Approach to keep a feature_branch up to date with the development branch
Where more than one developer could be working in the feature_branch, creating branch using as base feature_branch
git checkout feature_branch
git pull origin feature_branch
git checkout development
git pull origin development
git checkout feature_branch
git merge development
git push origin feature_branch
In the same way, If you are working in a PR with base: feature_branch and you have conflict, then you can try
git checkout feature_branch
git pull origin feature_branch
git checkout branch_name
git merge feature_branch
git push origin branch_name
