages/luna-studio/lib`. The main Luna Studio lib is around 35mb on my computer. There is also a compiler and some small plugins. Everything else are npm's node_modules and Atoms ecosystem. We will distribute Luna Studio without Atom in the future, then it will be super-lightweight.

Does it make sense to you?
