 This command will start the SITMUN Administration Application and map port 80 in the container to port 80 on the host machine. 
 The application should now be accessible at http://localhost on your machine.

+## Development Container support
+
+A development container (or dev container for short) allows you to use a container as a full-featured development environment. 
+The provided devcontainer file uses `mcr.microsoft.com/devcontainers/universal:2` and installs **node 12.1.1**.
+
+```json
+{
+  "image": "mcr.microsoft.com/devcontainers/universal:2",
+  "features": {
+  },
+  "postCreateCommand": "bash -i -c 'nvm install 12.11.1'"
+}
+```
+
+### Development Build Arguments
+
+The development for the SITMUN Administration Application takes three arguments during the build stage:
+
+- `GITHUB_TOKEN`: A personal access token from GitHub used to authenticate with GitHub’s package registry when downloading dependencies.
+- `BASE_HREF`: Specifies the base URL for the application, used by Angular for routing.
+- `CONFIGURATION`: Specifies the build configuration for the Angular application (i.e. `testdeployment` and `prod`).
+
+### Building the application
+
+To build the application, run the following command in the terminal:
+
+```bash
+npm set //npm.pkg.github.com/:_authToken $our_github_token
+npm ci
+npm run build -- --configuration=testdeployment --baseHref=/
+```
+
+Replace `your_github_token` with your actual GitHub token. Adjust the `BASE_HREF` and `CONFIGURATION` as needed.
+
+These commands will build the application. The output will be available in `dist/admin-app`.
