 A CRNN model for Persian OCR. This model is based on a simple CNN + LSTM architecture inspired by [this paper](https://arxiv.org/abs/1507.05717).
 More info about data and training will be provided soon.
 
+Note that this model is only optimized for scanned documents and supports input characters of up to 32 (For an end-to-end OCR pipeline, use a text detector 
+model first to extract text boxes preferrably in word-level and then use this model), but it can be used to be fine-tuned on other domains like license plate
+or handwritten texts.

 #### Usage
 ```
