+## How to use
+
+First please make sure to install `pip install transformers`. First download model: 
+
+```python
+from transformers import M2M100ForConditionalGeneration, M2M100Tokenizer
+import torch
+
+def translate(input_text, lang):
+    input_ids = tokenizer(input_text, return_tensors="pt")
+    generated_tokens = model.generate(**input_ids, forced_bos_token_id=tokenizer.get_lang_id(lang))
+    return tokenizer.batch_decode(generated_tokens, skip_special_tokens=True)
+
+model_name = "cartesinus/iva_mt_wslot-m2m100_418M-0.1.0-en-es"
+tokenizer = M2M100Tokenizer.from_pretrained(model_name, src_lang="en", tgt_lang="es")
+model = M2M100ForConditionalGeneration.from_pretrained(model_name)
+```
+
+Then you can translate either plain text like this:
+```python
+print(translate("set the temperature on my thermostat", "es"))
+```
+or you can translate with slot annotations that will be restored in tgt language:
+```python
+print(translate("wake me up at <a>nine am<a> on <b>friday<b>", "es"))
+```
+Limitations of translation with slot transfer:
+1) Annotated words must be placed between semi-xml tags like this "this is \<a\>example\<a\>"
+2) There is no closing tag for example "\<\a\>" in the above example - this is done on purpose to omit problems with backslash escape
+3) If the sentence consists of more than one slot then simply use the next alphabet letter. For example "this is \<a\>example\<a\> with more than \<b\>one\<b\> slot"
+4) Please do not add space before the first or last annotated word because this particular model was trained this way and it most probably will lower its results
