+Compilation on Linux and BSD does not have many surprises, as its foundation is Unix-based.
+
+### Dependencies
+SDL
+libsnes
+pkg-config
+Working OpenGL headers (should be included by default, but you might need to install libgl/mesa development packages)
+
+### Optional dependencies
+libxml2 - For XML shaders and cheat support.<br/>
+freetype - TTF font rendering<br/>
+ffmpeg/libavcodec - FFmpeg recording (**Note**: You will need a very recent build of FFmpeg to compile, use latest Git checkout)<br/>
+nvidia-cg-toolkit - Cg shaders<br/>
+
+Some other libraries can be built support for as well, please refer to ./configure --help.
+
+### Building libsnes
+Here I assume you will use the bSNES emulation core. If you have GCC 4.5 or a more recent one, you can build from the vanilla sources which uses C++11 features.
+If you do not have a GCC 4.5 compiler handy, you can build from the C++98 port. This will allow you to build bSNES even on GCC 3.x compilers and Clang++.
+
+    git clone git://github.com/Themaister/libsnes.git
+    cd libsnes
+    make profile=performance # You can use compatibility or accuracy if desired.
+    sudo make install # Use prefix=/path/to/prefix as well to install to someplace else than /usr/local/lib as normal.
+    
+### Building SSNES
+Once dependencies are installed, you can pull and install from Git:
+
+    git clone git://github.com/Themaister/SSNES.git
+    cd SSNES
+    ./configure # Script will autodetect features. Refer to --help if you want to override anything, such as --prefix.
+    make
+    sudo make install
+
+### Building SSNES-Phoenix (GUI launcher)
+If you want a GUI launcher as well, you can build it too:
+
+    git clone git://github.com/Themaister/SSNES-Phoenix.git
+    cd SSNES-Phoenix
+    make # Will build for GTK2 by default. If you're a KDE user or prefer Qt, you can build for Qt with make -f Makefile.qt.
+    sudo make install
+
+Enjoy! :)
