+How to create a monkey build environment:
+
+Windows:
+1. Install python 2.7
+	https://www.python.org/download/releases/2.7
+2. install pywin32-219.win32-py2.7.exe
+	http://sourceforge.net/projects/pywin32/files/pywin32/Build%20219/
+3. install VCForPython27.msi
+	http://www.microsoft.com/en-us/download/details.aspx?id=44266
+4. Download & Run get-pip.py
+	https://bootstrap.pypa.io/get-pip.py
+5. Run:
+	setx path "%path%;C:\Python27\;C:\Python27\Scripts"
+	python -m pip install enum34
+	python -m pip install impacket
+	python -m pip install PyCrypto
+	python -m pip install pyasn1
+	python -m pip install cffi
+	python -m pip install twisted
+	python -m pip install rdpy
+	python -m pip install requests
+	python -m pip install odict
+	python -m pip install paramiko
+	python -m pip install psutil	
+	python -m pip install PyInstaller
+	type C:\Python27\Lib\site-packages\zope\__init__.py
+6. Put source code in C:\Code\monkey\chaos_monkey
+7. Download and extract UPX binary to C:\Code\monkey\chaos_monkey\bin\upx.exe:
+	http://upx.sourceforge.net/download/upx391w.zip
+8. Run C:\Code\monkey\chaos_monkey\build_windows.bat to build, output is in dist\monkey.exe
+
+Linux (Tested on Ubuntu 12.04):
+1. Run:
+	sudo apt-get update
+	apt-get install python-pip python-dev libffi-dev upx
+	sudo pip install enum34
+	sudo pip install impacket
+	sudo pip install PyCrypto --upgrade
+	sudo pip install pyasn1
+	sudo pip install cffi
+	sudo pip install zope.interface --upgrade
+	sudo pip install twisted
+	sudo pip install rdpy
+	sudo pip install requests --upgrade
+	sudo pip install odict
+	sudo pip install paramiko
+	sudo pip install psutil
+	sudo pip install https://github.com/pyinstaller/pyinstaller/releases/download/3.0.dev2/PyInstaller-3.0.dev2.tar.gz
+	sudo apt-get install winbind
+2. Put source code in /home/user/Code/monkey/chaos_monkey
+3. To build, run in terminal:
+	cd /home/user/Code/monkey/chaos_monkey
+	chmod +x build_linux.sh
+	./build_linux.sh
+   output is in dist/monkey
+
+How to connect build environment to c&c:
+- will auto compile the source code stored in the c&c and update the c&c binaries accordingly
+Linux (Tested on Ubuntu 12.04):
+	1. Setup c&c according to readme in monkey_island folder
+	2. Install cifs:
+		sudo apt-get install cifs-utils
+	3. Run:
+		mkdir /home/user/Code	
+		sudo mkdir /mnt/sources
+		sudo mkdir /mnt/binaries
+	4. Save username and password for c&c smb:
+		echo username=<username> > /home/user/.smbcreds
+		echo password=<password> >> /home/user/.smbcreds
+		(Change <username> and <password> according to c&c)
+	5. Edit fstab:
+		run: sudo nano /etc/fstab
+		add rows:
+			//monkeycc/sources /mnt/sources cifs iocharset=utf-8,credentials=/home/user/.smbcreds,uid=1000 0 0
+			//monkeycc/binaries /mnt/binaries cifs iocharset=utf-8,credentials=/home/user/.smbcreds,uid=1000 0 0
+	6. Remount:
+		sudo mount -a
+	7. Check if sources exist in /mnt/sources
+		If not, edit hosts file - add a line in /etc/hosts with c&c ip and hostname and remount.
+	8. put build_from_cc.sh in /home/user and run with name of output binary (as appeared on c&c) as parameter,
+		for example: build_from_cc.sh monkey-linux-32
+		use Ctrl+C to manualy check compilation and Ctrl+\ to exit script.
+
+Windows:
+	1. Setup c&c according to readme in monkey_island folder
+	2. Setup net use to c&c server:
+		net use Z:\ \\monkeycc\sources /persistent:yes
+		net use X:\ \\monkeycc\binaries /persistent:yes
+	3. mkdir C:\Code
+	4. Extract build_from_cc.bat to c:\code and run with name of output binary (as appeared on c&c) as parameter,
+		for example: build_from_cc.bat monkey-windows-64.exe
