+# Documentation for "build-winccoa-docker-image" Repository
+
+This repository hosts a GitHub Action workflow for
+- downloading the current WinCC OA version from winccoa.com and
+- generating and uploading Docker images of WinCC OA.
+
+The workflow is defined in `.github\workflows\generate-winccoa-image.yml`.
+
+## Setting Up
+
+### Create environment
+By default, for all workflow runs, an environment with the name `staging` is used.
+
+Create all required environments and adapt the logic in the workflow (`get_environment -> env_check`) if you want to use multiple environments.
+
+### Required Secrets
+- `ETM_USERNAME`: Username for winccoa.com
+- `ETM_PASSWORD`: Password for winccoa.com
+- `DOCKER_USER`: DockerHub username
+- `DOCKER_PASSWORD`: DockerHub password
+
+### Required environment variables
+- `DOCKER_IMAGE`: Name of the Docker image, e.g. `mydockerhubuser/winccoa`
+
+### Triggering the Workflow
+The workflow is triggered on:
+- Push to `main`, `release/*`, `develop`, and `develop/*` branches.
+- Published releases.
+
+## Workflow Overview
+
+### Get Environment
+- **Environment Setup**: Gets the desired environment
+
+### Preparation
+- **Download Current WinCC OA Version**: Requires ETM_USERNAME and ETM_PASSWORD secrets for authentication​​
+- **Extract Version Information**: Processes a ZIP filename to determine the WinCC OA version​​
+- **Prepare Data for Docker Image Build**: Involves unzipping data and preparing it for Docker build​​.
+
+### Docker Image Generation
+- **Docker Setup**: Sets up Docker and builds a temporary image
+- **Docker Build and Push Images**: Builds and pushes Docker images for different targets
+- **Docker Build Teardown**: Tears down the Docker setup post-build​​
+
+## Dockerfile Targets and Tags
+The `build-docker/Dockerfile_install` includes targets like `api`, `server`, and `uiserver` with the prefix `winccoa`. Each target corresponds to a possible tag of the resulting Docker image.
+
+The really built targets are defined in the step `Docker build and push images`.
+
+### Modify or Add New Targets
+
+1. **Adapt Dockerfile**: Define a new target in `build-docker/Dockerfile_install` in the form of `FROM <base> as winccoa<targetname>` or modify an existing one
+2. **Edit Workflow File**: In the `.github/workflows` directory, open the workflow file `generate-winccoa-image.yml`
+3. **Add/Modify Steps**:
+   - Under the `Docker build and push images` step, modify the list of targets in the for loop include your new target or modify the existing one.
+   - The default list defines the targets: `api server uiserver`
+
+### Testing Your Changes
+- It is highly recommended testing changes locally if possible, all docker commands can be run locally as well
+- Once changes are verified locally, test the changes by triggering the workflow
+- Monitor the build process to ensure your changes are correctly built and pushed
+
+## Example
+Given:
+- Docker image base name: `mydockerhubuser/winccoa`
+- Downloaded WinCC OA filename `WinCC_OA_3.19_linux_debian_x86_64_P007.zip`
+- Extracted version: `3.19.7`
+- List of targets: `api server uiserver`
+
+Resulting Docker image names:
+- `mydockerhubuser/winccoa:v3.19.7-api` from target `winccoaapi`
+- `mydockerhubuser/winccoa:v3.19.7-server` from target `winccoaserver`
+- `mydockerhubuser/winccoa:v3.19.7-uiserver` from target `winccoauiserver`
+
+These images are built and pushed to DockerHub using the provided credentials.
