-In order to build Hentai@Home, you need the following:
+In order to build Hentai@Home, you just need OpenJDK 8 or newer.
 
-- The sqlite-jdbc-3.7.2 SQLiteJDBC library, placed in this directory (obtainable from http://g.e-hentai.org/hentaiathome.php or http://www.xerial.org/trac/Xerial/wiki/SQLiteJDBC)
+In a Windows build environment, run make.bat and makejar.bat in order. On Linux, do make then make jar (or make all).
 
-- The Java(TM) SE JDK, version 6 or greater
+This will produce two .jar files, HentaiAtHome.jar and HentaiAtHomeGUI.jar, in the current directory. Move these .jar files to a location of your choice - this is where H@H will store all its files by default.
 
-In a Windows build environment, run make.bat and makejar.bat in order. On Linux, do make then make jar (or make all). This will produce two .jar files, HentaiAtHome.jar and HentaiAtHomeGUI.jar, in the current directory. These two files along with sqlite-jdbc-3.7.2 constitutes the entire program.
+In a GUI environment you can usually just double-click HentaiAtHomeGUI.jar to start it. Alternatively, from a command-line, use java -jar HentaiAtHome.jar for the CLI version or java -jar HentaiAtHomeGUI.jar for the GUI version.
 
-Move the three .jar files to a location of your choice (this is where H@H will store all its files), and run java -jar HentaiAtHome.jar for the CLI version or java -jar HentaiAtHomeGUI.jar for the GUI version.
