 # MMLU Benchmark Example
 
-Evaluate language models on [MMLU (Massive Multitask Language Understanding)](https://arxiv.org/abs/2009.03300) with optional efficient evaluation via [DISCO](https://arxiv.org/abs/2510.07959).
+Evaluate language models on [MMLU (Massive Multitask Language Understanding)](https://arxiv.org/abs/2009.03300) with optional efficient evaluation via [DISCO (Diversifying Sample Condensation)](https://arxiv.org/abs/2510.07959).
 
 ## Installation
 
-For basic MMLU evaluation:
+Install [uv package manager](https://docs.astral.sh/uv/) as described [here](https://docs.astral.sh/uv/getting-started/installation/).
+
+Create Python environment:
+
+```bash
+uv venv --python 3.11
+```
+
+Install dependencies for basic MMLU evaluation:
 
 ```bash
-uv pip install .[mmlu]
+uv sync --extra mmlu
 ```
 
-For DISCO prediction (includes DISCO dependencies):
+Install dependencies for MMLU evaluation with DISCO:
 
 ```bash
-uv pip install .[disco]
+uv sync --extra disco
 ```
