+# SITMUN Administration Application
 ![Build Status](https://github.com/sitmun/sitmun-admin-app/workflows/CI/badge.svg)
 [![Quality Gate](https://sonarcloud.io/api/project_badges/measure?project=org.sitmun%3Asitmun-admin-app&metric=alert_status)](https://sonarcloud.io/dashboard?id=org.sitmun%3Asitmun-admin-app)
 
+The SITMUN Administration Application is a web-based application built using TypeScript, JavaScript, npm, and Angular.
 
-# sitmun-admin-app
-Administration application for the SITMUN system.
+## Docker Support
+
+The application is containerized using Docker, as defined in the Dockerfile. The Dockerfile is divided into two stages:
+
+1. **Build Stage**: Based on Node.js, this stage is responsible for building and compiling the frontend of the application. 
+   It uses npm to manage dependencies and Angular for building the application.
+2. **Production Stage**: Based on Nginx, this stage serves the compiled application. 
+   The compiled application from the build stage is copied into the Nginx container and served from the `/usr/share/nginx/html/` directory.
+
+### Dockerfile Build Arguments
+
+The Dockerfile 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 Docker Image
+
+To build the Docker image for the SITMUN Administration Application, use the `docker build` command. 
+This command includes the image name and any necessary build arguments.
+
+Example command to build the Docker image:
+
+```bash
+docker build -t sitmun-admin-app --build-arg GITHUB_TOKEN=your_github_token --build-arg BASE_HREF=/ --build-arg CONFIGURATION=testdeployment .
+```
+Replace `your_github_token` with your actual GitHub token. Adjust the `BASE_HREF` and `CONFIGURATION` as needed.
+
+## Docker Compose Support
+
+To deploy the SITMUN Administration Application using Docker Compose, create a `docker-compose.yml file that defines the services for your application.
+
+### Steps to Create a docker-compose.yml File
+
+1. Create a `docker-compose.yml` file in the root directory of your project. 
+2. Define a service for the SITMUN Administration Application in the `docker-compose.yml` file. 
+   This service should use the Docker image built from the `Dockerfile`, specify the ports to expose, and include any necessary environment variables or build arguments.
+3. Start your application by running the `docker-compose up command in the terminal.
+
+### Example docker-compose.yml File
+
+```yaml
+version: '3.8'
+services:
+  sitmun-admin-app:
+    build:
+      context: .
+      dockerfile: Dockerfile
+      args:
+        GITHUB_TOKEN: your_github_token
+        BASE_HREF: /
+        CONFIGURATION: testdeployment
+    ports:
+      - "80:80"
+ ```
+
+Replace `your_github_token` with your actual GitHub token. Adjust the `BASE_HREF` and `CONFIGURATION` as needed.
+
+### Starting the Application with Docker Compose
+
+To start the application, run the following command in the terminal:
+
+```bash
+docker-compose up
+```
+
+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.
