+The SDK is not available for Linux at the moment. The best way to get started on Linux is to build Emscripten manually. See the "Installing from Source" section below. This ensures that you will get the most up-to-date configuration.

 * For help on Ubuntu, you can follow the [Getting Started on Ubuntu 12.10](https://github.com/kripken/emscripten/wiki/Getting-Started-on-Ubuntu-12.10) guide for instructions on how to obtain the prerequisites and build Clang manually using CMake.
 * For help on Debian, see this [guide by EarthServer](https://earthserver.com/Setting_up_emscripten_development_environment_on_Linux).
-* Debian Jessie includes a [emscripten package](https://packages.debian.org/jessie/emscripten).
 * rhelmer has provided a Vagrant VM for Emscripten, see [emscripten-vagrant](https://github.com/rhelmer/emscripten-vagrant).
 * Dirk Krause created an [Amazon EC2 image](https://groups.google.com/forum/?fromgroups=#!topic/emscripten-discuss/H8kG0kP1eDE) for Emscripten.
 
+Note that some distributions provide Emscripten in their package repositories. Please make note of the version number they are offering, since these will most certainly be very out of date!

 ### Installing from Source
 
 Instead of using the SDK, you can grab the code and dependencies yourself. This is the preferred path on Linux, where the Emscripten SDK is currently not available.
