This document outlines the steps to initiate a Java web application project hosted on Google App Engine. It includes 5 milestones: 1) Create the project, 2) Install software, 3) Write the web service locally, 4) Deploy to the cloud, 5) Continue working in STS4. Key steps include generating a Spring Boot project, adding an API controller, and deploying using Maven and the gcloud CLI. The project can then be viewed running in the cloud and further developed in STS4 before redeploying changes.
