Hi Rakesh
you will have to download this file from this link Download openemr-7.0.2.tar.gz (OpenEMR) on your pc.
upload it via ftp software like filezilla which is free again.
next unzip the files from via ssh window of ur server.
run it eg. your website name xyz.com/openemr
the installation process will start.
let it create the database, but u will have to enter root user name and password etc.
regards 
github is for developers who plan to make changes to open source software files and send back to the original owner for incorporating the changes into the master copy.
@Robert_James I have already done the setup. I want to edit some code and add some features so that I can deploy through git and make all the changes that I made.
then better to install visual studio code on your computer and you will be able to edit any file and run the code too in visual studio.
I’m not sure if this helps, you may know all of this already, but this is what i’m doing:
i have installed git locally - my set up is a test environment - i use docker to run both server and client on my ubunt desktop.
so i have git installed, i then use local branches to try out different things, make changes etc. I also have my own account on github, so i can upload my branches to that, and from there i can do PRs to contribute code to the project. but also github then servers as a backup for my work and a repo (which i think you are doing already)
i have found the wiki document ‘Git for dummies’ really useful - Git for dummies - OpenEMR Project Wiki, Using Git with OpenEMR - OpenEMR Project Wiki also looks interesting.
