+# Llama-2 Tokenizer (Mirror for KnowRL Project)
+
+This is a mirror of the tokenizer files from `meta-llama/Llama-2-7b-hf`, provided as a **public, gated-free** alternative for users who cannot access the original gated repo.
+
+## Why this mirror exists
+
+The KnowRL project's QuCo reward function uses an Infini-gram index built with the Llama-2 tokenizer. To query the index, the exact same tokenizer is required. Since `meta-llama/Llama-2-7b-hf` is gated, users without approved access cannot run QuCo.
+
+This repo contains **only the tokenizer files** (no model weights):
+- `tokenizer.json` — fast tokenizer
+- `tokenizer.model` — SentencePiece model
+- `tokenizer_config.json` — tokenizer configuration
+- `special_tokens_map.json` — special token mappings
+
+## Usage
+
+```python
+from transformers import AutoTokenizer
+tokenizer = AutoTokenizer.from_pretrained("UIC-R2-lab/llama2-tokenizer")
+```
+
+## License
+
+Follows the original [Llama 2 Community License Agreement](https://github.com/facebookresearch/llama/blob/main/LICENSE) from Meta.
