### Compiling Equivalent Exchange 3
IMPORTANT: This is not guaranteed to work as it has not been tested extensively (Linux and Windows tested).
***
#### Prerequisites  (Tested for Windows ONLY!)
1. **WARNING:  Make sure you know EXACTLY what you're doing!  It's not any of our faults if your OS crashes, becomes corrupted, etc.**
2. Download and install the Java JDK [here] (http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html).  Scroll down, accept the `Oracle Binary Code License Agreement for Java SE`, and download the one pertaining to your OS (necessary for MCP).
	* 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_21` 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_21\bin` (or your Java JDK installation directory\bin), and click `Ok`.
3. Download Apache Ant [here] (http://ant.apache.org).
	* Unzip the files anywhere you want, eg `C:\Program Files (x86)\Ant`.
  * Again, go to `Environment Variables` just like you did for the Java JDK.
  * Under `System Variables`, click `New`.
  * For `Variable Name`, input `ANT_HOME`.
  * For `Variable Value`, input `C:\Ant\apache-ant-1.9.0` (or your Ant directory\apache-ant-1.9.0).
  * Scroll down to `Path`, and double-click on it.
  * Append `;C:\Ant\apache-ant-1.9.0\bin` exactly as shown to the end (or your Ant directory\apache-ant-1.9.0\bin).
4. Download and install Github [here] (http://windows.github.com/) (Windows) or [here] (http://mac.github.com/) (Mac OS X 10.7+).  For Linux, you could download it as a .zip/tarball and unzip it.
	* Create an account.
  * Scroll to the top of this page, login at the top-right, and then click `Clone to Windows/Mac` near the top-left of the page.
  * You should see Github flash and `pahimar/Equivalent-Exchange-3` appear.  (The local repository on Windows 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).
5. 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.


#### Setup MCP (Tested on Linux and Windows)
1. Download the latest version of MCP from [here] (http://mcp.ocean-labs.de/index.php/MCP_Releases), e.g. mcp751.zip. Install MCP dependencies as listed on the website if neccessary.
2. Inside `mcdev`, create a directory named `mcp` and unzip the MCP .zip file into it.
	* To verify, check if a file named `CHANGELOG` exists inside `mcp`.
3. Download the latest forge **source** for Minecraft 1.5.2 and unzip it into `mcp`.  You need at least Forge 7.7.1.500 (Forge 7.8.0.684 if using 1.5.2), best way is to get it from [here] (http://files.minecraftforge.net/).
	* To verify, check if a applications named `install.sh` and `install.cmd` exists. 
4. 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.

#### Setup EE3 (Some tested for Linux, tested fully for Windows)
1. Inside `mcdev`, create a directory named `source`.
2. Move/clone `Equivalent-Exchange-3` into `source`.
3. Right now, you should have a directory that looks something like:

***

	mcdev
	\-mcp
		\-complicated mcp stuff (should have CHANGELOG).
		\-forge
		\-jars
	\-source
		\-Equivalent-Exchange-3
			\-EE3's files (should have build.xml).
***

4. Inside `Equivalent-Exchange-3`, create a new file called `build.properties`.
	* Open it up with any text editor, and type into it the following (fully customizable except for `dir.development`):
 		* `dir.development=../../`
		* `dir.release=Releases`
		* `release.minecraft.version=1.5.2`
		* `release.mod.version=pre2`
5. Open up your OS's command line (Command Prompt in Windows, Terminal in Linux and Mac).
6. Navigate to `mcdev\source\Equivalent-Exchange-3` by executing `cd mcdev's location\source\Equivalent-Exchange-3`.
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\1.5.2\pre2`.
	*  You should see a .jar named `ee3-universal-pre2.jar`.
9. Copy the jar into your Minecraft mods folder, and play Minecraft!

#### Updating Your Repo (For Windows/Mac)
1. Check to see if pahimar updated EE3 since you last compiled.  If he did, follow these instructions.
2. Open Github.
3. Double-click on pahimar/Equivalent-Exchange-3.
4. At the top, there is a button named `Sync`/`Sync Branch` (or `Refreshing...` if it's still checking).
5. Click `Sync`, and wait for it to finish.
6. Re-compile (or move it to `mcdev\source` then re-compile, depending on what you did.)
