## Third Party Viewer

As a third party maintained fork of the [Second Life][] viewer, which includes Apple Silicon native builds, Megapahit viewer is indexed in the [Third Party Viewer Directory][tpv].

## Download

Most people use a pre-built viewer release to access Second Life. macOS, GNU/Linux and FreeBSD builds are
[published on the official website][download]. More experimental viewers, such as release candidates and
project viewers, would be detailed on the same page, [in-world group][] notices, or [Discord][] server.

## Build Instructions

```
$ git clone git://megapahit.org/viewer.git
$ cd viewer
$ mkdir build-`uname -s|tr '[:upper:]' '[:lower:]'`-`uname -m`
$ cd build-`uname -s|tr '[:upper:]' '[:lower:]'`-`uname -m`
```
