## Smilium (programming language)

- [Smilium 2.1 language reference](https://smileytech.mk/smilium/reference.md): the canonical spec for generating and understanding Smilium code — syntax rules, all types, methods, builtins, events, with examples. Read this before writing any .smy code.
- [Smilium docs & online playground](https://smileytech.mk/smilium): human documentation with runnable examples and an in-browser interpreter.

## SmileyOS

- [SmileyOS](https://smileytech.mk/smileyos): the operating system — try it in the browser.
- [SmileyOS App SDK](https://smileytech.mk/smileyos-sdk): building GUI apps for SmileyOS.
