# Version Control ## Version Control & Git * **Version Control**: is a way to keep track of your files at different points in time. Using it is like having a giant UNDO button for your project. It solves a problem that might look familiar if you’ve ever seen documents with names like Report\_2014\_1.doc, Report\_2014\_2.doc, Report\_2014\_3.doc, or budget-v7.xls to keep track of your different versions. * Fluency in at least one version control system is an essential skill for a developer, designer, and manager alike. * There are many systems out there like RCS, CVS, and Subversion, Perforce, Bazaar, and Mercurial. Here we use the most popular open source one: Git! * **Git**: was developed by Linux creator Linus Torvalds to host the Linux kernel. It is a command-line program that is designed in the Unix tradition. That is why you need to have knowledge of how to use the Unix-style commmand line. ## Git Basics 01 & 02 Git basics 01 & 02 are introduction to local and online git system. We will also teach you how to submit your completed exercises through Github & CodiTech. Then we will test you with a simple git exercise [git basics trial](/docs/general/02_setup/03_git/git-basics-trial.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
