+    .venv\scripts\activate
+    ```
+

+
+    ```shell
+    python3 -m venv .venv
+    source .venv/bin/activate
+    ```
+
+2. Navigate to the `src` directory:
+
+    ```shell
+    cd src
+    ```
+
+3. Install required Python packages:
+
+    ```shell
+    python -m pip install -r requirements.txt
+    ```
+
+4. Run the local server:
+
+    ```shell
+    python -m uvicorn "api.main:create_app" --factory --reload
+    ```
