+# Self-hosting with AWS
+
+This guide provides instructions for self-hosting the Mollie commercetools connector on AWS.
+
+To get started, you need to have a Docker image for the connector.
+
+## Docker Image
+
+This Dockerfile is designed to create a Docker image for a Node.js application using a multi-stage build process. It separates the build environment from the runtime environment to optimize the final image size.
+
+**File path:** [Dockerfile](https://github.com/mollie/commercetools-connector/blob/main/processor/Dockerfile)
+
+### Prerequisites
+
+- Docker installed on your machine.
+- Basic knowledge of Docker commands.
+
+### Building the Docker Image
+
+To build the Docker image, navigate to the directory containing the Dockerfile and run the following command:
+
+```bash
+docker build -t your-image-name .
+```
+
+Replace `your-image-name` with a name of your choice for the Docker image.
+
+### Running the Docker Container
+
+After building the image, you can run the container using the following command:
+
+```bash
+docker run -p 8080:8080 your-image-name
+```
+
+This command maps port 8080 of the container to port 8080 on your host machine.
+
+### Accessing the Application
+
+Once the container is running, you can access the application by navigating to `http://localhost:8080` in your web browser.
+
+### Stopping the Container
+
+To stop the running container, you can use the following commands:
+
+```bash
+docker ps # Find the container ID
+docker stop <container_id>
+```
+
+Replace `<container_id>` with the actual ID of the running container.
+
+### Notes
+
+- Ensure that your application is configured to listen on the correct port (8080).
+- The image is built with production dependencies only, ensuring a smaller footprint.
+
+## Setup Scripts
+
+By using the API setup endpoint below, the connector URL will be the original URL of Express to install necessary configurations and extensions on commercetools.
+
+### Install Connector Configurations
+
+**Endpoint:** `POST {connectorUrl}/processor/install`  
+**Response:**
+
+- On success: Returns a success message with a status code of 200.
+- On failure: Returns an error message with a status code of 400 or other relevant error codes.
+
+### Uninstall Connector Configurations
+
+**Endpoint:** `POST {connectorUrl}/processor/uninstall`  
+**Response:**
+
+- On success: Returns a success message with a status code of 200.
+- On failure: Returns an error message with relevant error codes.
