+### Dependencies:
+
+You'll need to download and install the following to build yuzu:
+
+* [SDL2](https://www.libsdl.org/download-2.0.php)
+  - Deb: `apt-get install sdl2` or `apt-get install libsdl2-2.0-0` or `apt-get install libsdl2-dev`
+  - Arch: `pacman -S sdl2`
+  - Fedora: `dnf install SDL2-devel`
+* [Qt](http://qt-project.org/downloads)
+  - Deb: `apt-get install qtbase5-dev libqt5opengl5-dev`
+  - Arch: `pacman -S qt5`
+  - Fedora: `dnf install qt5-qtbase qt5-qtbase-devel`
+* GCC v5+ (for C++14 support)
+  - Deb: `apt-get install build-essential`
+  - Arch: `pacman -S base-devel`
+  - Fedora: `dnf install gcc-c++`
+* [CMake](http://www.cmake.org/) 3.6+
+  - Deb: `apt-get install cmake`
+  - Arch: `pacman -S cmake`
+  - Fedora: `dnf install cmake`
+* [Clang](https://github.com/llvm-mirror/clang) 3.8 (optional build alternative)
+  - Deb: `apt-get install clang libc++-dev` (in some distros, clang-3.8).
+  - Arch: `pacman -S clang`, `libc++` is in the AUR. Use pacaur or yaourt to install it.
+* Curl
+  - Deb: `apt-get install libcurl4-openssl-dev`
+  - Arch `pacman -S libcurl-compat`
+
+### Cloning yuzu in Git:
+
+```
+git clone --recursive https://github.com/yuzu-emu/yuzu
+cd yuzu
+```
+
+The `--recursive` option automatically clones the required Git submodules too.
+
+### Building yuzu in Debug Mode (Slow):
+
+**Using gcc:**
+
+```
+mkdir build && cd build
+cmake ../ -DUSE_SYSTEM_CURL=1
+make
+sudo make install
+```
+Optionally, you can use "cmake -i .." to adjust various options (e.g. disable the Qt GUI).
+
+**Using clang:**
+
+Note: It is important you use libc++ vs. , otherwise your build will likely fail. libc++ is not 100% complete on GNU/Linux, but works well for this build. The libstdc++ std::string is a different data structure than the libc++ std::string. See: [LLVLM.org](https://llvm.org/svn/llvm-project/www-releases/trunk/3.8.0/projects/libcxx/docs/UsingLibcxx.html). If libc++ is not used, some warnings are treated as errors. Using clang is only really recommended for users not using GCC >= 5. Also see [Clang Comparison](http://clang.llvm.org/comparison.html).
+
+```
+mkdir build && cd build
+cmake  -DCMAKE_CXX_COMPILER=clang++-3.8 \
+	-DCMAKE_C_COMPILER=clang-3.8 \
+	-DCMAKE_CXX_FLAGS="-O2 -g -stdlib=libc++" \
+        -DUSE_SYSTEM_CURL=1  ..
+make
+sudo make install (currently doesn't work, needs to be fixed)
+```
+Debian/Ubuntu: Owing to bug [#808086](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=808086) the build might
+fail. To have it build, add the following after line 1938 of `/usr/include/c++/v1/string`. (see discussion on
+[StackOverflow](http://stackoverflow.com/questions/37096062/get-a-basic-c-program-to-compile-using-clang-on-ubuntu-16)
+for more details.)
+
+```
+#if _LIBCPP_STD_VER <= 14
+    _NOEXCEPT_(is_nothrow_copy_constructible<allocator_type>::value)
+#else
+    _NOEXCEPT
+#endif
+```
+
+Additionally, on Ubuntu,
+do `sudo apt-get install libc++abi-dev && sudo ln -s /usr/include/libcxxabi/__cxxabi_config.h /usr/include/c++/v1/__cxxabi_config.h`
+
+
+### Building yuzu in Release Mode (Optimized):
+
+```
+mkdir build && cd build
+cmake .. -DCMAKE_BUILD_TYPE=Release -DUSE_SYSTEM_CURL=1
+make
+sudo make install (currently doesn't work, needs to be fixed)
+```
+
+### Building with debug symbols:
+
+```
+cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo -DUSE_SYSTEM_CURL=1
+make
+```
+
+### Running without installing:
+
+After building, the binaries `yuzu` and `yuzu-qt` (depending on your build options) will end up in `build/src/<binary_name>/`. 
+
+```
+# SDL
+cd build/src/yuzu/
+./yuzu
+
+# Qt
+cd build/src/yuzu_qt/
+./yuzu-qt
+```
+
+### Debugging:
+
+```
+cd data
+gdb ../build/src/yuzu_qt/yuzu-qt
+(gdb) run
+<crash>
+(gdb) bt
+```
