I read some articles and I tried to do through the command lines of GIT.
I installed git but I don't understand what are commands by which my code is available online.
D:\prjAutJava\ContentSpeedEdgeDriver\src\contentspeededgedriver>git push -u origin master
To https://github.com/Anda77/AutJava.git ! [rejected] master -> master (fetch first)
error: failed to push some refs to 'https://Anda77@github.com/Anda77/AutJava.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
