+### Dev Container Support
+
+If you prefer using a dev container for development, NetBird now includes support for dev containers. 
+Dev containers provide a consistent and isolated development environment, making it easier for contributors to get started quickly. Follow the steps below to set up NetBird in a dev container.
+
+#### 1. Prerequisites:
+
+* Install Docker on your machine: [Docker Installation Guide](https://docs.docker.com/get-docker/)
+* Install Visual Studio Code: [VS Code Installation Guide](https://code.visualstudio.com/download)
+* If you prefer JetBrains Goland please follow this [manual](https://www.jetbrains.com/help/go/connect-to-devcontainer.html)
+
+#### 2. Clone the Repository:
+
+Clone the repository following previous [Local NetBird setup](#local-netbird-setup).
+
+#### 3. Open in project in IDE of your choice:
+
+**VScode**:
+
+Open the project folder in Visual Studio Code:
+
+```bash
+code .
+```
+
+When you open the project in VS Code, it will detect the presence of a dev container configuration.
+Click on the green "Reopen in Container" button in the bottom-right corner of VS Code.
+
+**Goland**:
+
+Open GoLand and select `"File" > "Open"` to open the NetBird project folder.
+GoLand will detect the dev container configuration and prompt you to open the project in the container. Accept the prompt.
+
+#### 4. Wait for the Container to Build:
+
+VsCode or GoLand will use the specified Docker image to build the dev container. This might take some time, depending on your internet connection.
+
+#### 6. Development:
+
+Once the container is built, you can start developing within the dev container. All the necessary dependencies and configurations are set up within the container.
+
+
