+## Primitives - /nt/primitives
+All expressions in the `/nt/primitives` directory should have no dependencies on NixTypes
+because **`/nt/primitives` is the dependency of NixTypes**! However for consistency in
+the development process `/nt/primitives` is structured using the Mix Module subsystem
+(`/nt/primitives/mix`).
+
+*"But Emile..."* I hear you say! **How can primitives be a Mix module if Mix depends on primitives??**
+Welp I'm sure I could have done some cool exploit of lazy evaluation in recursion,
+*but I was alas lazy...* So the solution is **they can't... ;-;** But they can be pretty close!
+
+Instead we have `/nt/primitives/bootstrap`! Which provides a **miniature dependency-free standard library.**
+`import ./nt/primitives/bootstrap/default.nix` is passed as to `import ./nt/primitives/mix` which is
+then passed to `import ./nt`.
+
+Most importantly, `/nt/primitives/bootstrap/default.nix` contains the function `bootstrap:: Path | List | Attrs | Function -> Attrs`:
+```nix
+# et voilà!
+let
+  this = bootstrap {inherit this bootstrap;} [
+    {
+      std = ./std/bootstrap.nix;
+      types = ./types/bootstrap.nix;
+      parse = ./parse/bootstrap.nix;
+    }
+  ];
+in
+  this;
+```
+**\~\~!!KABOOM !!\~\~**
+
+Now **our primitives have a primitive module system!**
+
+The init process looks like this:
+```nix
+# REF: flake.nix
+{
+  outputs = _: let
+    # Step 1: Bootstrap and blast off (*zooommmmm whoooosshhhhh pppppeeeeeeewww*)
+    bootstrap = import ./nt/primitives/bootstrap;
+    # Step 2: Lie to Mix about its real identity (it's not ready for the truth...)
+    mix = import ./nt/primitives/mix {this = bootstrap;};
+  in
+    # Step 3: Actually import NixTypes
+    import ./nt {inherit mix;};
+    # Step 4: Like and subscripe!!1!11!!!!!
+}
+```
+
+
+## A note on /nt/primitives/bootstrap
+**None of these functions/types/etc are exported for users of NixTypes!** So they should
+remain as simple and minimal as possible to avoid extra work maintaining.
+Instead, **most of these will be reimplemented post-bootstrap to be NixType compatible**.

-The `/nt/primitives` directory should have no dependencies on NixTypes *(with one exception explained below)*.
-Thus the **NixTypes system must be constructed from a dependency-free standard library.**
-
-This includes dependency on `this` (provided by the `nt.mix` module system)!
-`/nt/primitives` is structured as a `nt.mix` module, and hence `/nt/primitives/mix`
-must also depend on `/nt/primitives/std`. My point is, **`/nt/primitives/std`
-cannot use mix at all!**
-
-### Internal Use Only
-**None of these functions are exported for users of NixTypes!** So they should
-remain as simple and minimal as possible to avoid extra work maintaining.
-Instead, **all of these functions will be reimplemented** post-bootstrap
