+How to make your own sources and use them
+1) Download and install intellij
+2) Make a folder called iTopZ-Java
+3) Download the sources like in image below
+![https://prnt.sc/w6zkpg](0.png)
+4) Open the folder with the extracted items
+![https://prnt.sc/w6zkpg](1.png)
+5) The files should look now like this
+![https://prnt.sc/w6zkpg](2.png)
+6) Select project and in top menu select Build and then Build artifacts
+![https://prnt.sc/w6zkpg](3.png)
+7) A new menu will open you can either build all or select the one you want
+![https://prnt.sc/w6zkpg](4.png)
+8) Finally, you can find the build jar inside "out" folder
+9) Copy it on your sources usually on lib or libs folder inside eclipse
+10) Right click on it -> add to class path
+11) Go in your GameServer.java and somewhere call it as VDSystemManager.getInstance();
+12) press ctrl+shift+o to import it and build your server
+
+Notes
+1) You can replace jars of any project with newer or older and try to apply the project on that jar
+2) The VDSystem isn't require any project source only a l2jserver.jar file
+3) A successful build look like this
+![https://prnt.sc/w6zkpg](5.png)
+4) Here you can see the installed modules
+![https://prnt.sc/w6zkpg](6.png)
+5) Here you can edit the l2jserver jar libraries
+![https://prnt.sc/w6zkpg](7.png)
+6) Here are the artifacts that consist the build function
+![https://prnt.sc/w6zkpg](8.png)
+7) Here you can see and verify the installed JDK versions or point out the already installed paths
+![https://prnt.sc/w6zkpg](9.png)
+8) You need to have installed and set on project the following JDK versions 1.7, 1.8, 11, 14, 15
+![https://prnt.sc/w6zkpg](10.png)
+9) Here are the vendors that you can download the JDK versions
+![https://prnt.sc/w6zkpg](11.png)
+That's it, you now can have your own build remove unnecessary projects.
