+If you wish to affect only a single repository (i.e., to assign
+attributes to files that are particular to one user's workflow), then
+attributes should be placed in the `$GIT_DIR/info/attributes` file.

 Sometimes you would need to override an setting of an attribute
 for a path to `unspecified` state.  This can be done by listing
 the name of the attribute prefixed with an exclamation point `!`.

  * Patterns read from the file specified by the configuration

+Which file to place a pattern in depends on how the pattern is meant to
+be used. Patterns which should be version-controlled and distributed to
+other repositories via clone (i.e., files that all developers will want
+to ignore) should go into a `.gitignore` file. Patterns which are
+specific to a particular repository but which do not need to be shared
+with other related repositories (e.g., auxiliary files that live inside
+the repository but are specific to one user's workflow) should go into
+the `$GIT_DIR/info/exclude` file.  Patterns which a user wants git to
+ignore in all situations (e.g., backup or temporary files generated by
+the user's editor of choice) generally go into a file specified by
+`core.excludesfile` in the user's `~/.gitconfig`.

 The underlying git plumbing tools, such as
