+## Developing with Visual Studio Code + devcontainer
+
+The easiest way to get started with custom integration development is to use Visual Studio Code with devcontainers. This approach will create a preconfigured development environment with all the tools you need.
+
+In the container you will have a dedicated Home Assistant core instance running with your custom component code. You can configure this instance by updating the `./devcontainer/configuration.yaml` file.
+
+**Prerequisites**
+
+- [git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
+- Docker
+  -  For Linux, macOS, or Windows 10 Pro/Enterprise/Education use the [current release version of Docker](https://docs.docker.com/install/)
+  -   Windows 10 Home requires [WSL 2](https://docs.microsoft.com/windows/wsl/wsl2-install) and the current Edge version of Docker Desktop (see instructions [here](https://docs.docker.com/docker-for-windows/wsl-tech-preview/)). This can also be used for Windows Pro/Enterprise/Education.
+- [Visual Studio code](https://code.visualstudio.com/)
+- [Remote - Containers (VSC Extension)][extension-link]
+
+[More info about requirements and devcontainer in general](https://code.visualstudio.com/docs/remote/containers#_getting-started)
+
+[extension-link]: https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers
+
+**Getting started:**
+
+1. Fork the repository.
+2. Clone the repository to your computer.
+3. Open the repository using Visual Studio code.
+
+When you open this repository with Visual Studio code you are asked to "Reopen in Container", this will start the build of the container.
+
+_If you don't see this notification, open the command palette and select `Remote-Containers: Reopen Folder in Container`._
+
+### Tasks
+
+The devcontainer comes with some useful tasks to help you with development, you can start these tasks by opening the command palette and select `Tasks: Run Task` then select the task you want to run.
+
+When a task is currently running (like `Run Home Assistant on port 9123` for the docs), it can be restarted by opening the command palette and selecting `Tasks: Restart Running Task`, then select the task you want to restart.
+
+The available tasks are:
+
+Task | Description
+-- | --
+Run Home Assistant on port 9123 | Launch Home Assistant with your custom component code and the configuration defined in `.devcontainer/configuration.yaml`.
+Run Home Assistant configuration against /config | Check the configuration.
+Upgrade Home Assistant to latest dev | Upgrade the Home Assistant core version in the container to the latest version of the `dev` branch.
+Install a specific version of Home Assistant | Install a specific version of Home Assistant core in the container.
+
+### Step by Step debugging
+
+With the development container,
+you can test your custom component in Home Assistant with step by step debugging.
+
+You need to modify the `configuration.yaml` file in `.devcontainer` folder
+by uncommenting the line:
+
+```yaml
+# debugpy:
+```
+
+Then launch the task `Run Home Assistant on port 9123`, and launch the debbuger
+with the existing debugging configuration `Python: Attach Local`.
+
+For more information, look at [the Remote Python Debugger integration documentation](https://www.home-assistant.io/integrations/debugpy/).
