 ## Model description
 
-More information needed
+This DocVQA model, built on the Layout LM v2 framework, represents an initial step in a series of 
+experimental models aimed at document visual question answering. It's the "medium" version in a planned series, 
+trained on a mid-sized dataset of 5k samples (split between training and test) over 20 epochs. 
+The training setup was modest, employing mixed precision (fp16), with manageable batch sizes and a 
+focused approach to learning rate adjustment (warmup steps and weight decay). Notably, this model was 
+trained without external reporting tools, emphasizing internal evaluation. As the first iteration in a 
+progressive series that will later include medium (5k samples) and large (50k samples) models, this 
+version serves as a foundational experiment, setting the stage for more extensive and complex models in the 
+future.
