can then be copied alongside and modified as appropriate. This second, modified
file is usually ignored to prevent accidentally committing it.
+[[files-in-gitignore-are-tracked]]
+I asked Git to ignore various files, yet they are still tracked::
+ A `gitignore` file ensures that certain file(s) which are not
+ tracked by Git remain untracked. However, sometimes particular
+ file(s) may have been tracked before adding them into the
+ `.gitignore`, hence they still remain tracked. To untrack and
+ ignore files/patterns, use `git rm --cached <file/pattern>`
+ and add a pattern to `.gitignore` that matches the <file>.
+ See linkgit:gitignore[5] for details.
