Answer 1

--> Move to your project folder

cd /location

First Check Your Status

git status

Add files

git add

Commit Now

git commit -m “Commit Now”

Use your Remote location / Address

git remote add origin https://github.com/user/projname.git

To see Remotes

git remote -v

Push now

git push <remote> <branch>

Force Push

git push -f <remote> <branch>

Answer 2

Update :

Gemfile :

group :development, :test do
 # Call 'byebug' anywhere in the code to stop execution and get a  debugger console
 gem 'byebug'
 # Use sqlite3 as the database for Active Record
gem 'sqlite3'
end
group :development do
 # Access an IRB console on exception pages or by using <%= console  %> in views
gem 'web-console', '~> 2.0'

  # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
 gem 'spring'

end

group :production do
gem 'pg', '~> 0.11'
gem 'rails_12factor'
end

except those gems all the other have to be on the top and we should use 'pg' gem for production and 'sqlite3' for development
