 ### Building
 
-To initialize the repository don't forget to execute `git submodule update --init` to pull the submodules.
-* __Windows__:
-1) Open the *.SLN* file.
-2) Build the projects in *__BUILD_BEFORE* folder: right-click on every project > *Build*.
-3) Press *BUILD* > *Build Solution* or *Rebuild Solution*.
-* __Linux & Mac OSX__:
-If you want to build with LLVM, then LLVM 3.8 is required.
-`cd rpcs3 && cmake CMakeLists.txt && make && cd ../` then run with `cd bin && ./rpcs3`.
