Use git to save your changes

[bitfishxyz]

Asume there is a folder mygit and no files in it.

initialize reposity

git init

then git will create a folder named .git inside mygit.

Notice:If any folder or file 's name begin with ., it will be hidden. You can use ls -a to see any hidden files in a folder.

This folder will save changes but it will ignore itself's changes.

working directory -- stage -- timeline

there are three comcepts you must understand.

• working directory: the files inside mygit but outside .git.
• timeline: It save history of your changes, the information is saved in .git
• stage: a mid-situation from you working dir to timeline.

working directory saves you recent files, but stage and timeline save you changes!!!!
