fix building bug & add cd docs

[motahharm]

Hi there.

there was an bug when i run hugo server -D:

Error: add site dependencies: load resources: loading templates: "/mnt/d/MainProject/the-secret-bit/themes/cupper-hugo-theme/layouts/partials/head.html:14:1": parse failed: template: partials/head.html:14: unclosed action

I fix this

and I add cd command docs but it is draft

hi =)
im too happy that you helped us to improve the book.

this error is due to that you need the cupper theme in the theme directory
you have two choice for this:

1. download the theme into the directory manually
2. or you can clone the repo with --recurse-submodules

the problem with the draft is that you should mark draft as false in the cp.md file.
to do this edit line 4 of your file.
thanks you again. i will issue some problems then we will merge your commit.
