 `ko version` prints version of ko. For not released binaries it will print hash
 of latest commit in current git tree.
 
-### Strict Mode
-
-It can be difficult for `ko` to determine whether a string in a YAML file is
-intended to be an import path, due to typos, non-`package main` packages, and
-conflicts between import paths and common strings (e.g., a package whose import
-path is `busybox`). To solve this, `ko` supports "Strict Mode".
-
-When referencing an import path in the YAML file, prefix the string with the
-string `ko://` (e.g., `ko://github.com/my/repo/cmd/foo`). Then, when calling
-`ko apply` or `ko resolve`, pass `--strict`. If a string with the `ko://` prefix
-is not determined to be a valid import path, the command will fail, rather than
-passing it through to the resolved YAML.
