 ## How to Install
 
-* Install [Docker](https://docs.docker.com/engine/install/) and [Docker Compose](https://docs.docker.com/compose/install/)
-* Install [Python 3.10.14](https://www.python.org/downloads/)
-* In `./tests-functional`, run `pip install -r requirements.txt`
-* **Optional (for test development)**: Use Python virtual environment for better dependency management. You can follow the guide [here](https://akrabat.com/creating-virtual-environments-with-pyenv/):
+1. Install [Docker](https://docs.docker.com/engine/install/) and [Docker Compose](https://docs.docker.com/compose/install/)
+2. Install [Python 3.10.14](https://www.python.org/downloads/)
