 While SceneBuilder does not support adding custom themes, it is possible to overwrite looked-up CSS paths to make the <ins>existing buttons load custom CSS files</ins>.
 
-In order to use AtlantaFX in SceneBuilder you need to:
+**(not yet released)**
 
-* Run `mvn package -pl styles` to generate theme CSS files with the correct path names.
-* Copy `styles/target/AtlantaFX-${version}-scenebuilder.zip` to the SceneBuilder `$APPDIR` (e.g. `%HOMEPATH%/Local/SceneBuilder/app/` on Windows) or another directory of your choice.
-* Open `SceneBuilder.cfg` in the SceneBuilder app directory and add the zip file to the beginning of the `app.classpath` variable, e.g.:
+![Project structure](assets/images/scene-builder-integration.png)
+
+### Manual
+
+* Run `mvn package -pl styles` to generate theme package. You can also download it on the [Releases](https://github.com/mkpaz/atlantafx/releases) page.
+* Copy `styles/target/AtlantaFX-${version}-scenebuilder.zip` to the SceneBuilder `app/` directory (e.g. `%HOMEPATH%/Local/SceneBuilder/app/` on Windows) or another directory depending on where you installed SceneBuilder application on your PC.
+* Open `SceneBuilder.cfg` in the SceneBuilder app directory and add the ZIP file to the beginning of the `app.classpath` variable, e.g.:
 
     ```text
-    app.classpath=$APPDIR\AtlantaFX-${version}-scenebuilder.zip;$APPDIR\scenebuilder-18.0.0-all.jar
+    # beware about file separator (slash or backslash) depending on your OS
+    app.classpath=$APPDIR\AtlantaFX-${version}-scenebuilder.zip:$APPDIR\scenebuilder-18.0.0-all.jar
     ```
 
 * Restart SceneBuilder.
 
 Then you can select AtlantaFX themes in the menu `Preview -> Themes -> Caspian Embedded (FX2)`. The themes are mapped as follows:
 
-| SceneBuilder                | Modifier                    | AtlantaFX Theme |
+| SceneBuilder                | Caspian High Contrast (FX2) | AtlantaFX Theme |
 |-----------------------------|-----------------------------|-----------------|
-| Caspian Embedded (FX2)      | None                        | Primer Light    |
-| Caspian Embedded (FX2)      | Caspian High Contrast (FX2) | Primer Dark     |
-| Caspian Embedded QVGA (FX2) | None                        | Nord Light      |
-| Caspian Embedded QVGA (FX2) | Caspian High Contrast (FX2) | Nord Dark       |
+| Caspian Embedded (FX2)      | disabled                    | Primer Light    |
+| Caspian Embedded (FX2)      | enabled                     | Primer Dark     |
