-## Developing or debugging
+## Developing a custom ruleset
+
+osu! is designed to have extensible modular gameplay modes, called "rulesets". Building one of these allows a developer to harness the power of osu! for their own game style. To get started working on a ruleset, we have some templates available [here](https://github.com/ppy/osu-templates).
+
+You can see some examples of custom rulesets by visiting the [custom ruleset directory](https://github.com/ppy/osu/issues/5852).
+
+## Developing osu!
 
 Please make sure you have the following prerequisites:
 
-- A desktop platform with the [.NET Core 3.1 SDK](https://dotnet.microsoft.com/download) or higher installed.
+- A desktop platform with the [.NET 5.0 SDK](https://dotnet.microsoft.com/download) or higher installed.
 - 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/).
 - When running on Linux, please have a system-wide FFmpeg installation available to support video decoding.

 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.
