+## The patch names
+
+These patch files should be named <number>-<description>.patch.
+The patch files coming with Buildroot should not contain any package version reference in their filename.
+The field <number> in the patch file name refers to the apply order, and shall start at 1
+It is preferred to pad the number with zeros up to 4 digits, like git-format-patch does. E.g.: 0001-foobar-the-buz.patch
