On excluding *.DS_Store you might want to add to the instructions:

• untracked the file is you’ve already create a check-in in the phpbb directory

  git rm --cached *.DS_Store Then create a ignore file with touch .gitignore To edit it, on Mac you need to see hidden files os use (first finder is NOT capitalised): defaults write com.apple.finder AppleShowAllFiles -boolean true ; killall Finder add the line .DS_Store to the .gitignore file with a text editor save and revert hidden files to their normal state with defaults write com.apple.finder AppleShowAllFiles -boolean false ; killall Finder
