 ### In a nutshell:
 * Very simple and intuitive API (see [demos](./source//demos/)), with TypeScript definitions included.
 * Bundler friendly, designed with tree-shakeability in mind.
-    * *Not 100% tree-shakeable right now, but close. And working on it.*
 * Opinionated:
-    * Only targets **x64** platforms (*ARM-64 may be added later, no warranty though*).
+    * Only targets **64-bit** platforms (*Intel/AMD for now, ARM may be added later, no warranty though*).
     * Only exposes **Unicode** functions and data structures (those whose name ends in `W` in the Win32 API).
 * Very easy to extend with additional functions, data structures and constants. I will add some myself time permitting; any help would be *mucho* appreciated.

 1. Install the lib in your project: `npm install libwin32`

+1. Import the functions and types you need. You may either import from `libwin32` or from `libwin32/<dllname>` (without the `.dll` extension) if you know which dll a function beglons to. Currently, only two dlls are available: `kernel32` and `user32`.
+1. (optional) Import some complementary constants. They greatly simplify calls to the Win32 API.
+    * All constants are available via the `libwin32/consts` import.
+    * Logically grouped constants are exported as `enum`s, where the prefix is the name of the enum. For instance, `WM_DESTROY` and `WM_KEYDOWN` are exported as `WM_.DESTROY` and `WM_.KEYDOWN`, respectively.
 1. Call the functions as instructed by the [Win32 API documentation](https://learn.microsoft.com/en-us/windows/win32/api/). All functions, constants and types are named accordingly.
-    * Constants like `WM_DESTROY` are exported as `enum`s, where the prefix is the name of the enum. For instance, `WM_DESTROY` and `WM_KEYDOWN` are exported as `WM.DESTROY` and `WM.KEYDOWN`, respectively.
