Git-Cheat-Sheet

Git phases:

1. Working Tree: Area where you perform all the modifications (contains Track and untrack files)
2. Staging area : Contains all of the information about what files and changes are goingt to be commited next
3. Git directory: History of all track files and changes

• Tracked files are files from are working tree that were passed to the Staging areas
• Untracked files are files that remain at our working tree

ADVANCE GIT

FORKING

A way of creating a copy of the given repository so that it belongs to our user. To do a pull request (correct master code) you need to fork the repo and create a new branch. You can only create 1 pull request per branch, though 1 pull request may have multiple commits

CONTINUOUS INTEGRATION (CI/CD)

Continuos integration enables us to check our code is up and running everytime we create a commit In ordet to apply CI with github you can use many 3rd parties solutions such as:

1. Travis
2. Jankins
