-
+This repository contains the backend code for the application. It utilizes **FastAPI** to quickly create a RESTful API that exposes the endpoints of the route optimizer.
 
 ## Getting Started
-- The code of the python application is located in the `src` directory.
-- Package management is handled with `pipenv` and the dependencies are listed in the `Pipfile`.
-- Since the application is aimed to be deployed in a container, the `Dockerfile` is provided to build the image.
+
+### Directory Structure
+- The code for the Python application is located in the `src` directory.
+- Package management is handled with **pipenv**, and the dependencies are listed in the `Pipfile`.
+- Since the application is designed to be deployed in a container, the `Dockerfile` is provided to build the image.
+
+### Setting Up the Development Environment
+
+To set up your development environment using **pipenv**, follow these steps:
+
+1. Install `pipenv` by running:
+    ```bash
+    sudo apt install pipenv
+    ```
+
+2. Create and activate a virtual environment:
+    ```bash
+    pipenv shell
+    ```
+
+3. Install the dependencies listed in the `Pipfile`:
+    ```bash
+    pipenv install
+    ```
+
+4. The virtual environment will be created under:
+    ```bash
+    ~/.local/share/virtualenvs/...
+    ```
 
 ### Deployment
 To deploy the backend docker container, we use kubernetes. Modifications to the backend are automatically pushed to a two-stage environment through the CI pipeline. See [deployment/README](deployment/README.md] for further information.
