+You have access to the `*cobra.Command` pointer so there's not much you cannot do with this project compared to the more low-level Cobra, but there's one small, but important difference:
 
-Cobra only treats the first level of misspelled commands as an `unknown command` with "Did you mean this?" suggestions, see [see this issue](https://github.com/spf13/cobra/pull/1500) for more context. The reason this is, is because of the ambiguity between sub command names and command arguments, but that is throwing away a very useful feature for a not very good reason. We recently rewrote [Hugo's CLI](https://github.com/gohugoio/hugo) using this poackage, and found only one sub command that needed to be adjusted to avoid this ambiguity.
