-_This project is currently in it's early prototype stage. You can see other versions in various branches or tagged as prototype-X._
+You can find the [latest nightly build here](https://dl.dropboxusercontent.com/u/46669050/Tortuga.rar).
 
-Tortuga is a 2D multiplayer role playing game set in a large archipelago occupied by warring pirate clans. The emphasis of this game is on multiplayer cooperation, competition, and server customization. The game runs on highly customizable server software that can support up to 150 simultaneous players or more. The player characters are tied to the server where they are created and are susceptible to permadeath: deletion of a character upon death.
+Tortuga is an open source 2D multiplayer role playing game featuring permadeath (deletion of a character upon death). The emphasis of this game is on multiplayer cooperation, competition, and customization. The game runs on customizable server software that can support up to 150 simultaneous players or more.
 
-## Dependencies
+This game is inspired by classic 2D RPGs, as well as more modern sandbox MMOs. This project is currently independently created and funded, with the goal of creating a game that will engage user's imagination and inspire a large modding community.
 
-* [SDL](http://www.libsdl.org/) - Simple DirectMedia Layer API
-* [SDL_net](http://www.libsdl.org/projects/SDL_net/) - SDL's networking extension
+## External Dependencies
 
-## Instructions
+* [SDL 1.6](http://www.libsdl.org/) - Simple DirectMedia Layer API
+* [SDL_net 1.2](http://www.libsdl.org/projects/SDL_net/) - SDL's networking extension
+* [lua 5.2](http://www.lua.org/) - The lua programming language
+* [SQLite3](http://www.sqlite.org/) - A lightweight SQL database engine
 
-* This project uses C++11, which is available via GNU (or MinGW) 4.7, or Visual Studio 2012. Personally, I'm using MinGW 4.7.2.
-* I'm trying to keep this as IDE agnostic as possible, so if you use an IDE, please add it's files to .gitignore.
-* You can read more details on the Tortuga wiki [here](https://github.com/Ratstail91/Tortuga/wiki).
