+---
+
+# Packaging Theia as a Docker Image
+
+Eclipse Theia Blueprint is an example product used as a reference on how to build IDE-like products based on the Eclipse Theia framework.
+Theia Blueprint assembles a selected subset of existing Theia features and extensions.
+We provide a Docker image for Theia Blueprint.
+In the respective git repository you can also find the source code for Theia Blueprint and the Dockerfile.
+This documentation will use these sources as a template. We will explain
+how to customize this template so you can build your own custom Theia-based product for the cloud.
+
+## Building a Docker Image
+
+The Docker build uses the `browser.Dockerfile` Dockerfile checked in at the root of the repository.
+
+The build itself consists of two stages.\
+In the `build-stage` we are building the workspace using `yarn` and perform some cleanup tasks to make the build results smaller.\
+The `production-stage` is based on a slim node base-image. Here we create a dedicated user, which will run the application, and the user's home directory.
+Additional tools required for the desired use of the application (like Git, a JDK for Java development, Maven, ...) are installed.
+The build results are copied from the `build-stage` and environment variables used by Theia are set.\
+Please check the comments in `browser.Dockerfile` for more detailed information about every step.
+
+You can build the docker image running `docker build -t theia-blueprint -f browser.Dockerfile .` at the root of the repository.
+
+You can run your image using `docker run -p=3000:3000 --rm theia-blueprint` and pointing your browser to http://localhost:3000.
+
+## Updating Bundled VS Code Extensions
+
+All VS Code extensions that are already included in the product at start-up, are defined in `applications/browser/package.json`.
+They are listed under the `theiaPlugins` property as key-value pairs.
+The keys can be freely chosen as long as they represent a valid folder name and are unique within the `theiaPlugins` property.
+We suggest using the extension’s unique identifier.
+The value is the download URL of the extensions.
+They will be downloaded automatically during the `docker build`.
+
+To remove an extension from the product, simply delete its entry.
+
+### Extension sources
+
+We use the [Open VSX Registry](https://open-vsx.org/) of the Eclipse Foundation to install extensions.
+It is an open and community-driven VS Code extension marketplace.
+More information can be found at [eclipse.org](https://www.eclipse.org/legal/open-vsx-registry-faq/).
+
+## Customizing Theia Extensions
+
+Eclipse Theia extensions can be added through `dependencies` in `applications/browser/package.json`.
+Like any other dependency, it will be installed via yarn.
+Similarly, removing an extension works by removing it from `dependencies`.
+For extensions already published on npm (or your private npm registry) this is all you need to do.
+
+An alternative approach is developing your extension inside Theia Blueprint’s mono repo.
+The advantage of doing this is that you don’t need to publish the extension and can build the product with the local version of the extension.
+This is facilitated by the lerna build already configured in the Theia Blueprint’s repository.
+It links the product and all extensions in the repository together during the build.
+
+The easiest way to create a new extension is to use the [official yeoman generator](https://www.npmjs.com/package/generator-theia-extension) for Theia extensions.
+Assuming you have [yeoman](https://yeoman.io/) globally installed on your system, simply create a new extension in the repository root with `yo theia-extension --standalone`.
+The `--standalone` flag is used to only create an extension but not a whole Theia application frame because it is already provided by the Theia Blueprint.
+After successfully generating the extension, add its folder name to the Theia Blueprint’s root `package.json` in the workspaces property.
+After adding the extension to the dependencies in `applications/browser/package.json` as described above, the new extension will be part of the built product.
+
+## Branding
+
+You can also add your own branding to the product by customizing the application icons and title, the welcome page and the About dialog.
+In addition, some parts of the installer can be customized.
+
+### Customizing the App
+
+#### Application Window Title
+
+The window title is the application’s name if no workspace is opened and `<workspace name> — <application name>` if a workspace is opened.
+The application name can be adapted in `applications/browser/package.json`:
+Open the file and adapt the value of property `theia.frontend.config.applicationName` to the desired name.
+
+### Customizing the Welcome Page
+
+The Eclipse Theia welcome page can be customized by binding a custom `WidgetFactory` for Theia’s `GettingStartedWidget`.
+This is done with Theia Blueprint in the theia-blueprint-product extension.
+The easiest way to customize the welcome page is to adapt the class `TheiaBlueprintGettingStartedWidget` in `theia-extensions/theia-blueprint-product/src/browser/theia-blueprint-getting-started-widget.tsx`.
+
+The widget is bound in `theia-extensions/theia-blueprint-product/src/browser/theia-blueprint-frontend-module.ts` like this:
+
+```typescript
+    bind(TheiaBlueprintGettingStartedWidget).toSelf();
+    bind(WidgetFactory).toDynamicValue(context => ({
+        id: GettingStartedWidget.ID,
+        createWidget: () => context.container.get<TheiaBlueprintGettingStartedWidget>(TheiaBlueprintGettingStartedWidget),
+    })).inSingletonScope();
+```
+
+To use another custom widget, remove this code and bind your widget correspondingly.
+
+### Customizing the About Dialog
+
+The Eclipse Theia about dialog can be customized by binding a custom subclass of Theia’s `AboutDialog` class to `AboutDialog`.
+This is done with Theia Blueprint in the theia-blueprint-product extension.
+The easiest way to customize the about dialog is to adapt the class `TheiaBlueprintAboutDialog` in `theia-extensions/theia-blueprint-product/src/browser/theia-blueprint-about-dialog.tsx`.
+
+The widget is bound in `theia-extensions/theia-blueprint-product/src/browser/theia-blueprint-frontend-module.ts` like this:
+
+```typescript
+isBound(AboutDialog) ? rebind(AboutDialog).to(TheiaBlueprintAboutDialog).inSingletonScope() : bind(AboutDialog).to(TheiaBlueprintAboutDialog).inSingletonScope();
+```
+
+To use another custom dialog widget, remove this code, extend Theia’s AboutDialog class, and (re)bind it as above.
