+# Installation
+
+Since we are using PyTorch for hw2, we recommend using conda to manage the environment. Please refer to the [miniconda](https://docs.conda.io/en/latest/miniconda.html) homepage for a compact conda installation.
+
+You have two options for creating the environment of hw2
+
+* For mac users or a cpu-only installation, please remove the `pytorch-cuda` term in either ways.
+* To create a new conda environment, simply run `conda env create -f environment.yml`
+* If you want to install the package within the environment you created with hw1, please following the below steps:
+
+  ```bash
+  conda activate <hw1-env-name>
+  # we are using PyTorch 2.0!
+  # remove the pytorch-cuda=11.7 term if you are a mac user to want a cpu-only installation
+  conda install pytorch==2.0.0 pytorch-cuda=11.7 -c pytorch -c nvidia
+  pip install gymnasium[classic_control]==0.27.1
+  pip install matplotlib==3.7.1
+  # for hyperparameter management
+  pip install hydra-core==1.3.2
+  # for video recording
+  pip install moviepy==1.0.3
+  ```
+
+That's it! If you encounter any trouble creating the environment, please let us know :-)
