**[Second Life][] is a free 3D virtual world where users can create, connect and chat with others from around the world.** This repository contains the source code for the official client. ## Open Source Second Life provides a huge variety of tools for expression, content creation, socialization and play. Its vibrancy is only possible because of input and contributions from its residents. The client codebase has been open source since 2007 and is available under the LGPL license. The [Open Source Portal][] contains additional information about Linden Lab's open source history and projects. ## Download Most people use a pre-built viewer release to access Second Life.
