 ### Visual Studio (Windows)
-

 Going into `build` directory, you will find additional possibilities:
 - Projects for Visual Studio 2005, 2008 and 2010.
   + VS2010 project is compatible with VS2012, VS2013, VS2015 and VS2017.
 - Automated build scripts for Visual compiler by [@KrzysFR](https://github.com/KrzysFR), in `build/VS_scripts`,
   which will build `zstd` cli and `libzstd` library without any need to open Visual Studio solution.

 ### Buck
-

 You can build the zstd binary via buck by executing: `buck build programs:zstd` from the root of the repo.
 The output binary will be in `buck-out/gen/programs/`.

 ## Testing
 
 You can run quick local smoke tests by executing the `playTest.sh` script from the `src/tests` directory.
