-# Space Invaders
-
-## About
-This is a simple clone I wrote in a weekend using `odin-lang` and the available `raylib` bindings.
-
-# Software used
-* `Aseprite` for pixel art
-* `neovim` and the `ols` LSP
-* `make`
-
-# Building & running
-This should be buildable through the makefile on any platform (Windows, OSX & Linux) as long as you have the Odin compiler on hand.
-If the makefile is causing you trouble the project can be directly ran with (which creates a binary file as well):
-
-```bash
-odin run .
-```
-or compiled to a binary with a custom output directory & speed optimizations (although they are not needed at all):
-```bash
-odin build . -out:space_invaders.exe -o:speed
-```
