 It is strongly recommended that you leave `vendor/` unmodified, in whatever state dep puts it in. However, this isn't always feasible. If you have no choice but to modify `vendor/` for a particular project, then add the project root for that project to `noverify`. This will have the following effects:
 
 * `dep ensure` will ignore hash mismatches for the project, and only regenerate it in `vendor/` if absolutely necessary (prune options change, package list changes, version changes)
-* `dep check` will continue to report hash mismatches (albeit with an annotation about `noverify`) for the project, but will no longer exit 1. 
+* `dep check` will continue to report hash mismatches (albeit with an annotation about `noverify`) for the project, but will no longer exit 1.
 
 `noverify` can also be used to preserve certain excess paths that would otherwise be removed; for example, adding `WORKSPACE` to the `noverify` list would allow you to preserve `vendor/WORKSPACE`, which can help with some Bazel-based workflows.
