+2. Since the project is developed using Python and Pytorch some necessary packages need to be installed. Install the necessary libraries and packages mentioned in **requirements.txt**. To install the necessary packages either use pip or create a new conda environment and install the minimum required packages as mentioned in the requirements file. To set up a python environment to run code using conda, you may follow the instructions below:
 
-3. Run the cells in Jupyter notebook to train a new agent on this environment. Pretrained agent's weights are also present in weights folder.
+    Create and activate a new environment with Python 3.6 and install dependencies
+
+    - Linux or Mac:
+      ```
+      conda create --name env-name python=3.6
+      source activate env-name
+      ```
