Ensure the working file is from the latest version of the source file 8. Only Check-out the file being worked upon 9. Review every change before committing; utilize the diff function! 10. Use the ignore button for files that should not be committed, consider adding pre-commit filters to prevent the wrong kinds of files (such as accidental check-in of personal user settings docs) from entering the source control ย่อ
