How to download Jenkins

Jenkins is a tool used for CI / CD. Are you wondering what is CI and CD? Ok let me explain that first.

Continuous Integration (CI) is a process of integrating code changes from multiple developers in a single project .The code is tested immediately after the changes or commit, Whenever the code is committed , the code is built and tested.

Continuous Deployment / Delivery (CD) , when the test is passed , the build is tested in deployment. If the deployment is successful, the code is pushed to production and delivered.

So continuous integration / deployment is continuous process of commit, build , test , and deploy.
