     | `all`  |  It's common for a big package to have a lot of interfaces, so mockery provides `all`. This option will tell mockery to scan all files under the directory named by `--dir` ("." by default) and generates mocks for any interfaces it finds. This option implies `recursive: True`. |
+    | `boilerplate-file` | Specify a path to a file that contains comments you want displayed at the top of all generated mock files. This is commonly used to display license headers at the top of your source code. |
     | `case` | mockery generates files using the casing of the original interface name.  This can be modified by specifying `case: underscore` to format the generated file name using underscore casing. |
     | `exclude` | This parameter is a list of strings representing path prefixes that should be excluded from mock generation. |
     | `exported` | Use `exported: True` to generate public mocks for private interfaces. |
