+- the "page last modified" data will only display if a page has a key called `last_modified_date`, formatted in some readable date format
+- `last_edit_time_format` uses Ruby's DateTime formatter; see examples and more information [at this link.](https://apidock.com/ruby/DateTime/strftime)
+- `gh_edit_repository` is the URL of the project's GitHub repository
+- `gh_edit_branch` is the branch that the docs site is served from; defaults to `master`
+- `gh_edit_view_mode` is `"tree"` by default, which brings the user to the github page; switch to `"edit"` to bring the user directly into editing mode
