Setup MCP was done mostly by the people who update the wiki, I just changed it a bit. Some credit goes to BuildCraft's README.md, which I based this README off of.
1. Download and install the Java JDK [here](http://www.oracle.com/technetwork/java/javase/downloads/index.html). Click the one that says `Java Platform (JDK) #u#`, and follow instructions.
* Go to `Control Panel\System and Security\System`, and click on `Advanced System Settings` on the left-hand side.
* Click on `Environment Variables`.
* Under `System Variables`, click `New`.
* For `Variable Name`, input `JAVA_HOME`.
* For `Variable Value`, input something similar to `;C:\Program Files (x86)\Java\jdk1.7.0_09` exactly as shown to the end.(or wherever your Java JDK installation is), and click `Ok`.
* Scroll down to a variable named `Path`, and double-click on it.
* Append `;C:\Program Files (x86)\Java\jdk1.7.0_09\bin` (or wherever your Java JDK installation is \bin), and click `Ok`.
* You should see Github flash and `pahimar/Equivalent-Exchange-3` appear. (The local repository defaults to `C:\Users\(username)\Documents\GitHub\Equivalent-Exchange-3`, you can change it if you want but then you have to find it again on Github).
4. Create an empty directory for EE3 development. This directory is refernced as `mcdev` from now on. It can be where you cloned EE3, but it'll be a little messy.
1. Download the latest version of MCP from [here] (http://mcp.ocean-labs.de/index.php/MCP_Releases), e.g. mcp723.zip. Install MCP dependencies as listed on the website if neccessary.
4. From your `.minecraft` directory (on Windows, defaults to `%appdata%\.minecraft`), copy the `bin` and the `resources` (not sure if necessary) directory to the `jars` directory inside `mcp`. (Forge might do this for you, not confirmed.)
6. Download the latest forge **source** for Minecraft 1.4.5 and unzip it into `mcp` so that `mcp\forge\install.sh` exists. You need at least Forge 6.4.0, best way is to get it from [here] (http://files.minecraftforge.net/).
7. Execute `install.sh` (Linux and Mac) or `install.cmd` (Windows), both found in `mcdev\mcp\forge`. On Linux you might have to `chmod +x``install.sh` before you can execute it. On some system configurations you need to execute `install.sh` from within the `forge` directory whereas on others it doesn't matter. Just check the output for error messages to find out what you need to do.
7. Execute `ant release`. This will generally take around 5-15 minutes, depending on your computer. If you've done everything right, `BUILD SUCCESSFUL` is displayed after it finishes.
* If you see `BUILD FAILED`, check the error output (it should be right around `BUILD FAILED`), fix everything, and try again.
8. Go to `mcdev\source\Equivalent-Exchange-3\Releases\1.4.5\pre2` (This might be different according to what you put in build.properties).
* You should see a .jar named `ee3-universal-pre2.jar` (Again, might be different).
