 This is a quick guide to get **bitsery** up and running in a matter of minutes.
 The only prerequisite for running bitsery is a modern C++11 compliant compiler, such as GCC 4.9.4, clang 3.4, MSVC 2015, or newer.

+**bitsery** can be directly included in your project or installed anywhere you can access header files.
 Grab the latest version, and include directory `bitsery_base_dir/include/` to your project.
 There's nothing to build or make - **bitsery** is header only.

 **bitsery** is very lightweight, so we need to explicitly include what we need.
-* `<bitsery/bitsery.h>` is a core header, that includes our Serializer and Deserializer
-* `<bitsery/adapter/buffer.h>` in order to write/read data we need specific adapter, depending on what underlying buffer will be. In this example we'll be using std::vector as our buffer, so we include buffer adapter.
-* <bitsery/traits/...> traits tells library how efficiently serialize particular container.
