+## Requirements
+
+- [gcc](https://www.gnu.org/software/gcc/) **>= 7**

+## Installation
+
+[meta.hpp][meta] is a header-only library. All you need to do is copy the headers files from `headers` directory into your project and include them:
+
+```cpp
+#include "meta.hpp/meta.hpp"
+```
+
+Also, you can add the root repository directory to your [cmake](https://cmake.org) project:
+
+```cmake
+add_subdirectory(external/meta.hpp)
+target_link_libraries(your_project_target meta.hpp)
+```
+
+## Examples
+
+> coming soon
+
+## API
