On this page the various installation options are explained for several major operating systems. Users prioritizing ease of installation should choose to use a package manager or prebuilt bundle. Users prioritizing customization should build from source. It is important to run the latest version of Geth because each release includes bugfixes and improvement over the previous versions. The stable releases are recommended for most users because they have been fully tested. A list of stable releases can be found [here][geth-releases].
