 # Viper Ripper!
 
-This is my spin for a gallery ripper app for [vipergirls](https://vipergirls.to) website.
+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.
 
 ## How to build
 You need a recent version of maven 3.6.1+.
 
 The application support 2 build modes:
- - Desktop app (*Partially cross platform): Self contained app, built with electron, depends on Java runtimes.
- - Server app (Fully cross platform): Depends on Java runtimes, you need a web browser to access the app UI.
+ - 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.
 
 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 the server app:
 
-    mvn clean install
+    mvn clean install -DskipTests
 To build the desktop app:
 
-    mvn clean install -Pelectron
+    mvn clean install -Pelectron -DskipTests
 
 Maven will automatically handle front end compilation. However, for development, you will need to install a recent version of nodejs on your system.
 
-*Partially cross platform:
-Technically cross platform, but the Desktop app relies on electron builder to make appropriate binaries for each platform. mac binaries can only be generated on a mac, and i don't own one. So i can only provide binaries for windows and linux.
-The Server app however depends only on Java, so it will work just fine on a mac, you only need a browser to access it.
