I think we're still on the hook for this internally, but just flagging that I'm seeing the two links for Google Adwords (http://segment-docs-stage.s3-website-us-west-2.amazonaws.com/docsv2/connections/destinations/catalog/google-ads-classic/ and http://segment-docs-stage.s3-website-us-west-2.amazonaws.com/docsv2/connections/destinations/catalog/google-ads-gtag/ ) come up as 404s.

How are these paths being generated currently? Where is the left-nav built?

The files are at /destinations/catalog/adwords/index.md and destinations/catalog/google-adwords-new/index.md
