hi! @abigaeljamie @kevinhatchoua @andrew-ronaldson I've got a draft up for adding initial AI guidelines to the site. I worked off of the doc that Abi and Kevin put together, but made some adjustments to cut down the length a little and group things around in different ways. Very open to any feedback/ideas to adjust based on what you all were envisioning!

@bekah-stephens has a design issue open to look at a layout for this content. patternfly/patternfly-design#1322

[bekah-stephens]

I shared a draft of the content layout with Erin yesterday and she referenced it to create this version. I think this is a good start to getting the AI content on the site!

[abigaeljamie]

These look great! I added a missing period, but otherwise no feedback :D

Wait to merge this until chatbot is ready

[andrew-ronaldson]

Content looks great. I was wondering for we should call the section PatternFly AI instead of just AI. That nav item can house chatbot extensions and all the other docs you've created

Nav name change
