+## Development with Dev Container and GitHub Codespaces
+
+This repository provides a Dev Container to easily set up a development environment. Using Dev Container allows you to work in a consistent development environment with pre-configured dependencies and tools, whether locally or in the cloud with GitHub Codespaces.
+
+### Prerequisites
+
+**For Local Development:**
+
+* [Docker Desktop](https://www.docker.com/products/docker-desktop/) or any other compatible container runtime (e.g., Podman, OrbStack) installed.
+* [Visual Studio Code](https://code.visualstudio.com/) with the [Remote - Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) installed.
+
+**For GitHub Codespaces:**
+
+* A GitHub account.
+
+### Starting Dev Container
+
+**Using Visual Studio Code (Local):**
+
+1.  Clone the repository.
+2.  Open the repository in Visual Studio Code.
+3.  Open the command palette in Visual Studio Code (`Ctrl + Shift + P` or `Cmd + Shift + P`) and execute `Dev Containers: Reopen in Container`.
+
+**Using GitHub Codespaces (Cloud):**
+
+1.  Navigate to the repository on GitHub.
+2.  Click the "<> Code" button.
+3.  Select the "Codespaces" tab.
+4.  Click "Create codespace on main" (or your desired branch).
+
+### Dev Container Configuration
+
+Dev Container settings are configured in `.devcontainer/devcontainer.json`. In this file, you can set the Docker image to use, extensions to install, port forwarding, and more. This configuration is used both for local development and GitHub Codespaces.
+
+### Development
+
+Once the Dev Container is started, you can proceed with development as usual. The container already has the necessary tools and libraries installed. In GitHub Codespaces, you will have a fully configured VS Code in your browser or desktop application.
+
+### Stopping Dev Container
+
+**Using Visual Studio Code (Local):**
+
+To stop the Dev Container, open the command palette in Visual Studio Code and execute `Remote: Close Remote Connection`.
+
+**Using GitHub Codespaces (Cloud):**
+
+GitHub Codespaces will automatically stop after a period of inactivity. You can also manually stop the codespace from the Codespaces menu in GitHub.
