+Before developing the course, you should set up the environment yourself:
+* For Windows:
+  ```shell
+  python3 -m venv .venv && .\.venv\Scripts\activate && pip install -r requirements.txt
+  ```
+
+* For Linux/MacOS:
+  ```bash
+  python3 -m venv .venv && source .venv/bin/activate && pip install -r requirements.txt
+  ```
