I'm a Drupal 8 newbie writing my first module. I have a functioning yet basic module to learn from. What I'm working on now is for it to get a value from a configuration page. If I go directly to the URL for the custom config page it works. What I'm having trouble with is getting a link to my custom config page to display on the main config page. I've been through every tutorial I can find on this topic and I just can't figure out why it's not working. I hope you all can help. Here's my yml files.
name: Item Request
description: Allow the public to request items for the District to purchase.
_title: 'Request an Item'
_permission: 'access content'
_title: 'Item Request'
_permission: 'access administration pages'
title: 'Item Request Form'
description: 'Settings for Item Request form"
Do see anything wrong in the .yml files? Is there anything I can do to troubleshoot this?
