+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
+
+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).

- A desktop platform with the [.NET Core SDK 2.1](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 Community Edition](https://www.visualstudio.com/) (Windows), [Visual Studio Code](https://code.visualstudio.com/) (with the C# plugin installed) or [Jetbrains Rider](https://www.jetbrains.com/rider/) (commercial).
+## Requirements

-# Building and running
+- A desktop platform with the [.NET Core 3.1 SDK](https://dotnet.microsoft.com/download) or higher installed.
+- When running on Linux, please have a system-wide FFmpeg installation available to support video decoding.
+- When running on Windows 7 or 8.1, **[additional prerequisites](https://docs.microsoft.com/en-us/dotnet/core/install/dependencies?tabs=netcore31&pivots=os-windows)** may be required to correctly run .NET Core applications if your operating system is not up-to-date with the latest service packs.
+- When developing with mobile, [Xamarin](https://docs.microsoft.com/en-us/xamarin/) is required, which is shipped together with Visual Studio or [Visual Studio for Mac](https://visualstudio.microsoft.com/vs/mac/).
+- When working with the codebase, we recommend using an IDE with intelligent code completion and syntax highlighting, such as [Visual Studio 2019+](https://visualstudio.microsoft.com/vs/), [JetBrains Rider](https://www.jetbrains.com/rider/) or [Visual Studio Code](https://code.visualstudio.com/).

-If you are not interested in developing the game, please head over to the [releases](https://github.com/ppy/osu/releases) to download a precompiled build with automatic updating enabled (download and run the install executable for your platform).
+## Running osu!

-Clone the repository including submodules
+### Releases

-`git clone --recurse-submodules https://github.com/ppy/osu`
+If you are not interested in developing the game, you can still consume our [binary releases](https://github.com/ppy/osu/releases).

-Build and run
+**Latest build:**

- Using Visual Studio 2017, Rider or Visual Studio Code (configurations are included)
- From command line using `dotnet run --project osu.Desktop`. When building for non-development purposes, add `-c Release` to gain higher performance.
- To run with code analysis, instead use `powershell ./build.ps1` or `build.sh`. This is currently only supported under windows due to [resharper cli shortcomings](https://youtrack.jetbrains.com/issue/RSRP-410004). Alternative, you can install resharper or use rider to get inline support in your IDE of choice.
+| [Windows (x64)](https://github.com/ppy/osu/releases/latest/download/install.exe)  | [macOS 10.12+](https://github.com/ppy/osu/releases/latest/download/osu.app.zip) | [iOS(iOS 10+)](https://osu.ppy.sh/home/testflight) | [Android (5+)](https://github.com/ppy/osu/releases/latest/download/sh.ppy.osulazer.apk)
+| ------------- | ------------- | ------------- | ------------- |

-Note: If you run from command line under linux, you will need to prefix the output folder to your `LD_LIBRARY_PATH`. See `.vscode/launch.json` for an example
+- **Linux** users are recommended to self-compile until we have official deployment in place.

-If you run into issues building you may need to restore nuget packages (commonly via `dotnet restore`). Visual Studio Code users must run `Restore` task from debug tab before attempt to build.
+If your platform is not listed above, there is still a chance you can manually build it by following the instructions below.

-# Contributing
+### Downloading the source code

-We welcome all contributions, but keep in mind that we already have a lot of the UI designed. If you wish to work on something with the intention on having it included in the official distribution, please open an issue for discussion and we will give you what you need from a design perspective to proceed. If you want to make *changes* to the design, we recommend you open an issue with your intentions before spending too much time, to ensure no effort is wasted.
+Clone the repository:

-Please make sure you are familiar with the [development and testing](https://github.com/ppy/osu-framework/wiki/Development-and-Testing) procedure we have set up. New component development, and where possible, bug fixing and debugging existing components **should always be done under VisualTests**.
+```shell
+git clone https://github.com/ppy/osu
+cd osu
+```

-Contributions can be made via pull requests to this repository. We hope to credit and reward larger contributions via a [bounty system](https://www.bountysource.com/teams/ppy). If you're unsure of what you can help with, check out the [list of open issues](https://github.com/ppy/osu/issues).
+To update the source code to the latest commit, run the following command inside the `osu` directory:

-Note that while we already have certain standards in place, nothing is set in stone. If you have an issue with the way code is structured; with any libraries we are using; with any processes involved with contributing, *please* bring it up. I welcome all feedback so we can make contributing to this project as pain-free as possible.
+```shell
+git pull
+```

-# Licence
+### Building

-The osu! client code and framework are licensed under the [MIT licence](https://opensource.org/licenses/MIT). Please see [the licence file](LICENCE) for more information. [tl;dr](https://tldrlegal.com/license/mit-license) you can do whatever you want as long as you include the original copyright and license notice in any copy of the software/source.
+Build configurations for the recommended IDEs (listed above) are included. You should use the provided Build/Run functionality of your IDE to get things going. When testing or building new components, it's highly encouraged you use the `VisualTests` project/configuration. More information on this is provided [below](#contributing).
+
+- Visual Studio / Rider users should load the project via one of the platform-specific `.slnf` files, rather than the main `.sln.` This will allow access to template run configurations.
+- Visual Studio Code users must run the `Restore` task before any build attempt.
+
+You can also build and run *osu!* from the command-line with a single command:
+
+```shell
+dotnet run --project osu.Desktop
+```
+
+If you are not interested in debugging *osu!*, you can add `-c Release` to gain performance. In this case, you must replace `Debug` with `Release` in any commands mentioned in this document.
+
+If the build fails, try to restore NuGet packages with `dotnet restore`.
+
+_Due to a historical feature gap between .NET Core and Xamarin, running `dotnet` CLI from the root directory will not work for most commands. This can be resolved by specifying a target `.csproj` or the helper project at `build/Desktop.proj`. Configurations have been provided to work around this issue for all supported IDEs mentioned above._
+
+### Testing with resource/framework modifications
+
+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
+
+Before committing your code, please run a code formatter. This can be achieved by running `dotnet format` in the command line, or using the `Format code` command in your IDE.
+
+We have adopted some cross-platform, compiler integrated analyzers. They can provide warnings when you are editing, building inside IDE or from command line, as-if they are provided by the compiler itself.
+
+JetBrains ReSharper InspectCode is also used for wider rule sets. You can run it from PowerShell with `.\InspectCode.ps1`, which is [only supported on Windows](https://youtrack.jetbrains.com/issue/RSRP-410004). Alternatively, you can install ReSharper or use Rider to get inline support in your IDE of choice.
