Using Themes Results in Failure to Serve

[joesan]

Bug Report

I created a new Zola project and in the themes folder, I downloaded a Github repo of a theme that I'm interested in, but upon doing zola serve, I run into errors.

Environment

Ubuntu 20.04
rustc 1.50.0 (cb75ad5db 2021-02-10)

Zola version:
zola 0.14.1

Expected Behavior

I would have expected that the blog uses the theme and renders

Current Behavior

joesan@joesan-InfinityBook-S-14-v5:~/Projects/Private/github-docs/my-blog$ zola serve
Building site...
Checking all internal links with anchors.

Successfully checked 0 internal link(s) with anchors.
-> Creating 0 pages (0 orphan), 0 sections, and processing 0 images
Error: Failed to render section '/home/joesan/Projects/Private/github-docs/my-blog/content/_index.md'
Reason: Failed to render 'index.html' (error happened in a parent template)
Reason: Variable config.extra.navbar_items not found in context while rendering 'index.html'

Step to reproduce

$ zola init myblog
$ cd themes
$ git clone https://github.com/RatanShreshtha/DeepThought.git
$ cd ..
$ zola serve

You need to have a look at the theme README: https://github.com/RatanShreshtha/DeepThought#how-to-serve
Every theme can have some require config

I did follow the documentation and the associated README, but something is wrong. I have also given the steps to reproduce and I have also added the theme to config.toml, but still it results in this failure.

[Keats]

You need to put navbar_items in the [extra] section like so:

[extra]
navbar_items = [
 { code = "en", nav_items = [
  { url = "$BASE_URL/", name = "Home" },
  { url = "$BASE_URL/posts", name = "Posts" },
  { url = "$BASE_URL/docs", name = "Docs" },
  { url = "$BASE_URL/tags", name = "Tags" },
  { url = "$BASE_URL/categories", name = "Categories" },
 ]},
]

Ok now the confusion is where this extra should be placed. I have it in the config.toml which is located inside the themes&DeepThought folder, but I need to bring it out in the config.toml of the top level folder.

There is some fundamental documentation missing. Could this be because of the fact that I have git cloned the DeepThought theme inside the themes folder. My understanding was this is how I should do.
