 ## What the hell is this?
 
-Lints is an experimental operating system kernel written almost entirely in TypeScript. This is not some in-browser system emulator or WebAssembly hack; Lints actually runs on real hardware (or a hardware emulator like QEMU) by leveraging a JavaScript engine with a small C kernel (just some basic memory management needed by the JS engine) and JS-to-C bindings for purposes like writting data to pointers, etc.
