First, backup your current ~/.config/:

cp -r ~/.config ~/.config.bak

Then, navigate to ~/.config and initialize a git repository with default branch name main:

git init --initial-branch=main

Add remote repository:

git remote add origin https://github.com/Orion-zhen/dot-config.git

Fetch content and reset current commit to main:

git fetch && git reset --hard origin/main

Associate local branch with remote branch:

git branch --set-upstream-to origin/main

Finally, copy the backup files:

cp -rn ~/.config.bak/* ~/.config/

Parameter -n will not overwrite existing config files.
