Add link to configure page

@dstol I think that you need to take a look inside the Complete example in Let Drupal 8 know about your module with an .info.yml file

And you will see this:

name: Hello World Module
description: Creates a page showing "Hello World".
package: Custom

type: module
core: 8.x

dependencies:
  - datetime:datetime
  - link:link
  - drupal:views

test_dependencies:
 - drupal:image

configure: hello_world.settings

php: 5.6

hidden: true

# Note: do not add the 'version'  property yourself!
# It will be added automatically by the packager on drupal.org.
version: 1.0

There are some spaces in the .info.yml file
