+### HPLT MT release v2.0
+
+This repository contains the English-Afrikaans (en->af) encoder-decoder translation model trained on HPLT v2.0 and OPUS parallel data. The model is currently available in Marian format and we are working on converting it to the Hugging Face format.
+
+### Model Info
+
+* Source language: English
+* Target language: Afrikaans
+* Data: HPLT v2.0 and OPUS parallel data
+* Model architecture: Transformer-base
+* Tokenizer: SentencePiece (Unigram)
+
+You can check out our [paper](https://arxiv.org/abs/2503.10267), [GitHub repository](https://github.com/hplt-project/HPLT-MT-Models/tree/main/v2.0), or [website](https://hplt-project.org) for more details.
+
+### Usage
+The model has been trained with [MarianNMT](https://github.com/marian-nmt/marian) and the weights are in the Marian format. 
+
+#### Using Marian
+To run inference with MarianNMT, refer to the [Inference/Decoding/Translation](https://github.com/hplt-project/HPLT-MT-Models/tree/main/v1.0#inferencedecodingtranslation) section of our GitHub repository. You will need the model file `model.npz.best-chrf.npz` and the vocabulary file `model.en-af.spm` from this repository.
+
+#### Using transformers
+We are working on this.
