-For the impatient, a quick guide for building on *nix systems:
+If you have a working C++ build environment, CMake, a current LLVM and
+libconfig++ (http://hyperrealm.com/libconfig/libconfig.html)
+available, there should be no big surprises, though.
 
- 1) Make sure your system has the necessary prerequisites:
-  - a working C++ build environment,
-  - CMake,
-  - LLVM 3.0+ (3.2 preferred),
-  - libconfig++ (http://hyperrealm.com/libconfig/libconfig.html).
-
- 2) Check out the library submodules, if you have not already:
+Do not forget to make sure all the submodules are up to date:
   $ cd ldc
   $ git submodule update --init
 
- 3) Build and install LDC:
-  $ mkdir build && cd build  # Out-of-source builds are recommended.
-  $ cmake ..
-  $ make
-  $ make install # Or run LDC directly from the bin/ directory.
-
-In case the above steps do not work, please first visit the extended
-documentation under the aforementioned URL.

 Some Linux distributions are also packaging a recent version of LDC,
 so building it manually might not be necessary.
