+## Quickstart Guide
+> [!IMPORTANT]
+To build the frontend you need to download and install _Node.js_, and the _Node Package Manager_ (npm). You can
+download the latest release from their website: [NodeJS.org](https://nodejs.org/en/)
+
+First, clone this repository to your computer:
+```bash
+git clone [email protected]:DLR-SC/ESID.git
+cd ESID
+git checkout develop
+```
+> [!NOTE]  
+> The `develop` branch contains our latest developed features as outlined in our [Branching Strategy](/frontend/README.md#branching-strategy).
+
+Next, initialize the project by downloading and installing its dependencies:
+```bash
+cd frontend
+npm install
+```
+
+Once the dependencies are installed you can launch it locally with:
+```bash
+npm run start
+```
+This will host a server at [localhost:8080](http://localhost:8080/), where the website will be displayed.
