+# Adding a new microservice
+
+This document outlines the steps required to add a new microservice to the Online Boutique application.
+
+## 1. Create a new directory
+
+Create a new directory for your microservice within the `src/` directory. The directory name should be the name of your microservice.
+
+## 2. Add source code
+
+Place your microservice's source code inside the newly created directory. The structure of this directory should follow the conventions of the existing microservices. For example, a Python-based service would include at minimum the following files:
+
+- `README.md`: The service's description and documentation.
+- `main.py`: The application's entry point.
+- `requirements.in`: A list of Python dependencies.
+- `Dockerfile`: To containerize the application.
+
+Take a look at existing microservices for inspiration.
+
+## 3. Create a Dockerfile
+
+Create a `Dockerfile` in your microservice's directory. This file will define the steps to build a container image for your service.
+
+Refer to this example and tweak based on your new service's needs: https://github.com/GoogleCloudPlatform/microservices-demo/blob/main/src/frontend/Dockerfile
+
+## 4. Create Kubernetes manifests
+
+Create a new directory under `kustomize/components/` in the root of the repository for your microservice. Inside this directory, add the necessary Kubernetes YAML files for your new microservice. This typically includes:
+
+- A **Deployment** to manage your service's pods.
+- A **Service** to expose your microservice to other services within the cluster.
+
+Ensure you follow the existing naming conventions and that the container image specified in the Deployment matches the one built by your `cloudbuild.yaml` and `skaffold.yaml` files.
+
+Refer to this example and tweak based on your new service's needs: https://github.com/GoogleCloudPlatform/microservices-demo/tree/main/kustomize/components/shopping-assistant
+
+## 5. Update the root `kustomization.yaml` file
+
+Add your newly created component to the root kustomization file so it gets picked up by the deployment cycle.
+
+The file is available here: https://github.com/GoogleCloudPlatform/microservices-demo/blob/main/kustomize/kustomization.yaml
+
+## 6. Update the root `skaffold.yaml`
+
+Add your newly created service to the root skaffold file so the images build correctly.
+
+The file is available here: https://github.com/GoogleCloudPlatform/microservices-demo/blob/main/skaffold.yaml
+
+## 7. Update the Helm chart
+
+Add your newly created service to the Helm chart templates and default values.
+
+The chart is available here: https://github.com/GoogleCloudPlatform/microservices-demo/tree/main/helm-chart
+
+## 8. Update the documentation
+
+Finally, update the project's documentation to reflect the addition of your new microservice. This may include:
+
+- Adding a section to the main `README.md` if the service introduces significant new functionality.
+- Updating the architecture diagrams in the `docs/img` directory.
+- Adding a new document in the `docs` directory if the service requires detailed explanation.
