+# OpenWebText & Llama-3-8B Example
 
+This repository contains scripts for computing influence scores on the subset of OpenWebText dataset. 
+The pipeline is inspired by [the LoggIX](https://github.com/logix-project/logix/tree/main/examples/language_modeling).
+Install the necessary packages:
 
 ```bash
-torchrun --standalone --nnodes=1 --nproc-per-node=2 analyze.py --factor_batch_size 8 \
-    --factor_strategy ekfac
+pip install -r requirements.txt
 ```
 
+## Training
+
+We will use the pre-trained model [from HuggingFace](https://huggingface.co/meta-llama/Meta-Llama-3-8B).
+
+## Computing EKFAC Factors
 
 ```bash
 torchrun --standalone --nnodes=1 --nproc-per-node=4 fit_factors.py --factor_batch_size 4
-```

+
+
+The `generate.py` folder contains a code to generate response of the Llama-3-8B model given certain prompt.
+I saved some prompt and completition pair to the directory `data/data.json`.
