+Enter the directory and install dependencies:
+
+```
+yarn
+```
+
+### Start the Service
+
+> Remember to replace the MongoDB and Redis addresses in the config with your own
+
+Start in the test environment:
+
+```
+npm run start:dev
+```
+
+Start in the production environment:
+```
+npm run start
+```
+
+## Deployment and Release
+
+### Write Dockerfile
+
+```dockerfile
+# Use the official Node.js 12 lightweight image.
+# https://hub.docker.com/_/node
+FROM node:12-slim
+
+# Define the working directory
+WORKDIR /usr/src/app
+
+# Copy dependency definition files to the working directory
+COPY package*.json ./
+
+# Install dependencies in production mode
+RUN npm install --only=production
+
+# Copy local code to the working directory
+COPY ../function-to-run ./
+
+# Start the service
+CMD [ "node", "server.js" ]
+```
+
+### Upload the Code Package
+
+Compress all files in the directory into a zip:
