+
+Implementation and source code of algorithms from paper: ***"Stealth edits for provably fixing or attacking large language models"***. 
+
+
+### Getting Started
+
+1. Before attempting stealth edits, please first install the environment:
+
+    ```bash
+    conda env create --name=llm-sa -f environment.yml
+    conda activate llm-sa
+    ```
+
+2. The model `llama-3-8b` requires you to apply for access. Please follow the instructions [here](https://huggingface.co/meta-llama/Meta-Llama-3-8B). You will also need to install `huggingface-cli` and input an [user access token](https://huggingface.co/docs/huggingface_hub/en/guides/cli).
+
+
+3. To start playing with stealth edit and attacks, please refer to the [Colab Demo](https://colab.research.google.com/github/qinghua-zhou/stealth-edits/blob/main/demos/colab_demo.ipynb) and the [Huggingface Demo](https://huggingface.co/spaces/qinghua-zhou/stealth-edits).
+
+### Experiments
+
+To reproduce experiments in the paper, please first run the extraction script:
+
+  ```bash
+  bash scripts/extract.sh
+  ```
+
+and then run edits and/or attacks and evaluation with the following scripts:
+
+  ```bash
+  bash scripts/edit.sh
+  bash scripts/eval.sh
+  ```
+
+It is recommended to distribute the experiments on multiple nodes.
