Git
download here - https://git-scm.com/
When you make changes to your project, you will use Git for committing the changes. This is useful for:
- having a record of all stages of your code (which is good, for example, in case you make a mistake and need to roll back)
- sharing your code with others by using Git to push the code to the website Github
- moving your committed changes into a live website site automatically
Once you have installed Git, you will be able to write commands in ConEmu like:
- 'git init'
- 'git commit -m "updates all source files"'
- 'git push'
You can also install Sourcetree or another Graphical User Interface (GUI) for Git and Github, which will allow you to run these commands more easily, without the command line.
Even if you use a GUI for everything and never write "git..." in the command line, you still have to have the program Git installed for the GUI to work.
