Problem compiling from source (due to blackfriday versioning?)

[fe5hua]

Hi,
sorry if I did a stupid mistake compilling cook. I am quite new to go.
I am trying to compile cook from source, because I am on OpenBSD (amd64) and there are not precompiled binarys.
When following the instructions get an error compiling with the notice to go mod init. This results in a different error with notice go mod vendor. And finally I get an error undefined: blackfriday.Run which (after some digging) seems to be a result of using blackfriday v1.x with syntax from v2.

Here is my whole process:

user@hostname in ~/go/src
→ $ git clone https://github.com/ysim/cook.git

Yes, you're exactly right, I ran into this issue when I was making a release to migrate from dep to go modules.

The latest master should have the update with the fix in. Thank you for opening this issue!
