 Rhythm is just a *click* away. The future of [osu!](https://osu.ppy.sh) and the beginning of an open era! Commonly known by the codename "osu!lazer". Pew pew.
 
-# Status
+## Status
 
 This project is still heavily under development, but is in a state where users are encouraged to try it out and keep it installed alongside the stable osu! client. It will continue to evolve over the coming months and hopefully bring some new unique features to the table.
 
 We are accepting bug reports (please report with as much detail as possible). Feature requests are welcome as long as you read and understand the contribution guidelines listed below.
 
-# Requirements
+Detailed changelogs are published on the [official osu! site](https://osu.ppy.sh/home/changelog).
+
+## Requirements
 
 - A desktop platform with the [.NET Core SDK 2.2](https://www.microsoft.com/net/learn/get-started) or higher installed.
 - When working with the codebase, we recommend using an IDE with intellisense and syntax highlighting, such as [Visual Studio 2017+](https://visualstudio.microsoft.com/vs/), [Jetbrains Rider](https://www.jetbrains.com/rider/) or [Visual Studio Code](https://code.visualstudio.com/).
 - Note that there are **[additional requirements for Windows 7 and Windows 8.1](https://docs.microsoft.com/en-us/dotnet/core/windows-prerequisites?tabs=netcore2x)** which you may need to manually install if your operating system is not up-to-date.

-- Windows (x64) users should download and run `install.exe`.
-- macOS users (10.12 "Sierra" and higher) should download and run `osu.app.zip`.

+- **iOS** users can join the [TestFlight beta program](https://t.co/PasE1zrHhw) (note that due to high demand this is regularly full).
+- **Android** users can self-compile, and expect a public beta soon.

 Sometimes it may be necessary to cross-test changes in [osu-resources](https://github.com/ppy/osu-resources) or [osu-framework](https://github.com/ppy/osu-framework). This can be achieved by running some commands as documented on the [osu-resources](https://github.com/ppy/osu-resources/wiki/Testing-local-resources-checkout-with-other-projects) and [osu-framework](https://github.com/ppy/osu-framework/wiki/Testing-local-framework-checkout-with-other-projects) wiki pages.

 Code analysis can be run with `powershell ./build.ps1` or `build.sh`.

Alternatively, you can install resharper or use rider to get inline support in your IDE of choice.
