Project Description

The project aims to automate the building, testing, and deployment process of a web application using Jenkins and GitHub. The Jenkins pipeline will be triggered automatically by GitHub webhook integration when changes are made to the code repository. The pipeline will include stages such as building, testing, and deploying the application, with notifications and alerts for failed builds or deployments.
