 The `EdgeML/c_reference/` directory is broadly structured into the following sub-directories:
 
 - **include/**: Contains the header files for various lower level operators and layers.
-- **models/**: Contains the optimized source code and header files for various models built by stiching together different layers and operators. Also contains the layer weights and hyper-parameters for the corresponding models as well (stored using `Git LFS`).
