Let's solve this issue in a simple way.
First, you need to install the git tool with dnf tool:
[root@desk mythcat]# dnf -y install git
Let's see the version of this tool with a regular user:[mythcat@desk ~]$ git --version
git version 2.21.0
Let's set up the user for my GitHub account:[mythcat@desk ~]$ git config --global user.name "catafest"
[mythcat@desk ~]$ git config --global user.email "catafest@yahoo.com"
You can see it later with this command:[mythcat@desk ~]$ git config --list
[mythcat@desk ~]$ git config --global --list
I used this commands to create a folder for my git projects:[mythcat@desk ~]$ mkdir project_github
[mythcat@desk ~]$ cd project_github/
Now I can download my GitHub project named flask_yt from here:[mythcat@desk project_github]$ git clone https://github.com/catafest/flask_yt.git
Cloning into 'flask_yt'...

If you don't have one then you can create your new project on your GitHub account. Let's make some changes into README.md file:[mythcat@desk project_github]$ cd flask_yt/
[mythcat@desk flask_yt]$ vim README.md
...
Now I can use git tool:[mythcat@desk flask_yt]$ git status
On branch master
Your branch is up to date with 'origin/master'.
Changes not staged for commit:
(use "git add ..." to update what will be committed)
(use "git checkout -- ..." to discard changes in working directory)
modified: README.md
no changes added to commit (use "git add" and/or "git commit -a")
[mythcat@desk flask_yt]$ git add *
[mythcat@desk flask_yt]$ git commit -m "first commit"
[master 56f1e53] first commit
1 file changed, 1 insertion(+)
Now I can use my username and password from GitHub when I run this command:[mythcat@desk flask_yt]$ git push origin master
