Purpose: Execute commands locally and have the server automatically pull your code from Git to the server. Automatic every time, no need to manually log into the server to download the code, or copy it.

Premise: Push your own project to git repository. Of course, if it is your own company project, you do not want to make the project public. Private repositories can be used, and then private repositories on Github are very expensive at $20 per month
