 ### Building libretro cores
 You should at least build one libretro implementation so RetroArch can do stuff.
 There is a [super-project](https://github.com/libretro/libretro-super) that is designed to easily build every libretro port out there. To build every core:
-
-    git clone git://github.com/libretro/libretro-super.git
-    cd libretro-super
-    sh libretro-fetch.sh
-    sh libretro-build.sh
-    sh libretro-install.sh <path>
+```bash
+git clone git://github.com/libretro/libretro-super.git
+cd libretro-super
+sh libretro-fetch.sh
+sh libretro-build.sh
+sh libretro-install.sh <path>
+```
     
 ### Building RetroArch
-Once dependencies are installed, you can pull and install from Git:
-
-    git clone git://github.com/Themaister/RetroArch.git
-    cd RetroArch
-    ./configure # Script will autodetect features. Refer to --help if you want to override anything, such as --prefix.
-    make
-    sudo make install
+```bash
+cd retroarch
+./configure # Script will autodetect features. Refer to --help if you want to override anything, such as --prefix.
+make
+sudo make install
+```
 
 ### Building RetroArch-Phoenix (GUI launcher)
 If you want a GUI launcher as well, you can build it too:
-
-    git clone git://github.com/Themaister/RetroArch-Phoenix.git
-    cd RetroArch-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
+```bash
+git clone git://github.com/Themaister/RetroArch-Phoenix.git
+cd RetroArch-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! :)
