System Requirements

To get YaCy running, the only thing you need is a somehow recent computer (everything that used to be up-to-date in this millennium should be all right) and an operating system that supports Java. Apart from this, you should allow for 25GB of memory on your HD for collected data on websites and the index itself. Your computer can never have enough memory (RAM), but 256MB are quite enough to start with. Less is also acceptable, but it will make work a bit slow.

YaCy has been written in the Java programming language, which means that it is available for a great number of computer systems, as Java is available for almost all systems in use. An outstanding feature of Java programs is the fact that they can be run on different systems without any modification.

Java can be downloaded and used for free. If there is no Java environment on your system yet, you must install it before installing YaCy. Java is available from the Sun website. The recent version is Java 6. The minimum Java version you need for YaCy is Java 5 (also known as 1.5) - which might change in the future.

Because of this - and the fact that the newer Java version is more powerful than the old one - you should chose Java 6 right from the start. If the only thing you want to do is just run Java programs you can make do with the JRE (Java Runtime Environment). If you want to develop Java programs or even help making YaCy better, you will need the JDK Java Development Kit.
