+
+## Nix as first-class citizen instead of native config
+
+- Nix can export JSON and other object serialization formats
+
+- Still allows native config, so that Neovim, for example, which uses Turing-complete
+  config language, to make full use of its native LSP.
+
+## Design pattern emerges from unstructured code
+
+### Modules
+
+- Main thing for the first big refactor of codebase
+
+- nixpkgs and home-manager has their own interface for modules 
+
+- The main benefit is to provide (runtime) type-safety on options, along with
+documentations and defaults
+
+## Nitpicky details
+
+### `nativeBuildInputs` vs `buildInputs`
+
+- `nativeBuildInputs` is available **before** `buildInputs`.
+
+- `nativeBuildInputs` is supposed to be built by a deployment machine (not target)
+
+- `buildInputs` gives you access during runtime
+
+- `nativeBulidInputs` gives you access to packages during build time
+
+- `mkShell` doesn't care about `packages`, `nativeBuildInputs`, `buildInputs`
