 Pattern matching works as follows:
 
-* To match all files with a `.txt` extension no matter what directory, use `**.txt`.
-* To match all files with a `.txt` extension _only at the root level of the repository_, use `*.txt`.
-* To match all files inside `resources/bin` and below, use `resources/bin/**`.
-* To match all files _immediately inside_ `resources/bin`, use `resources/bin/*`.
-* To match all files named `Makefile`, use `**Makefile`.
-* Matching a directory has no effect; the pattern `resources/bin` will not include/exclude files inside that directory; `resources/bin/**` will.
-* All files and patterns are normalized to lower case, so `**Makefile`, `**makefile` and `**MAKEFILE` are equivalent.
