 ## Compiling
-If you're a Windows user, you're in luck! If you head over to the [not-just-ready website](https://LibreSprite.github.io), you can find an installer for Windows. Currently we don’t have binaries available for Linux or Mac (more binaries incoming!), this means you will have to roll up your sleeves and compile LibreSprite if you want to try it out. Don't worry, it isn't as hard as you might think! Remember, we’re there to help you out at [#LibreSprite](https://webchat.freenode.net/#LibreSprite) if you get stuck.
