 Prerequisites
-- **Must**: .NET 6 SDK
-- **Should**: [NUKE](https://nuke.build) (build system). Install using `dotnet tool install Nuke.GlobalTool --global`
-- **Should**: Android, iOS, and MAUI .NET 6 workloads (use `dotnet workload install android ios maccatalyst maui` to install them)
-- **Should**: Android SDK version 30 with NDK tools installed. On Windows, for best results this should be installed into `C:\ProgramData\Android\android-sdk`.
-- **Could**: Java JDK (for gradle)
-- **Could**: Visual Studio 2022 Community version 17.0 or later
+- .NET 6 SDK and .NET 7 SDK
+- Android, iOS, and Mac Catalyst workloads (use `dotnet workload install android ios maccatalyst` to install them)
+    - On Linux, `ios` and `maccatalyst` should be omitted as they are not available
+- Android SDK version 30 with NDK tools installed
+    - On Windows, for best results this should be installed into `C:\ProgramData\Android\android-sdk`
+- Java 11 JDK
+- Visual Studio 2022 Community version 17.0 or later (optional)
 
 Instructions
 - Clone the repository (recursively)
 - Run build.sh, build.cmd, build.ps1, or `nuke compile`.
+    - On Linux, you may need to pass `--msbuild-properties AndroidSdkDirectory=/path/to/android/sdk`
 - Use the DLLs. To get nupkgs you can use with NuGet instead, use `nuke pack`.
 
 There are more advanced build actions you can do too, such as FullBuild, Pack, FullPack, among others which you can view by doing `nuke --plan`.
