IntelliJ IDEA Version Control

Version Control is a system which records the every modification in a file or a set of files over time so that we can recall specific version later. It allows us to revert selected files back to a previous state, entire project back to a previous state, compare the changes over time and so on. It could also help us to easily recover our lost file.

IntelliJ IDEA IDE supports many version controls such as Git, CVS, TFS, GitHub, Subversion, Mercurial etc. In this section, we will discuss about the most important version controls i.e. Git.
