 ## Building
 
-It is a Gradle Kotlin/JVM project and `./gradlew build` would work, but
-depending on the distribution you may have to edit [build.gradle](alsakt-javacpp/build.gradle#L33) and/or [Alsa.java](alsakt-javacpp/src/main/java/alsakt_presets/Alsa.java) configuration.
+Since alsakt 0.3.0, it bundles `libasound.so` on x86_64 Linux (maybe doable for other architectures, but needs native build setup). Before trying to build the Kotlin/JVM library, we have to build `libasound.so` first:
+
+```
+./build-native.sh
+```
+
+Then the resulting shared library will be packaged within the .jar by JavaCPP builder.
+
+It is a Gradle Kotlin/JVM project and `./gradlew build` takes care of the Kotlin/JVM part.
