+# Code - OSS Development Container
+
+This repository includes configuration for a development container for working with Code - OSS in an isolated local container or using [Visual Studio Codespaces](https://aka.ms/vso).
+
+> **Tip:** The default VNC password is `vscode`. The VNC server runs on port `5901` with a web client at `6080`. For better performance, we recommend using a [VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/). Applications like the macOS Screen Sharing app will not perform as well. [Chicken](https://sourceforge.net/projects/chicken/) is a good macOS alternative.
+
+## Quick start - local
+
+1. Install Docker Desktop or Docker for Linux on your local machine. (See [docs](https://aka.ms/vscode-remote/containers/getting-started) for additional details.)
+
+2. **Important**: Docker needs at least **4 Cores and 6 GB of RAM (8 GB recommended)** to run full build. If you on macOS, or using the old Hyper-V engine for Windows, update these values for Docker Desktop by right-clicking on the Docker status bar item, going to **Preferences/Settings > Resources > Advanced**.
+
+    > **Note:** The [Resource Monitor](https://marketplace.visualstudio.com/items?itemName=mutantdino.resourcemonitor) extension is included in the container so you can keep an eye on CPU/Memory in the status bar.
+
+3. Install [Visual Studio Code Stable](https://code.visualstudio.com/) or [Insiders](https://code.visualstudio.com/insiders/) and the [Remote - Containers](https://aka.ms/vscode-remote/download/containers) extension.
+
+    ![Image of Remote - Containers extension](https://microsoft.github.io/vscode-remote-release/images/remote-containers-extn.png)
+
+    > Note that the Remote - Containers extension requires the Visual Studio Code distribution of Code - OSS. See the [FAQ](https://aka.ms/vscode-remote/faq/license) for details.
+
+4. Press <kbd>Ctrl/Cmd</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd> and select **Remote - Containers: Open Repository in Container...**.
+
+    > **Tip:** While you can use your local source tree instead, operations like `yarn install` can be slow on macOS or using the Hyper-V engine on Windows. We recommend the "open repository" approach instead since it uses "named volume" rather than the local filesystem.
+
+5. Type `https://github.com/microsoft/vscode` (or a branch or PR URL) in the input box and press <kbd>Enter</kbd>.
+
+6. After the container is running, open a web browser and go to [http://localhost:6080](http://localhost:6080) or use a [VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/) to connect to `localhost:5901` and enter `vscode` as the password.
+
+Anything you start in VS Code or the integrated terminal will appear here.
+
+Next: **[Try it out!](#try-it)**
+
+## Quick start - Codespaces
+
+>Note that the Codespaces browser-based editor cannot currently access the desktop environment in this container (due to a [missing feature](https://github.com/MicrosoftDocs/vsonline/issues/117)). We recommend using Visual Studio Code from the desktop to connect instead in the near term.
+
+1. Install [Visual Studio Code Stable](https://code.visualstudio.com/) or [Insiders](https://code.visualstudio.com/insiders/) and the [Visual Studio Codespaces](https://aka.ms/vscs-ext-vscode) extension.
+
+    ![Image of VS Codespaces extension](https://microsoft.github.io/vscode-remote-release/images/codespaces-extn.png)
+
+    > Note that the Visual Studio Codespaces extension requires the Visual Studio Code distribution of Code - OSS.
+
+2. Sign in by pressing <kbd>Ctrl/Cmd</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd> and selecting **Codespaces: Sign In**. You may also need to use the **Codespaces: Create Plan** if you do not have a plan. See the [Codespaces docs](https://aka.ms/vso-docs/vscode) for details.
+
+3. Press <kbd>Ctrl/Cmd</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd> and select **Codespaces: Create New Codespace**.
+
+4. Use default settings (which should include **Standard** 4 core, 8 GB RAM Codespace), select a plan, and then enter the repository URL `https://github.com/microsoft/vscode` (or a branch or PR URL) in the input box when prompted.
+
+5. After the container is running, open a web browser and go to [http://localhost:6080](http://localhost:6080) or use a [VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/) to connect to `localhost:5901` and enter `vscode` as the password.
+
+6. Anything you start in VS Code or the integrated terminal will appear here.
+
+## Try it!
+
+This container uses the [Fluxbox](http://fluxbox.org/) window manager to keep things lean. **Right-click on the desktop** to see menu options. It works with GNOME and GTK applications, so other tools can be installed if needed.
+
+Note you can also set the resolution from the command line by typing `set-resolution`.
+
+To start working with Code - OSS, follow these steps:
+
+1. In your local VS Code, open a terminal (<kbd>Ctrl/Cmd</kbd> + <kbd>Shift</kbd> + <kbd>\`</kbd>) and type the following commands:
+
+    ```bash
+    yarn install
+    bash scripts/code.sh
+    ```
+
+2. After the build is complete, open a web browser and go to [http://localhost:6080](http://localhost:6080) or use a [VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/) to connect to `localhost:5901` and enter `vscode` as the password.
+
+3. You should now see Code - OSS!
+
+Next, let's try debugging.
+
+1. Shut down Code - OSS by clicking the box in the upper right corner of the Code - OSS window through your browser or VNC viewer.
+
+2. Go to your local VS Code client, and use Run / Debug view to launch the **VS Code** configuration. (Typically the default, so you can likely just press <kbd>F5</kbd>).
+
+    > **Note:** If launching times out, you can increase the value of `timeout` in the "VS Code", "Attach Main Process", "Attach Extension Host", and "Attach to Shared Process" configurations in [launch.json](../.vscode/launch.json). However, running `scripts/code.sh` first will set up Electron which will usually solve timeout issues.
+
+3. After a bit, Code - OSS will appear with the debugger attached!
+
+Enjoy!
