This document provides an overview of pipelines and continuous integration/deployment tools. It discusses who needs pipelines, what pipelines are and their main features, when to use pipelines, where pipelines can be found (GitLab, Bitbucket, GitHub, CircleCI, TravisCI), and why pipelines are important. The key benefits outlined are that pipelines integrate with repositories, are simple to use, don't require extra servers, replace tools like Jenkins, and enable isolated testing. The document also compares GitLab and Bitbucket pipelines, noting differences in where they run, task configuration, stages, and SSH key handling. Finally, it introduces Deployer PHP as a deployment tool that executes tasks remotely based on a release/folder structure configured via PHP files
