Workflow for new projects

Scheme Image for Example

FIRST GIT WORKLOW

On your local machine

• cd <foldername> : navigate to where you want to make a new folder

REMEMBER: It is really important to already be in the project folder

• take <foldername> : create a new folder and navigate in it (take is a combi of mkdir and cd)
• mkdir <foldername>: create new folders you need
• touch <filename> : create new files you need
• touch README.md: create a README.md to describe your project
• git init : initiate git in your first created folder, when all files and folders are created
• touch .gitignore : create a .gitignore - file
• ls -la : look for hidden files, you dont want to uplaod to Git / Github
• echo '.DS_Store' >> .gitignore: write filenames and folders in .gitignore
• git add -A : add everything to the Stage (Stage is a pool for commits)
• git commit -m "Initial commit" : Initial commit (Commit messages should start with a capital letter)

FIRST GITHUB-WORKFLOW

On your web browser

• Create a new Repository on GITHUB (https://github.com/)
  • repository-name = local-folder-name
  • choose public or private (public is recommended)
  • don't initialize this repository with a readme or gitignore
• next Page: Quicksetup
  • choose SSH
  • copy and paste first link in Terminal (to connect your local repository with your remote repository): git remote add origin git@github.com:USERNAME/REPOSITORY.git
    • press Enter

SECOND GIT WORKLOW

On your local machine

• git push -u origin main OR

  • git push: push the local repository to remote
    • you will get a message like this: git push --set-upstream origin main
    • copy, paste, enter

• now check if the repository is on Github, by refreshing the page of the repository

• git branch readme : edit README.md and create a new branch

• git branch : check branch

• git switch readme : switch to readme-branch

• ls -la : check if your README.md is here

• code README.md : open and edit your README.md in VS Code (remember this language is Markdown)

  • save your README.md

• git status: check changes

• git add README.md: add README.md to Stage

• git commit -m "Edit README.md" : commit README.md

• git push : push to Github

SECOND GITHUB-WORKFLOW

On your web browser

• go in to the repository
  • compare & pull request
  • leave a comment and create pull request
• IF your Code is reviewed and okay, than merge the pull request
  • confirm merge
  • delete branch

THIRD GIT WORKLOW

On your local machine

• git switch main : switch to main-branch
• git pull : pull your Github-Repository with your local
• git branch : check your branches
• git branch -d readme : delete feature branch
• git branch : Check branch again
