-# topiku
-topiku is a simple [LISP](https://en.wikipedia.org/wiki/Lisp_(programming_language)) inspired language with [toki pona](https://tokipona.org/) keywords
-
-## Building
-To build `topiku` interpreter you need a [Zig](https://ziglang.org/) compiler (works with `master`) and [`editline`](https://github.com/troglobit/editline) installed.
-```sh
-> git clone https://git.ablecorp.us:443/der-teufel-programming/topiku.git
-> cd topiku
-> zig build
-```
-The executable is then found as `zig-out/bin/topiku`
-It is also possible to build and run using `zig build run` command.
