## Building ## Using
Requires CMake and Vulkan installed on your system. Simply copy the `src/VkBootstrap.h` and `src/VkBootstrap.cpp` into your project
Alternatively, add this project as a git-submodule
```bash
git submodule add https://github.com/charles-lunarg/vk-bootstrap
```
Then add the project with cmake
```cmake
add_subdirectory(vk-bootstrap)
```
## Manually Building
Simple setup
```bash ```bash
git clone https://github.com/charles-lunarg/vk-bootstrap git clone https://github.com/charles-lunarg/vk-bootstrap
