 ## Purpose
 
 The goal of this project is to make the easiest, fastest, and most
 painless way of setting up a self-hosted Git service.
-Using Go, this can be done with an independent binary distribution across
-**all platforms** which Go supports, including Linux, macOS, and Windows
-on x86, amd64, ARM and PowerPC architectures.
-Want to try it before doing anything else?
-Do it [with the online demo](https://try.gitea.io/)!

+As Gitea is written in Go, it works across **all** the platforms and
