Typical hardware and software requirements are:
- **24/7 availability:** A dedicated system connected by Ethernet and running continuously.
- **Energy and space efficient:** A device capable of performing the task at hand without being exaggerated
- **Extendibility:** Your system should be capable of running additional software like an MQTT broker or a persistence and graphing software.
- **Peripherals:** Depending on your home automation hardware, you will need additional peripheral devices such as a WiFi interface or a special USB radio module.

Please download and install the **Java 11** version of the JVM.
openHAB 3 will use Java 11 and you *can* go for it with 2.X, too, but be aware that although developers are working hard to make this work, there might be problems with the oldest parts of openHAB such as some of the v1 bindings due to non-backward compatible changes in Java 11.
Note that openHAB 3 will run under Java 11, and you *can* use it with openHAB 2.X as well.

1. openHAB is available as a platform independent archive file or through a package repository:
- **Manual setup:** Download and extract a platform independent zip archive: [macOS](macos.html), [Windows](windows.html), [Linux](linux.html#manual-installation)
- **Package setup:** Install through a package repository, including automatic updates.
This option is only available for Debian or Ubuntu derivatives and the recommended choice: [Linux (apt/deb)](linux.html#package-repository-installation)
- **Package setup:** Install from a package repository, using a package manager such as apt or yum.
This option is only available for certain Linux distributions such as Debian or Ubuntu derivatives, but allows you to take advantage of automatic updates and is the recommended choice: [Linux (apt/deb)](linux.html#package-repository-installation)
2. Stable release or cutting edge:
- **Stable:** Use the latest official release ([hosted on Bintray](https://bintray.com/openhab/mvn/openhab-distro)).
