+This plugin packages native libraries produced by JniNative in a way that they can be transparently loaded with JniLoad. It uses the notion of a native "platform", defined as the architecture-kernel values returned by `uname -sm`, or using the `os.name` and `os.arch` properties if the `uname` command is not available. A native binary of a given platform is assumed to be executable on any machines of the same platform.
 
 ## Canonical Use
 
@@ -325,7 +325,7 @@ Real-world use-cases of sbt-jni include:
 
 - projects using `JniLoad` must use Scala versions 2.11, 2.12, 2.13 or 3.2
   - projects using `JniLoad` with Scala 3 should use it with the `sbtJniCoreScope := Compile` SBT key set
-- only POSIX platforms are supported (actually, any platform that has the `uname` command available)
+- only POSIX platforms are supported
 
 The goal of sbt-jni is to be the least intrusive possible. No transitive dependencies are added to projects using any plugin (some dependencies are added to the `provided` configuration, however these do not affect any downstream projects).
