 # VRipper!
 
-This is my spin for a cross platform gallery ripper app for [vipergirls](https://vipergirls.to) website.
-The purpose of this project is to build a robust and clean application to conveniently download photo galleries using modern web technologies, Java + Spring boot for the back end and angular + electron for the front end.
+This is my spin for a cross-platform gallery ripper for [vipergirls.to](https://vipergirls.to).
 
 ## How to build
-You need a recent version of maven 3.6.1+.
 
-The application support 2 build modes:
- - Desktop app: Self contained app, built with electron includes Java runtimes.
- - Server app: Depends on Java runtimes, you need a web browser to access the app UI.
+You need JDK 17 and a recent version of maven 3.6.1+
 
-Most people will be interested only on the desktop app, however if you have a nas or a server, the server app is there for you.
+To build run the following:
 
-To build the server app:
+    mvn clean install
 
-    mvn clean install -DskipTests
+Build artifact is located under
 
-To build the desktop app:
+    vripper-project\vripper-gui\target\vripper-gui-{{version}}.jar
 
-    mvn clean install -Pelectron -DskipTests
+Copy the artifact into any other folder and run:
 
-Maven will automatically handle front end compilation. However, for development, you will need to install a recent
-version of nodejs on your system.
-
-If you feel generous and want to support me, you can donate some coins, and I would be very grateful 🙏
