 ## Installation
 
+Currently, we support only
+the [GNU](https://gcc.gnu.org/) toolchain for the native artifacts.
+For `GPU` kernels, we require a compatible
+[CUDA](https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html)
+installation. If you are on Windows, we recommend setting up
+everything on [WSL](https://docs.nvidia.com/cuda/wsl-user-guide/index.html).

 To install the library, you can simply publish to the local
 Maven repository:
 ```
 ./gradlew -q :kmath-noa:publishToMavenLocal
 ```
-This will fetch and build native artifacts as well.

+In your own application add the local dependency:
+```kotlin
+repositories {
+    mavenCentral()
+    mavenLocal()
+}
+
+dependencies {
+    implementation("space.kscience:kmath-noa:0.3.0-dev-14")
+}
+```
+To load the native library you will need to add to the VM options:
+```
