Lockheed Martin uses mkdocs to document Harbor user procedures. The documentation is provided via a container in the Harbor k8s cluster. The downside is that users must manually open a separate web link to enter queries such as:
"how to request a new project"
"how to rotate a robot password"
We've tested a chatbot as a sidebar extension of chrome/edge but prefer the capability be embedded in Harbor web pages. The documentation files (.md) are stored in a llama vector.

We would like:

1. an ICON or 'left-side' Tab on each web page to access our company Harbor documentation
2. a chatbot icon or 'left-side' Tab allowing messaging on each web page to:
   2.1 Optionally integrate company MkDocs document files with Harbor Docs or completely replace Harbor Docs
   2.2 Execute Harbor functions if asked.
   2.3 Make chatbot Harbor UI page aware in order to prompt relevant user options and address/correct user errors.

Perhaps these functions can be added in incremental releases.
