 ### Prerequisites
 
 #### PyTorch Nightlies
-Some features (especially fine-tuning with FSDP + PEFT) currently require PyTorch nightlies to be installed. Please make sure to install the nightlies if you're using these features following [this guide](https://pytorch.org/get-started/locally/).
+If you want to use PyTorch nightlies instead of the stable release, go to [this guide](https://pytorch.org/get-started/locally/) to retrieve the right `--extra-index-url URL` parameter for the `pip install` commands on your platform.
 
 ### Installing
 Llama-recipes provides a pip distribution for easy install and usage in other projects. Alternatively, it can be installed from source.
 
 #### Install with pip
 ```
-pip install --extra-index-url https://download.pytorch.org/whl/test/cu118 llama-recipes
+pip install llama-recipes
 ```
 
 #### Install with optional dependencies
 Llama-recipes offers the installation of optional packages. There are three optional dependency groups.
 To run the unit tests we can install the required dependencies with:
 ```
-pip install --extra-index-url https://download.pytorch.org/whl/test/cu118 llama-recipes[tests]
+pip install llama-recipes[tests]
 ```
 For the vLLM example we need additional requirements that can be installed with:
 ```
-pip install --extra-index-url https://download.pytorch.org/whl/test/cu118 llama-recipes[vllm]
+pip install llama-recipes[vllm]
 ```
 To use the sensitive topics safety checker install with:
 ```
-pip install --extra-index-url https://download.pytorch.org/whl/test/cu118 llama-recipes[auditnlg]
+pip install llama-recipes[auditnlg]
 ```
 Optional dependencies can also be combines with [option1,option2].
