+**Model Description** 
+
+OpenNMT model for English-Galician using a transformer architecture. 
+
+**How to translate**
+
++ Open bash terminal
++ Install [Python 3.9](https://www.python.org/downloads/release/python-390/)
++ Install [Open NMT toolkit v.2.2](https://github.com/OpenNMT/OpenNMT-py)
++ Translate an input_text using the NOS-MT-gl-en model with the following command:
+
+```bash 
+onmt_translate -src input_text -model NOS-MT-gl-en.pt -output ./output_file.txt -replace_unk -gpu 0
+```
++ The result of the translation will be in the PATH indicated by the -output flag.
+
+**Training**
+
+In the training we have used authentic and synthetic corpora from [ProxectoNós](https://github.com/proxectonos/corpora). The former are corpora of translations directly produced by human translators. The latter are corpora of English-Portuguese translations, which we have converted into English-Galician by means of Portuguese-Galician translation with Opentrad/Apertium and transliteration for out-of-vocabulary words. 
+
+**Training process**
+
++ Tokenization of the datasets made with linguakit tokeniser https://github.com/citiususc/Linguakit
++ The vocabulary for the models was generated through the script [learn_bpe.py](https://github.com/OpenNMT/OpenNMT-py/blob/master/tools/learn_bpe.py) of OpenNMT
++ Using .yaml in this repository you can replicate the training process as follows
+
+```bash 
+onmt_build_vocab -config  bpe-gl-en_emb.yaml -n_sample 100000
+onmt_train -config bpe-gl-en_emb.yaml
+```
+
+**Hyper-parameters** 
+
+The parameters used for the development of the model can be directly consulted in the same .yaml file bpe-en-gl_emb.yaml 
+
+**Evaluation** 
+
+The BLEU evaluation of the models is made with a mixture of internally developed tests (gold1, gold2, test-suite) and other datasets available in Galician (Flores).
