Find place to link the new "About data" pages

[dorothyyeager]

Summary

What we are after:
We made some "about data" pages. Right now you cannot access them unless you have the URL (https://www.fec.gov/campaign-finance-data/about-campaign-finance-data/). We need to find a spot to link them and add that link.

Related issues

• Publish "about this data" pages #3314

Action items

• Draft wording for the link
• Add a link in https://www.fec.gov/introduction-campaign-finance/how-to-research-public-records/ (touch base with Jason B before doing this)

Completion criteria

• You can get to https://www.fec.gov/campaign-finance-data/about-campaign-finance-data/ via a link from https://www.fec.gov/introduction-campaign-finance/how-to-research-public-records/

Future work

#3498 Expand About This Data and add a link in data section.

We've added an internal "learn more..." button to the data tutorials section of the "how to research public records" page: https://www.fec.gov/introduction-campaign-finance/how-to-research-public-records/#data-tutorials

Closing ticket.
