#### Jenkins Jenkins is an open-source automation server written in Java. It provides plugins for building, deploying, and automating any project. Jenkins facilitates continuous integration and continuous delivery in software projects by automating parts of the development process. Jenkins' core functionality is centered around pipelines that can be defined either through a text file named "Jenkinsfile" in the source code repository or through the graphical user interface. A pipeline contains a series of steps that allow for the modeling and automation of the software delivery process.
