-### Known issue with `dep`
-
-There is a known problem with using Blackfriday v1 _transitively_ and `dep`.
-Currently `dep` prioritizes semver versions over anything else, and picks the
-latest one, plus it does not apply a `[[constraint]]` specifier to transitively
-pulled in packages. So if you're using something that uses Blackfriday v1, but
-that something does not use `dep` yet, you will get Blackfriday v2 pulled in and
-your first dependency will fail to build.
-
-There are couple of fixes for it, documented here:
-https://github.com/golang/dep/blob/master/docs/FAQ.md#how-do-i-constrain-a-transitive-dependencys-version

-Meanwhile, `dep` team is working on a more general solution to the constraints
