+# C# wrapper
+
+## Requirements
+
+You will need to install the [.NET SDK](https://dotnet.microsoft.com/download), which includes the `dotnet` tool. The
+wrapper targets .NET Standard 2.0, so which means that at least .NET Core 2.0 is required (.NET 5+ is also fine). For
+the tests, .NET 5 or newer is required.
+
+## Build & test
+
 First build the shared Go library. Next:
 
 Build `EduVpnCommon`:
+
 ```shell
 make
 ```
 
 Build as nupkg, including eduvpn_verify library:
+
 ```shell
 make pack
 ```

+The wrapper targets .NET Standard 2.0, which means that it can be referenced by projects using either .NET Framework
+4.6.1+, .NET Core 2.0+, or .NET 5+.

+Currently, directly referencing the project may not work (with `System.BadImageFormatException`) if you have multiple

 methods [here](https://stackoverflow.com/q/43400069) or [here](https://stackoverflow.com/q/10240029), it automatically
 copies the correct library.
 
 Test:

 ```shell
 make test
