What is Git after all?

Distributed Version Control System - All Repositories are equal even your local one!

From https://medium.com/@eduoshaun/difference-between-git-and-github-807f1a57d438

Install Git locally

https://git-scm.com/downloads

Start using the repo run in terminal:

git clone https://github.com/ValRCS/RCS_Data_Analysis_Python_09_2019.git

clones whole repo in the current working directory from which you run git clone
git log shows revision history with SHA1 hash value for each revision

Version

git --version shows current git version

Update automagically original repo: git pull from the same directory

git pull is like two commands into one
git fetch + git merge pulls changes from default origin(this repo) into your local repo and merges them

Edit/Move Files in local clone from command line terminal

git status show current status
git add . from project root to stage changes
git status to make sure
git commmit -m "My helpful commit message" to commmit locally
git push origin to push back to master repo (Github will ask to login and pw if no SSH set)

If you want to work on specific revision

git clone URL
cd to Projectdirectory
git reset --hard SHA1 where SHA1 is SHA1 of the revision you want
git pull to get back to HEAD revision

Reset to master branch

git fetch --all

git reset --hard origin/master

Note: this will overwrite any changes you might have made to the files locally
