Adding info to website wiki re updating regular content

[LauraUSDS]

In an effort to make the usds.gov website more sustainable (and get institutional knowledge out of people's heads)....it would be helpful to have some documentation in the wiki around how to edit the regular text/content. I see there's instructions for updating the people and product features, but not how to, say, fix a typo on the homepage or switch out a blurb on the mission page, and so on.

Consider me your test case for any non-technical people who would like to keep the website content updated but don't know how ;)
