To bring a new feature from any branch to the main branch, you can use the command "git merge" or "git pull command" to get new features from the same branch.
Conflicts come into picture when a user has some changes in local and he tries to pull the latest code from remote, if the remote varies in content of the same file then conflict arises, and other thing when user has some changes in local branch and he tries to merge another branch which has different content in it.
To resolve the conflicts in git, edit the conflicting files, discuss with your team and keep whatever required and remove what is not needed. Then git add, git commit and push. Git knows that you are in the middle of a merger, so it sets the parents of the commit correctly.
Once you merge your development branch into the main branch, you don’t need a development branch. To delete a branch use the command to delete local branch "git branch -d < localBranchName >" to delete remote branch "git push origin --delete < remoteBranchName >".
"Rebasing" is an alternative to merging in git.
Syntax used to rebase the branch is 'git rebase
‘git remote add origin URL’ just adds remote repository's origin to your git config that specifies a name for a particular URL. While, ‘git clone URL’ copies the entire git repository located at the URL to the local.
