= Introduction = Note 1: If you are reading this on any site but http://www.opensimulator.org, you might not be actually downloading OpenSimulator.org software. Please check your browser URL before proceeding any further.

Note 2: Depending on what you want to do with OpenSimulator, setting it up may require a fair amount of technical knowledge. After downloading OpenSim, please consult the several instruction manuals on this Wiki and elsewhere. Please be aware that the learning curve for operating OpenSim is steep.

Note 3: Many Linux distros (including Ubuntu) ship with only the "mono-runtime" package installed, however you need to install "mono-complete" for some OpenSimulator features such as LSL script commands. You must also use at least Mono V2.4.3 (Ubuntu 10.04 ships with mono 2.4.4 which works fine).

As OpenSim is still at an alpha code maturity stage, there is absolutely no guarantee that functionality works or is stable.

= Binary Packages =

Current release
Binary packages of the latest OpenSimulator release are provided in .zip or .tar.gz form - these are identical apart from the compression format. Once you've unzipped/untarred these you'll be able to run OpenSimulator 'out of the box' in standalone mode - no code compilation required.

The current release is  (released on ) and can be downloaded at:


 * http://dist.opensimulator.org/opensim--bin.tar.gz or
 * http://dist.opensimulator.org/opensim--bin.zip

After unpacking please read the Release Notes. Further instructions may be found in README.txt after you untar/unzip the archives.

= Installers =

The OpenSimulator project does not currently provide installers for the latest releases - you're better off downloading the binary packages and just unzipping them - this is equivalent to an installation. There are some Debian/Ubuntu packages but these are not maintained.

UnofficialDebPackages
 * '''0.6.6 (and other releases/revs) unofficial Debian and Ubuntu Linux .deb packages

= Other Distributions =

Other projects are free to repackage OpenSimulator and add their own modules or configuration. Current known distributions are
