On your side navigation bar, go to Documents and then Governance Documents.
There are two ways to find a document in Governance Documents.
1. Search box
2. File Filters
Search Box
Type in the name or a "keyword" from the title. The search will reveal any document or folder that contains that keyword.
File Filters
Any "loose" documents not assigned to a folder will be found under the list of Folders.
You can sort the list of files by clicking on the menu to sort by Date, Title or Person.
The down arrow shows documents in ascending or descending order from most recently uploaded to the earliest upload for Date and alphabetically for People and Title.
