To creat a repository of an exsisting project in github from your local server:

1. Create a new repository in Github website. To avoid errors, do not initialize the new repository with README, license, or gitignore files. (This is important as I did mistakes at the beginning after clicking add README)

2. Use the init command to initialize the local directory as a Git repository. For Git 2.27.1 or an earlier version, set the name of the default branch using && git symbolic-ref HEAD refs/heads/main:

   $ git init && git symbolic-ref HEAD refs/heads/main

3. Add the files in your new local repository. This stages them for the first commit.

   $ git add .

4. Commit the files that you’ve staged in your local repository.

   $ git commit -m “First commit”

5. At the top of your repository on GitHub.com’s Quick Setup page, click to copy the remote repository URL.

6. In the Command prompt, add the URL for the remote repository where your local repository will be pushed.

   $ git remote add origin REMOTEURL
   $ git remote -v
   #Verifies the new remote URL

7. Push the changes in your local repository to GitHub.com.

   $ git push origin main

To merge changes from the remote repo to local, such as after readme file was added in the remote repo:

1. Pulling changes from a remote repository

   $ git pull origin main

To add the README file locally:

1. First creat the README.md:

   $ touch README.md

2. Then add, commit and push the changes:

   $ git add .
   $ git commit -m “added readme”
   $ git push origin main

To merge changes from remote to local but the local files was also changed:

1. If you want remove all local changes - including files that are untracked by git - from your working copy, simply stash them:

   $ git stash push –include-untracked

2. If you don’t need them anymore, you now can drop that stash:

   $ git stash drop

3. Then you can pull from remote without errors:

   $ git pull origin main

Or

$ git fetch
$ git reset –hard HEAD
$ git merge ‘@{u}’

To sync with the local, push changes from the local to remote:

1. Add the updated files in your local repository, which tells Git that you want to include all of your changes in the next commit.

   $ git add .

2. Git commit takes a snapshot of those changes.

   $ git commit -m “description of changes”

3. To push the current branch and set the remote as upstream.

   $ git push –set-upstream origin main

Clone from a remote repository:

1. Using git clone cmd

   $ git clone REMOTEURL

Push git cloned repository to your own on GitHub:

After you have cloned a remote repository to your own repository, and then push to your own remote server, you will find a white arrow in the github repository and you cannot open it and see the contents inside. This white arrow means it is a nested folder. To remove it and show the contents, do:

1. If you don’t care about the history of that folder, delete locally its .git subfolder inside that folder using

   $ rm -rf .git

2. Then you would need to delete the gitlink entry:

   $ git rm –cache sub_folder_name

3. Finally, you can add, commit and push that folder content.
