This document provides an overview of using Bitbucket Pipelines to build, test, and deploy projects from Bitbucket repositories. It discusses how Bitbucket Pipelines uses Docker containers to run build plans, benefits like faster feedback and reusable containers. It also covers enabling Pipelines for a repository, configuring the bitbucket-pipelines.yml file, and adding tests to a sample build plan by exporting Postman tests and adding a package.json file to run the tests during the build.
