This repo contains tutorial to Git and particularly GitHub

Several important topics include:

create a new repository on the command line

echo "# testing" >> README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin https://github.com/jsrpy/testing.git
git push -u origin master

push an existing repository from the command line

git remote add origin https://github.com/jsrpy/testing.git
git push -u origin master

Problems when creating new repo from command line

You could possible run into error when trying to push your local files to your github repo, because there exists LICENCE.txt and some other stuff comes along with it. In such case run the following two lines to fast-forward the latest history to your local:

git fetch
git rebase origin/master

You should now able to git push -u origin master

The Correct Way

Install Git & Create Github Account

If your machine is not pre-installed with, follow instructions here.
Register an account og Github.

Create Repository & Upload Files

Create a repo on github webpage (with or without Licence & Readme files)
At your local drive, create a directory called 'repo' which shall be used to sync all works with github.
In command line, git clone url the SSH of your newly created repo.
You should see your new repo folder (~/repo/repo_name) downloaded and sync on your local drive.
Drop codes and files you wish to publish in that folder.
git add * > git commit -m 'some message' > git push
Refresh your github repo page and you should see your codes and files uploaded!

To Sync Updates from Github

When your collaborators or others make new changes to a repo, your local is no longer synced or updated.

So whenever before doing anything, you should:

git fetch to check if there are any new changes.
git pull to pull all new changes to your loca.
Viola, you are now up-to-dated and you can add changes on your machine and push your works!

Deleting Files

If you manually delete some files in your local folder:

git add * will not stage the deleted files (check it with git status).
Use git add -u instead to stage the deleted files before committing.
