+SASS Asset Pipeline
+==========================
+The `sass-dart-asset-pipeline` is a plugin that provides SASS / SCSS support for the asset-pipeline static asset management plugin using the [dart-sass](https://sass-lang.com/dart-sass) native JS compiler.
+
+The plugin uses [Javet](https://www.caoccao.com/Javet/) (based on Google's V8 runtime) to allow for execution of the dart-sass JS compiler directly from Java.
+
+For more information on how to use asset-pipeline, visit [here](http://www.github.com/bertramdev/asset-pipeline).
+
+Integration
+===========
+Javet requires native libraries for integration. The first time you execute the pipeline, the appropriate native library will be downloaded for your platform. The supported
+platforms are:
+
+* Linux - x86_64
+* Windows - x86_64
+* MacOS - x86_64, arm64
+
+The platform JAR is downloaded by default from Maven Central to the Java system temp directory. You can
+override this behavior by setting the following options:
+
+* javetBaseUrl = "https://repo1.maven.org/maven2/com/caoccao/javet" (default)
+* javetLibraryHome = System.getProperty('java.io.tmpdir') (default)
+
+If the native library already exists at `javetLibraryHome` it will not be downloaded again.
+
+The full platform URL is constructed from the `javetBaseUrl`. 
+
+For example, on Mac OS, it would look like this:
+
+`"${javetBaseUrl}/javet-macos/1.0.6/javet-macos-1.0.6.jar"`
+
+Configuration
+-------------
+Configuration is passed through to the dart-sass compiler:
+
+https://sass-lang.com/documentation/js-api/interfaces/LegacyStringOptions
+
+Common options are:
+
+* sass.outputStyle = "expanded" | "compressed" (default: "expanded")
+* sass.indentType = "space" | "tab" (default "space")
+* sass.indentWidth = 0..10 (default: 2)
+* sass.quietDeps = boolean (default: false) - Don't report deprecation warnings for imported files
+
+For example:
+```
+assets {
+    configOptions = [
+        javetBaseUrl: 'https://myrepo.mycompany.com/repository/com/caoccao/javet'
+        sass: [
+            quietDeps: true, 
+            outputStyle: 'compressed'
+        ]
+    ]
+}
+```
+
+Usage
+-----
+Simply create `scss` or `sass` files in your assets folder.
+
+Things to be done
+-----------------
+* Find a way to generate proper source maps with full paths
