 First, you need to generate Makefiles for LLVM with CMake. You need to
 make a build directory and run CMake from it:
 
-::
+.. code-block:: console
 
-      mkdir your/build/directory
-      cd your/build/directory
-      cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=ON path/to/llvm/sources
+  $ mkdir your/build/directory
+  $ cd your/build/directory
+  $ cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=ON path/to/llvm/sources
 
 If you want to use clang instead of GCC, you can add
-``-DCMAKE_C_COMPILER=/path/to/clang   -DCMAKE_CXX_COMPILER=/path/to/clang++``.
-You can also use ccmake, which provides a curses interface to configure
+``-DCMAKE_C_COMPILER=/path/to/clang -DCMAKE_CXX_COMPILER=/path/to/clang++``.
+You can also use ``ccmake``, which provides a curses interface to configure
 CMake variables for lazy people.
 
 As a result, the new ``compile_commands.json`` file should appear in the
 current directory. You should link it to the LLVM source tree so that
 Clang Tooling is able to use it:
 
-::
+.. code-block:: console
 
-      ln -s $PWD/compile_commands.json path/to/llvm/source/
+  $ ln -s $PWD/compile_commands.json path/to/llvm/source/
 
 Now you are ready to build and test LLVM using make:
 
-::
+.. code-block:: console
 
-      make check-all
+  $ make check-all
 
 Using Clang Tools
 =================
 
-After you completed the previous steps, you are ready to run clang
-tools. If you have a recent clang installed, you should have
-``clang-check`` in $PATH. Try to run it on any .cpp file inside the LLVM
-source tree:

 (Experimental) Using Ninja Build System

 development, so you can get latest development sources and build it
 yourself:
 
-::
+.. code-block:: console
 
-      git clone git://cmake.org/cmake.git
-      cd cmake
-      ./bootstrap
-      make
-      sudo make install
+  $ git clone git://cmake.org/cmake.git
+  $ cd cmake
+  $ ./bootstrap
+  $ make
+  $ sudo make install
 
 Having the correct version of CMake, you can clone the Ninja git
 repository and build Ninja from sources:
 
-::
+.. code-block:: console
 
-      git clone git://github.com/martine/ninja.git
-      cd ninja/
-      ./bootstrap.py
+  $ git clone git://github.com/martine/ninja.git
+  $ cd ninja/
+  $ ./bootstrap.py
 
 This will result in a single binary ``ninja`` in the current directory.
 It doesn't require installation and can just be copied to any location
 inside ``$PATH``, say ``/usr/local/bin/``:
 
-::
+.. code-block:: console
 
-      sudo cp ninja /usr/local/bin/
-      sudo chmod a+rx /usr/local/bin/ninja
+  $ sudo cp ninja /usr/local/bin/
+  $ sudo chmod a+rx /usr/local/bin/ninja
 
 After doing all of this, you'll need to generate Ninja build files for
 LLVM with CMake. You need to make a build directory and run CMake from
 it:
 
-::
+.. code-block:: console
 
-      mkdir your/build/directory
-      cd your/build/directory
-      cmake -G Ninja -DCMAKE_EXPORT_COMPILE_COMMANDS=ON path/to/llvm/sources
+  $ mkdir your/build/directory
+  $ cd your/build/directory
+  $ cmake -G Ninja -DCMAKE_EXPORT_COMPILE_COMMANDS=ON path/to/llvm/sources
