 ## Model description
 
-More information needed
+This is a model for Sinhala language text generation which is fine-tuned from the base llama-2-7b-chat-hf model.
+
+Currently the capabilities of themodel are extremely limited, and requires further data and fine-tuning to be useful. Feel free to experiment with the model and provide feedback.
+
+### Usage example
+
+```python
+from transformers import AutoTokenizer, AutoModelForCausalLM, pipeline
+
+tokenizer = AutoTokenizer.from_pretrained("Thimira/sinhala-llama-2-7b-chat-hf")
+model = AutoModelForCausalLM.from_pretrained("Thimira/sinhala-llama-2-7b-chat-hf")
+
+pipe = pipeline(task="text-generation", model=model, tokenizer=tokenizer, max_length=200)
+
+prompt = "ඔබට සිංහල භාෂාව තේරුම් ගත හැකිද?"
+result = pipe(f"<s>[INST] {prompt} [/INST]")
+print(result[0]['generated_text'])
+```
 
 ## Intended uses & limitations
 
-More information needed
+The Sinhala-LLaMA models are intended for assistant-like chat in the Sinhala language.
+
+To get the expected features and performance from these models the LLaMA 2 prompt format needs to be followed, including the INST and <<SYS>> tags, BOS and EOS tokens, and the whitespaces and breaklines in between.
