        ### Vendored Dependencies

       +Hugo uses [Go Dep](https://github.com/golang/dep) to vendor dependencies, but we don't commit the vendored packages themselves to the Hugo git repository.
        Therefore, a simple `go get` is not supported since `go get` is not vendor-aware.

        Due to the way Go handles package imports, the best approach for working on a
        Hugo fork is to use Git Remotes.  Here's a simple walk-through for getting
        started:
        
       -1. Fetch the Hugo sources as described above.
       +1. Install Go Dep and get the Hugo source:

       +    ```
       +        go get -u -v github.com/golang/dep/cmd/dep
       +        go get -u -v -d github.com/gohugoio/hugo
       +        ```

            ```
            cd $HOME/go/src/github.com/gohugoio/hugo
       +        dep ensure
