+INSTRUCTIONS FOR BUILDING XPWN
+------------------------------
+
+These are very basic instructions on how to build xpwn related projects, they
+are tailored to Debian based systems. They are not meant to be a substitute
+for experience in programming in GNU/Linux environments, but it should be a
+good starting point.
+
+1. Install a basic build environment (compilers, etc.):
+
+	sudo apt-get install build-essential
+
+2. Install some prerequisites libraries required by xpwn:
+
+	sudo apt-get install libcrypt-dev libz-dev libbz2-dev3 libusb-dev
+
+3. Install cmake. It is recommended you download and build it from the
+official cmake website, since versions >= 2.6.0 are recommended.
+
+	wget http://www.cmake.org/files/v2.6/cmake-2.6.2.tar.gz
+	tar zxvf cmake-2.6.2.tar.gz
+	cd cmake-2.6.2
+	./configure
+	make
+	sudo make install
+
+Now you are ready to build xpwn. It is highly recommended that you build
+out-of-source (that is, the build products are not placed into the same
+folders as the sources). This is much neater and cleaning up is as simple as
+deleting the build products folder.
+
+Assuming xpwn sources are in ~/xpwn:
+
+4. Create a build folder
+
+	cd ~
+	mkdir build
+	cd build
+
+5. Create Makefiles
+
+	cmake ~/xpwn
+
+6. Build
+
+	make
+
+7. Package
+
+	make package
+
+BUILDING USEFUL LIBRARIES
+-------------------------
+
+These command-lines can be substituted in for step 6. The products are in the
+subfolders (make package will not include them).
+
+xpwn library (for IPSW generation)
+
+	make libXPwn.a
+
+Windows pwnmetheus library (for QuickPwn)
+
+	make libpwnmetheus.dll
+
+HELPFUL MAKEFILE GENERATION COMMAND-LINES
+-----------------------------------------
+
+These command-lines can be substituted in for step 5.
+
+Add debugging symbols:
+
+	cmake ~/xpwn -DCMAKE_C_FLAGS=-g
+
+Try to only use static libraries:
+
+	cmake ~/xpwn -DBUILD_STATIC=YES
+
+
+CROSS-COMPILING
+---------------
+
+This is a complex and advanced topic, but it is possible with the appropriate
+CMake toolchain files and properly configured build environment. I have
+crossbuilt Windows, OS X, Linux x86, Linux x64, and iPhone binaries from one
+Ubuntu machine. The source trees are properly configured for this task.
+
+MORE HELP
+---------
+
+Consult the CMake documentation and wiki and look in the CMakeLists.txt files
+for hints on how things are supposed to work.
