 ### Overview
 
 Pixi is built using several game development libraries by others in the Zig community, as well as a C library for handling zipped files. The dependencies are as follows: 
-  - **mach-core**: Handles windowing and input, and uses the new zig package manager. This library and dependencies will be downloaded to the cache on build.
-  - **nfd_zig**: Native file dialogs wrapper, copied into the src/deps folder.
-  - **zgui**: Wrapper for Dear Imgui, which is copied into the src/deps/zig-gamedev folder.
-  - **zmath**: Math library, primarily using this for vector math and matrices. As above, this is copied into the src/deps/zig-gamedev folder.
-  - **zstbi**: Wrapper for stbi provided by zig-gamedev. This handles loading and resizing images. As above, this is copied into the src/deps/zig-gamedev folder.
-  - **zip**: Wrapper for the zip library, copied into the src/deps folder.

 Outside of the `src` folder, we have `assets` which contain all assets that we would like to be copied over next to the executable and used by Pixi at runtime.
