 Installation
 ------------
 
-To use LLaMBDA, we recommend you first create an isolated environment with python 3.9 (or higher):
+We recommend creating a new virtual environment using venv before installing LLaMBDA. To do so, please follow instructions [here](https://docs.python.org/3/library/venv.html).
 
 .. code-block:: console
 
-    conda create python=3.9 --name llambda-env
-
-
-Activate the new environment before installing `llambda`.
-
-.. code-block:: console
-    
-    conda activate llambda-env
-
-The shell should now look like `(llambda-env) $`.
-
-Install LLaMBDA using pip directly from the GitHub repository.
-
-.. code-block:: console
-
-    (llambda-env) $ pip install --user git+https://github.com/cvs-health/llambda.git
-
-
-If you would like to access your virtual env from a notebook, install it as a Jupyter kernel:
-
-.. code-block:: console
-
-    python kernel install --name "llambda-env" --user
+    pip install git+https://github.com/cvs-health/llambda.git
